Prologue — USD 84 Trillion Is Now Moving

In January 2025, Cerulli Associates published a report estimating that US baby boomers will transfer about USD 84 trillion in assets to children, grandchildren, and charities over the next 25 years. It is the largest wealth transfer in human history from a single generation to the next. Yet many will die without a will — Caring.com's 2024 survey found that only 32% of US adults have one.

That enormous gap created the will-SaaS boom of the mid-2020s. Trust & Will, FreeWill, LegalZoom Estate, and Rocket Lawyer captured the mass market, while Wealth.com and Vanilla seized the high-net-worth advisor market.

But it is not only assets that get transferred. When we die we leave behind:

  • Legal assets — real estate, deposits, equities, pensions, insurance proceeds
  • Digital assets — 100,000 photos on the iPhone, family videos on Google Drive, game inventory, Bitcoin in crypto wallets
  • Social graph — 1,500 Facebook friends, 5,000 Instagram followers, 200 KakaoTalk chat rooms
  • Trails of authentication — 200 accounts locked in a password manager, 2FA backup codes, an email inbox spanning a lifetime

Through the 2010s digital legacy was a fringe topic. By the mid-2020s it had become the centerpiece of every will SaaS. Apple Legacy Contact (iOS 15.2+), Google Inactive Account Manager, and Facebook Legacy Contact built OS- and platform-level answers, while 1Password, Bitwarden, and Dashlane built the password-manager-level answers.

This article walks straight through that landscape.

Chapter 1 · The 2026 Estate Planning Industry — By the Numbers

First, the market size. Estimates as of May 2026.

  • Global estate planning SaaS revenue — about USD 1.5 billion. Trust & Will's 2023 Series C (IVP-led, around USD 400 million valuation) and Wealth.com's 2024 Series B (about USD 97 million round) signal the trajectory.
  • US adult will ownership — about 32%. Caring.com 2024 survey. Down steadily from roughly 50% in the late 1990s.
  • Average will cost — USD 300-1,200 for a simple attorney-drafted will, USD 1,500-5,000 with trusts. DIY SaaS sits at USD 99-299.
  • USD 84 trillion wealth transfer — Cerulli Associates 2025 report, over the next 25 years (2024-2048).
  • Boomer share of US household wealth — about 50% (Fed SCF 2023).

Major player categories.

  • Password inheritance: 1Password Family Recovery, Bitwarden Emergency Access, LastPass Emergency Access, Dashlane Emergency
  • Crypto inheritance: Casa Inheritance, Unchained Capital
  • Korea: Samsung Life will trust, Mirae Asset Trust, KakaoTalk memorial account, NAVER memorial page
  • Japan: Mitsubishi UFJ Trust Bank, Mizuho Trust, family trust (kazoku-shintaku), Shukatsu Counselor Association, digital remains services

Chapter 2 · The 4-Layer Will Drafting Stack — 2026 Standard

Mass-market will SaaS has settled on a 4-layer stack.

[Will Drafting 4-Layer Stack — 2026]
  L1. Information gathering — family structure, asset list, digital asset inventory
  L2. Document generation   — Will, Trust, Power of Attorney, Healthcare Directive
  L3. Signing / notarization — self-signed + 2 witnesses, notary required in some states
  L4. Storage / access       — secure storage, trusted contact designation

Quickly through each layer.

  • L1 Information gathering — Trust & Will uses a roughly 20-minute form. Wealth.com involves the advisor working alongside the client.
  • L2 Document generation — AI-driven templates self-adjust to state law. California, New York, and Florida each have different trust and will requirements.
  • L3 Signing / notarization — about 40 of 50 states require self-signature plus two witnesses; the rest require a notary. Since COVID in 2020, Remote Online Notarization (RON) has been legalized in 33 states.
  • L4 Storage / access — Trust & Will recommends PDF download plus a safe deposit box. Wealth.com stores documents in a cloud vault.

Chapter 3 · Trust & Will — The DIY Trust Leader

Trust & Will (www.trustandwill.com) was founded in 2017 in San Diego by Cody Barbo. Its 2023 Series C, led by IVP, raised about USD 150 million at roughly a USD 400 million valuation. With partnerships including NerdWallet, Northwestern Mutual, and Notarize, it has anchored itself as the mass-market leader.

  • Pricing — Will plan about USD 199 (individual), Couple about USD 299. Trust plan about USD 599-799.
  • Coverage — all 50 states.
  • Included documents — Last Will and Testament, Revocable Living Trust (higher tiers), Power of Attorney, Healthcare Directive.
  • Differentiating features — Trusted Estate Plan (self-signed + notarization), Trust Funding (transferring assets into the trust).

Trust & Will's strength is user experience. About 20 minutes of form work generates both Will and Trust at once, and it works on mobile. The weak spot is that very complex cases (real estate in multiple states, private businesses, contested guardianship of minors) still need an attorney.

Since 2024 it has added an AI-powered Document Review feature: an AI reviews user-drafted documents and flags missing items. But the company repeatedly notes "this is not legal advice" — the standard line that any DIY legal SaaS uses to avoid Unauthorized Practice of Law (UPL) claims from state bar associations.

Chapter 4 · FreeWill — Evolution of the Nonprofit Model

FreeWill (www.freewill.com) was founded in 2017 in New York by Patrick Schmitt and Jenny Xia Spradling as a B Corp. It gives users free will creation while partnering with nonprofits (Red Cross, NPR, universities) to nudge users toward leaving part of their assets to charity — the so-called "Planned Giving" market.

  • Pricing — USD 0 to the user. Partner nonprofits pay license fees.
  • Cumulative wills drafted — about 1 million as of 2024. Total estate value pledged to nonprofits exceeds USD 11 billion.
  • Partner nonprofits — more than 1,500. Top US universities (Stanford, Harvard), environmental groups (Sierra Club, Nature Conservancy), religious organizations.
  • Included documents — Will, Living Trust, Power of Attorney, Healthcare Directive, Living Will.

FreeWill's business model is elegant. A free user creates a will in five minutes, with an option to leave part of their assets to a nonprofit baked in. Nonprofits pay license fees, but those costs are negligible relative to the average USD 78,000 of pledged estate value.

The catch is that it falls short on complex trusts and large estates. FreeWill explicitly markets itself for "simple wills" and recommends an attorney for assets above USD 5 million or complex family structures.

Chapter 5 · LegalZoom Estate — Mass-Market Giant

LegalZoom (www.legalzoom.com) was founded in 2001 in Los Angeles by Brian Liu, Brian Lee, Edward Hartman, and Robert Shapiro (famous as an O.J. Simpson attorney). It went public on Nasdaq in June 2021 at about a USD 7 billion market cap (since reduced). It is synonymous with the US DIY legal document market.

  • Pricing — Last Will about USD 89-179, Living Trust about USD 279-329, Estate Plan Bundle about USD 349.
  • Included documents — Will, Trust, Power of Attorney, Living Will, Pet Protection Plan.
  • Add-on services — attorney consultation (US LegalZoom Personal Legal Plan, about USD 39 per month).

LegalZoom is the symbol of the first-generation LegalTech wave. In the early 2010s state bar associations sued LegalZoom for UPL violations, with the 2012 North Carolina case the most famous — the court debated whether automated document generation by LegalZoom constituted unauthorized practice of law. It settled in 2015, and LegalZoom maintains that it is a "self-help tool, not legal advice."

In 2024 LegalZoom sunset Willing (the will-focused SaaS it had acquired in 2017). Willing users were migrated to the standard LegalZoom estate planning product. In 2025 LegalZoom shipped AI Assistant, which lets users ask natural-language questions like "Who gets my dog if I die?" and recommends appropriate clauses.

Chapter 6 · Rocket Lawyer Estate · Quicken WillMaker · Fabric

A quick sweep of LegalZoom's competitors.

Rocket Lawyer (www.rocketlawyer.com) — founded 2008 in San Francisco. Its differentiator is the subscription model (USD 39.99 per month). Includes Will, Trust, POA, and hundreds of other legal documents with unlimited drafting. Attorney consultation (On Call attorney) is also included.

Quicken WillMaker (www.willmaker.com / published by Nolo) — desktop software Nolo Press has published since 1985. Quicken Inc. acquired it in 2025. Priced at about USD 109 per year. The oldest DIY will tool, carrying forward the paper-book-plus-software era. Covers all 50 states except Louisiana, which has a civil-law tradition handled separately.

Fabric by Gerber Life (www.meetfabric.com) — founded 2017 in New York, acquired in 2022 by Western & Southern Financial Group (parent of Gerber Life). Bundles life insurance, a will, and a trust for children. The business model is a free will generator that funnels users toward life insurance enrollment.

Tomorrow Ideas (www.tomorrow.me) — founded 2017 in Seattle by Mike Heffring. A mobile-first free will app. Shut down in 2023 (no longer downloadable from app stores). A textbook case of being squeezed out by Trust & Will and FreeWill.

Chapter 7 · Wealth.com — AI Trust Tooling for Advisors

Wealth.com (www.wealth.com) was founded in 2022 in California by Tim White and Joe Cianciolo. Rather than the mass market, it serves RIAs (Registered Investment Advisors) and wealth managers as a B2B SaaS, helping advisors rapidly draft estate plans for high-net-worth clients (typically USD 5 million and up).

  • 2024 Series B — about USD 97 million, with GV (Google Ventures), Citi Ventures, and Brewer Lane Ventures participating.
  • Customers — about 700 RIAs covering approximately USD 1 trillion in assets under management.
  • Differentiating features — Ester (AI estate planning assistant), Family Office Suite, Estate Diagnostic.

Wealth.com's Ester, released in 2024, lets advisors upload a client's trust documents and have them automatically summarized, visualized, and gap-analyzed. For example, "Does this trust fully use the generation-skipping transfer tax (GSTT) exemption?" — the AI answers in a sentence.

The contrast with competitor Vanilla is that Wealth.com leans more on the advisor-and-client collaboration interface. Vanilla skews more toward advisor analytic tooling.

Chapter 8 · Vanilla — Estate Analytics for Advisors

Vanilla (www.justvanilla.com) was founded in 2019 in Seattle by Gene Farrell, Steve Lockshin, Adam Nash, and others. It raised about USD 11.5 million in Series A in 2022, with ICONIQ Capital leading a roughly USD 35 million Series B in 2024. Customers are mostly large RIAs and multi-family offices.

  • Customers — about 500 advisor firms covering more than 80,000 high-net-worth clients.
  • Differentiating features — Vanilla AI, Estate Plan Visualizer, Net Worth Tracker, Tax Modeling.

Vanilla's strength is visualization. Complex trust structures (GRATs, IDGTs, ILITs, CLATs, and so on) are rendered as diagrams. The grandparent-to-GST-trust-to-grandchild-to-baby-trust flow shows up on a single screen, letting an advisor walk a client through it in five minutes.

Vanilla AI launched in 2024. Upload a PDF of a trust document and the AI extracts key clauses (beneficiaries, trustees, distribution standards, termination triggers). A 50-page attorney-drafted trust document can be summarized in ten minutes.

Chapter 9 · EncoreEstate · WealthCounsel · Interactive Legal

Other players in the advisor market.

EncoreEstate Plans (www.encoreestate.com) — founded 2019 in Colorado. SaaS that lets attorneys deliver documents to clients. While Wealth.com and Vanilla are for advisors, EncoreEstate is for lawyers. Will and trust drafting, client portal, billing integration.

WealthCounsel (www.wealthcounsel.com) — founded 1997 in Utah. The oldest US estate-planning attorney network, with about 4,000 attorney members. WealthDocs (document generation SaaS), training programs, and an annual conference (the Symposium).

Interactive Legal (www.interactivelegal.com) — a document-generation system for lawyers operating since the 1980s. The "old but accurate" tool that veteran estate attorneys still rely on. Both cloud and desktop versions exist.

Chapter 10 · Snug Safety · Cake · Lantern · Empathy

The death-and-funeral-planning generation.

Snug Safety (www.getsnug.com) — founded 2020 in San Francisco. Brands itself as "modern death planning." It covers more than wills — family contacts, funeral preferences, digital asset inventory, pet care instructions, "letters to send after I'm gone." Free plus a premium tier at USD 16.66 per month.

Cake (www.joincake.com) — founded 2017 in Boston. End-of-life planning platform. Healthcare directives, funeral preferences, ethical wills (informal letters about values and legacy). Strong on healthcare partnerships.

Lantern (www.lantern.co) — founded 2018 in New York. Step-by-step guidance for "what does the family do after a death?" Death certification, social security notification, insurance claims, real estate disposition, grief care. No signup fee, premium USD 27 per year.

Empathy (www.empathy.com) — founded 2020 in Tel Aviv, focused on the US market. An app that combines bereavement care with administrative processing. When a family loses someone, an AI lays out step-by-step to-dos (death certification, bank cleanup, real estate appraisal). Raised USD 30 million in Series B in 2022.

Chapter 11 · Trustworthy — The Family Operating System

Trustworthy (www.trustworthy.com), founded in 2019 in California by Nathan Brunson and Lukasz Strzelec, is a "Family Operating System." It is not just for wills — every piece of important family information (insurance documents, real estate deeds, photos, kids' medical records, passwords) lives in a single vault.

  • Pricing — Free, Plus (USD 100 per year), Family (USD 200 per year).
  • What it holds — trust/will storage, insurance documents, real estate documents, child information, digital assets.
  • Differentiating features — AI Auto-categorize (automatically classifies uploaded PDFs), Trusted Advisor (share part of the vault with an attorney or CPA).

Think of Trustworthy as a "family vault" — what 1Password is to passwords. In 2024 it added AI-driven document analysis: upload an auto insurance card and the AI extracts "renewal date 2026-09-15, insurer GEICO, policy number XXX-XXX-XXX" automatically.

Chapter 12 · Apple Legacy Contact — Posthumous iCloud Access

Apple Legacy Contact, released in iOS 15.2 in December 2021, has become the OS-level standard for digital legacy. While alive a user designates up to five "legacy contacts." After death they can submit an access key plus a death certificate to access iCloud photos, messages, notes, mail, and more.

  • Settings location — Settings, Apple ID, Password and Security, Legacy Contact (iOS 15.2+ / macOS 12.1+).
  • Accessible data — iCloud Photos, Messages (including iMessage), Mail, Notes, Calendar, Files, Contacts, Safari bookmarks.
  • Inaccessible data — Apple Pay, iTunes / Apple Music purchase history, Keychain passwords (per Apple policy).
  • Required documents — access key (QR code plus a long ID), death certificate PDF.

Apple Legacy Contact's strength is that, after death, family members can access data without a separate court order. Previously Apple required a court order, leading to lawsuits like the 2017 Ellsworth case in which surviving families sued Apple.

The weakness is that Keychain (saved passwords) is not accessible — that is why a separate password manager (e.g., 1Password Family Recovery) is needed.

Chapter 13 · Google Inactive Account Manager

Google Inactive Account Manager (myaccount.google.com/inactive) launched in April 2013 as Google's digital legacy tool. While alive a user sets a trigger condition: "If my account is inactive for 3 / 6 / 12 / 18 months." When it fires up to ten designated trusted contacts are notified and can access or download the data the user selected (Gmail, Drive, Photos, YouTube, Calendar, etc.). The account itself can also be configured to delete on trigger.

  • Trigger conditions — 3 / 6 / 12 / 18 months of inactivity.
  • Notification channels — email and SMS alerts one month before trigger.
  • Shareable data — Gmail, Drive, Photos, YouTube, Calendar, Contacts, Hangouts/Chat, Location History, and roughly 30 other Google services.
  • Deletion option — automatic account deletion after trigger.

Its strength is that it works on inactivity alone, regardless of death. The catch is that death and trigger time can diverge, so for immediate access by family (in cases where Inactive Account Manager was never configured) a separate Google deceased-account request process is needed.

Chapter 14 · Facebook · Instagram · Microsoft Posthumous Policies

Facebook Legacy Contact + Memorialized Account — since 2015 Facebook has let users designate a "legacy contact." On death the family submits a death certificate, the account is converted to a memorialized state (a "Remembering" badge appears), and the legacy contact can pin posts, accept friend requests, and update the profile photo (messages remain unreadable).

Instagram memorialization — same policy as Facebook-owned. Family submits a death-reporting form, the account is memorialized. Reels and Stories stay up, but no new posts.

Microsoft Subsequent Death — Microsoft accounts (Outlook, OneDrive, Xbox, etc.) require a court order for posthumous access. Unlike Apple or Google, there is no pre-designation tool. Families submit the form at microsoft.com/concern/subsequent-death to request data deletion or a copy.

X (Twitter) — In November 2019 it announced auto-deletion of inactive accounts, then put it on hold after backlash from families of the deceased. Currently families can submit a death certificate to deactivate an account.

LinkedIn — A death-reporting form (linkedin.com/help/linkedin/ask/TS-DRM) leads to account closure or memorialization options.

Chapter 15 · Password Managers + Posthumous Access

Password managers are the gateway to every digital asset. A round-up of posthumous access features at the four major services.

1Password Family Recovery — Family plan users (USD 4.99 per month) grant master-password recovery rights to family members. 1Password itself does not know the master password, but a family member can access the vault with the Secret Key combination in an emergency. Available since 2017.

Bitwarden Emergency Access — Premium (USD 10 per year) or Family plan users designate trusted contacts. When a contact requests emergency access, the user's set wait time (e.g., 7 days, 30 days) elapses before automatic approval, or the user can immediately deny.

LastPass Emergency Access — available since 2014. A trusted contact requests emergency access, then a wait time (1 hour to 30 days) elapses for automatic approval or user rejection. Trust collapsed after LastPass's 2022 security incidents, with user churn.

Dashlane Emergency — grants a trusted contact access to all or part of the vault. Activated immediately or after a wait period.

A password manager plus a will has become the standard combination for digital legacy planning. Example: "My passwords live in 1Password and the master password is held by my trusted attorney," explicitly written into the will.

Chapter 16 · Korea — Holographic vs Notarized Will

Articles 1065-1071 of the Korean Civil Code define five forms of will.

  1. Holographic will (jaepilseong jeungseo) — the testator writes the full text, date, address, and name in their own hand, then seals it. Simplest yet most fragile — a single non-handwritten character voids it (2014 Supreme Court ruling).
  2. Recorded will — the testator records the will content, name, and date by voice, with one witness orally confirming accuracy. Rarely used.
  3. Notarized will (gongjeong jeungseo) — written before a notary in the presence of two witnesses. Most secure but costly (USD 200-1,000).
  4. Sealed will (bimil jeungseo) — a sealed will document is presented to a notary. Rarely used.
  5. Verbal emergency will (gusu jeungseo) — orally declared before two witnesses in an emergency such as illness or disaster. Court probate within seven days.

Most Korean families use either the holographic or the notarized form. The holographic is free, but disputes over authenticity arise — in a 2020 Seoul Family Court case the children of an 80-year-old argued the trembling handwriting in her holographic will was caused by writing while leaning on a cane, but handwriting analysis ultimately confirmed authenticity.

A notarized will carries lower dispute risk because the notary directly witnesses the drafting. Two witnesses are required, and presumptive heirs (children, spouse) cannot serve as witnesses.

Chapter 17 · Korea — Inheritance Tax + Gift Tax + Trusts

Korean inheritance tax uses a progressive bracket structure.

  • Tax base up to KRW 100 million — 10%
  • KRW 100 million to 500 million — 20% (progressive deduction KRW 10 million)
  • KRW 500 million to 1 billion — 30% (progressive deduction KRW 60 million)
  • KRW 1 billion to 3 billion — 40% (progressive deduction KRW 160 million)
  • Above KRW 3 billion — 50% (progressive deduction KRW 460 million)

Spousal deduction (up to KRW 3 billion), child deduction (KRW 50 million per child), and additional minor-child deductions apply. As of 2024 about 4-5% of decedents are subject to inheritance tax (higher in the Seoul metropolitan area).

Gift tax is separate from inheritance tax. Strategies to reduce inheritance tax through advance gifting are common, but gifts within 10 years of death are added back into the inheritance estate.

Yueondaeyong shintaek (will-substitute trust) is a fast-growing area in Korea in the 2020s. The settlor (decedent) transfers assets to a trust company while alive, and on death the assets transfer to pre-designated beneficiaries. Dispute risk is lower than with a will, and execution is immediate.

  • Samsung Life will-substitute trust — combines insurance and trust. The insurance proceeds become trust assets.
  • Mirae Asset Trust + KB Kookmin Bank Trust + Shinhan Bank Trust — trust arms of financial groups.
  • Hana Life + Heungkuk Life — retirement plus trust combination products.

Chapter 18 · Korea — KakaoTalk Memorial + NAVER Memorial

Korean digital legacy revolves around KakaoTalk and NAVER.

KakaoTalk memorial account — Kakao launched the "memorial profile" feature in July 2020. When a family submits a death certificate and family relations certificate to Kakao Customer Service, the user's profile is converted to memorial status and a flower icon appears in friends' lists. Messages, however, cannot be read by the family (privacy protection).

KakaoTalk message backup — if the decedent's phone can be unlocked, a chat backup can be extracted by connecting to a PC. But cloud sync requires user authentication, making family access difficult.

NAVER memorial page — NAVER has policies for deceased-user accounts across mail, blog, and cafe services. With a death certificate, a family relations certificate, and the requester's ID, the family can close the account. Blog and cafe posts can be preserved or deleted.

Samsung Galaxy Digital Legacy — Samsung announced a "Digital Legacy Contact" feature for Galaxy users in 2025. Following Apple's model, families gain access to Galaxy Cloud data after death.

Chapter 19 · Japan — The Age of Shukatsu

Shukatsu (終活) is a word first used by the weekly Shukan Asahi in 2009, meaning "activities for the end of life." From the late 2010s onward it has grown into a massive industry. As the Dankai generation (the 1947-1949 baby boomers) enters their late 70s and 80s, the Shukatsu market has exploded.

Shukatsu spans the following activities.

  • Writing an Ending Note — organizing one's life, funeral wishes, and messages to family.
  • Preparing a will — choosing among holographic, notarized, or sealed forms.
  • Pre-mortem decluttering (seizen seiri) — reducing belongings to ease the burden on family.
  • Digital remains organization — sorting out digital assets.
  • Pre-contracting a funeral — family funerals, direct cremation, scattering of ashes.
  • Grave reorganization — perpetual memorial graves, tree burials, and other new forms.

The Shukatsu Counselor Association (www.shukatsu-csl.jp) is a general incorporated association established in 2011. It certifies Shukatsu counselors, with more than 10,000 certified members active in 2024. Insurance, banking, and funeral company employees often acquire the certification as a sales tool.

Chapter 20 · Japan — Ending Notes + Wills

The Ending Note (endingu nooto) is the first step in Japanese Shukatsu. It has no legal force, but it organizes funeral, pension, banking, and digital asset information so the family can act. Major publishers print various formats — Kokuyo's "Moshimo no Toki ni Yakudatsu Note" (about USD 12) is the most famous.

Contents typically include the following.

  • Personal information (date of birth, registered domicile, My Number, insurance card numbers)
  • Family and acquaintance contact list
  • Asset list (bank, securities, real estate, insurance, pension)
  • Digital assets (SNS, email, password hints)
  • Funeral wishes
  • Medical and care directives (refusing life-sustaining treatment, etc.)
  • Messages to family

Wills (yuigon-sho) — Articles 960-984 of the Japanese Civil Code define three forms: holographic (jihitsu shoshou), notarized (kosei shoshou), and sealed (himitsu shoshou).

The 2019 Civil Code revision relaxed the requirements for holographic wills — the property inventory portion can now be PC-generated (previously every word had to be handwritten). In 2020 the Legal Affairs Bureau Holographic Will Storage System launched, allowing storage of holographic wills at the Legal Affairs Bureau (fee about 3,900 yen). A stored will does not require family-court probate after death.

Chapter 21 · Japan — Legal Inheritance Information Certification + Trust Banks

The Legal Inheritance Information Certification System went into effect in May 2017. Heirs apply once at the Legal Affairs Bureau, which then issues a "Legal Inheritance Information Diagram." This single document can be used at banks, securities firms, and the pension fund — replacing the previous burden of submitting family register copies each time.

Trust banks — the Japanese trust market, unlike the US, is dominated by trust banks.

  • Mitsubishi UFJ Trust Bank (www.tr.mufg.jp) — Japan's largest trust bank. Will trusts, education-fund-gift trusts, marriage-and-childcare-support trusts.
  • Mizuho Trust Bank (www.mizuho-tb.co.jp) — the trust arm of the Mizuho group. Similar product lineup.
  • Sumitomo Mitsui Trust Bank (www.smtb.jp) — the SMBC group.
  • Nomura Trust Bank (www.nomura-trust.co.jp) — the Nomura group.

Family trust (kazoku-shintaku) — a form made possible by the 2007 Trust Act revision. A family member (such as a child) serves as trustee to manage the parents' assets. The parents establish the trust before dementia progresses, so that asset management continues even when they lose decisional capacity. In the 2020s this has emerged as a core Shukatsu tool in Japan.

Chapter 22 · Japan — Digital Remains

Digital remains (デジタル遺品) is a uniquely Japanese term. It refers collectively to the digital assets a decedent leaves behind. The Digital Remains Research Group popularized the concept in the mid-2010s.

The digital remains industry has developed particularly strongly in Japan because of the gap between the Dankai generation's digitalization rate and their families' information awareness. It is common for parents in their late 70s to use smartphones, PCs, SNS, and online banking, while children in their late 60s do not know their passwords or accounts.

A number of specialist services have emerged.

  • Digital Remains Support Association — founded 2016. Issues certifications and publishes case studies.
  • Data Salvage, Digital Remains Research Institute — services that unlock the decedent's PC or smartphone, extract data, and close accounts on behalf of the family. About JPY 30,000-150,000 per case.
  • AOS Data + AOS Technology — a data recovery company. Provides recovery services for the deceased's mobile devices.

My Number and death linkage — in 2025 the Japanese government began studying automation of death registration through My Number. Municipal death notifications would auto-link to the pension fund, banks, and the tax bureau via My Number. Some municipalities are piloting this in 2026.

Chapter 23 · AI Inheritance Tax Calculators + Carta Estate

Tax calculation is the hardest part of estate planning.

Carta Estate Planning (www.carta.com) — Carta is the standard SaaS for private-company equity management. Since 2023 it has added an estate planning module: valuation of private equity held by startup founders, and GRAT/IDGT simulations for transferring assets into trusts.

Korean inheritance tax calculator — the National Tax Service Hometax (www.hometax.go.kr) has a "Inheritance Tax Auto-Calculation" menu. Inputting total assets, debts, and deductions produces an estimated tax. Since 2024 it supports natural-language queries via an AI chatbot.

Japanese inheritance tax simulator — offered by Mitsubishi UFJ Trust, Mizuho Trust, Rakuten Securities, and others. Inputting assets and family structure outputs estimated inheritance tax. Japan has a basic exemption (JPY 30 million plus JPY 6 million per statutory heir), so most households are exempt — as of 2024 only about 9% of decedents are taxable.

US estate tax — in 2024 the federal exemption is USD 13.61 million (individual) and USD 27.22 million (couple), with a 40% rate above that. With the TCJA sunset on January 1, 2026, the exemption is set to drop to about USD 7 million — which is why the estate planning market exploded in 2025.

Chapter 24 · Crypto Inheritance — Casa · Unchained

Crypto inheritance was a lawless zone through the 2010s. Without the private key the coins are forever locked — estimates suggest about 3.8 million Bitcoin cumulatively have been "lost or deceased" since 2013.

Casa (www.casa.io) was founded in 2019 in Colorado by Jeremy Welch. It champions self-custody plus multisig for Bitcoin and Ethereum. Casa Inheritance promises that "when you die, your family can reach your Bitcoin."

  • Casa Diamond / Platinum — 3-of-5 or 2-of-3 multisig. One key with Casa, one with the user, one with the trusted contact (the heir).
  • Death-triggered operation — if the user loses keys or dies, the heir recovers assets with their key plus the Casa key.

Unchained Capital (www.unchained.com) — founded 2017 in Austin, Texas. Bitcoin-only collaborative custody. Its Vault product is multisig-based.

Korean exchange inheritance procedures — Upbit, Bithumb, and Coinone process inheritance upon submission of a death certificate, family relations certificate, and inheritance division agreement. In a 2024 Bithumb case the heir authenticated as the decedent and themselves, and moved the assets to the heir's own account.

Chapter 25 · The Risks of AI Wills + the UPL Problem

The fast growth of DIY will SaaS comes with rising risk.

Unauthorized Practice of Law (UPL) — each US state bars non-attorneys from providing legal advice. LegalZoom, Trust & Will, and FreeWill all maintain that they are "self-help tools" and not legal advice. But if a user relies on automatically generated documents in a complex situation (multi-state real estate, private business, guardianship of minors) and a dispute follows, who bears responsibility?

The risk of AI hallucination — in 2024 the LegalZoom AI Assistant beta produced an incorrect answer that "in California a holographic will is valid without witnesses." A California holographic will is indeed valid without witnesses, but other states (e.g., New York) require two witnesses even for a holographic will. The case stemmed from the AI misidentifying the user's state of residence.

State bar association pushback — North Carolina, Missouri, Texas, and others have sued LegalZoom and similar SaaS over the years. In 2024 some states began legislative debates over "the validity of AI-drafted wills."

Korea's Attorney-at-Law Act Article 109 — bars non-attorneys from handling legal affairs. That is why US-style LegalTech adoption has been slow in Korea. The Lawtalk case is emblematic — in 2023 the Korean Bar Association disciplined attorneys who joined Lawtalk, and in 2024 the Constitutional Court ruled parts of that unconstitutional.

Chapter 26 · GDPR + Right to Be Forgotten + Estate

Article 17 of the EU GDPR codifies the "right to be forgotten." But member states differ on rights over the data of the deceased.

  • Germany — in 2018 the BGH (Federal Court of Justice) recognized inheritance of Facebook accounts. Families can access a decedent's messages.
  • France — Loi Informatique et Libertés (the 1978 law, reinforced by GDPR) allows explicit deceased-data opt-outs to be registered. Administered by CNIL (the national information liberty commission).
  • Italy — the Codice Privacy explicitly recognizes heirs' rights of access.

Korea's right to be forgotten — Korea's Personal Information Protection Act regulates rights to "correct/delete" (Articles 35-36). Since 2014 the KCC and KISA have run "online right to be forgotten" guidelines. Deletion of a decedent's digital traces is partly possible upon family request, but legal formalization remains unfinished.

Japan's right to be forgotten — Japan has no explicit right to be forgotten like the EU GDPR, but the 2017 Personal Information Protection Act revision provides partial protection for deceased data. The 2022 amendment strengthened restrictions on transfers to foreign governments.

Chapter 27 · The 2026-2030 Roadmap

Finally, the currents likely to shape 2026-2030.

  • AI hallucination liability legislation — states will legislate "who is liable when an AI-drafted will contains errors?" California and New York lead.
  • Blockchain wills — already piloted in Switzerland and parts of Estonia. Will documents anchored on a blockchain make tampering impossible.
  • VR/AR memorials — as headsets like Apple Vision Pro proliferate, "AI memorials" reconstructing a decedent's voice, photos, and video in VR will emerge. Ethical debates will follow.
  • CBDC + digital asset inheritance — once central bank digital currencies launch, posthumous access rights will be standardized through OS-level government infrastructure.
  • Japan's Dankai Shukatsu peak + Korean boomers entering — between 2025 and 2030, Japan's Dankai generation enters its 80s, and Korea's first-wave boomers (1955-1963) enter their 70s. Both markets explode simultaneously.
  • Mass-market will trusts in Korea — what is now a high-net-worth product spreads to the middle class in the late 2020s.
  • OS-level posthumous-access standardization — Apple, Google, Microsoft, and Samsung standardize posthumous-access APIs. ISO/IEC working group discussions begin (some debate in ISO/IEC JTC 1/SC 27 in 2024).

Epilogue — A Will Is Not a Document You Write "When You Die"

Whether you are reading this in your 30s or your 60s, one thing bears emphasis. A will and a digital legacy are not documents you write "when you die," but a map you leave for your family while you are alive.

In 2024 only 32% of US adults have a will. Korea and Japan are likely lower. But every one of us has the same things — 10,000 photos on a phone, family videos in the cloud, 200 accounts in a password manager, a social trace across SNS. When we vanish those vanish too, or become knots the family cannot untangle.

The good news is that in 2026 this work is done in about an hour. Thirty minutes in Trust & Will or FreeWill, five minutes to designate five Apple Legacy Contacts, five minutes to configure a Google Inactive Account Manager trigger, ten minutes for 1Password Family Recovery, and one short letter to family. About an hour total.

Your hour can save your family tens of hours.
