Bitcoin inheritance is a technical problem, not just a legal one. These are the best tools, wallets, attorneys, and protocols for making sure your heirs can access your stack — without compromising your security while you're alive.
You've spent years accumulating bitcoin, securing it in cold storage, guarding your seed phrases like state secrets. You've done everything right.
And then you die, and nobody knows where to find anything.
Bitcoin inheritance is genuinely hard. Unlike a bank account, there's no customer service number your spouse can call. No probate court subpoena will magically unlock a hardware wallet. If your heirs don't have the keys — or the instructions to use them — your bitcoin is gone forever.
The challenge: you need to make your bitcoin accessible to trusted heirs after you die, while keeping it fully secure against theft while you're alive. These are nearly opposite requirements, and solving both is what makes bitcoin inheritance planning unique.
This guide covers the best tools, protocols, attorneys, and hardware designed specifically for this problem in 2026.
For the conceptual framework and legal context, see our full Bitcoin Inheritance Planning guide.
Any inheritance setup has to solve a fundamental tension:
The best inheritance solutions create a structure where:
There are three main approaches: multisig with time-locks, legal/attorney-based planning, and custodial inheritance services.
Casa is the gold standard for managed bitcoin inheritance. They offer a full multisig custody service with a dedicated "inheritance protocol" — a structured process that activates after death verification.
How it works: Casa manages one key in a multisig arrangement. Your heirs contact Casa, provide a death certificate, and go through a verification process. Casa then co-signs to help your heirs access the funds.
Casa handles both the technical setup and the human process — including walking heirs through the recovery steps even if they've never used bitcoin before. Their concierge service includes setup calls, document templates, and support for executors.
Who it's for: Bitcoin holders with $50K+ in BTC who want a professional, guided inheritance process without DIY complexity. Casa's annual fee is significant, but for serious wealth it's justified.
Liana by Wizardsardine is an open-source Bitcoin wallet built specifically around inheritance and recovery use cases. It uses Miniscript to create spending policies with timelocks — you hold the primary key, and your heir's key becomes valid only after a certain time passes without you "refreshing" it.
The mechanic: every 6 months (or whatever period you choose), you sign a transaction that resets the timelock. If you die and stop refreshing, the timelock eventually expires and your heir's key becomes active.
This is pure trustless inheritance — no third party, no custodian, no attorney required. Just Bitcoin's scripting language doing exactly what you set up.
Who it's for: Technical bitcoin users comfortable with multisig who want a fully self-sovereign inheritance solution without relying on any service provider.
What to know: Requires more technical setup than managed solutions. Your heir needs to understand the recovery process. Excellent for people who want no single point of failure and no dependency on companies that could go bankrupt.
Nunchuk is a multisig wallet platform with inheritance features built in. You can set up a multisig scheme with different keys held by trusted family members, attorneys, or friends — and define quorum rules that activate differently for spending vs. inheritance scenarios.
Nunchuk supports PSBT (Partially Signed Bitcoin Transactions) across devices, making it practical to involve multiple signers who aren't technically sophisticated. Their platform also includes a "collaborative multisig" feature designed to make the signing process understandable for non-technical heirs.
Who it's for: Families who want to involve multiple trusted parties in custody, with the inheritance process being a collaborative unlock rather than a solo action.
Cypherock X1 is a hardware wallet designed around the concept of splitting your seed phrase across multiple physical cards (using Shamir's Secret Sharing). Instead of one piece of paper with 24 words, you get 4 cards — and any 2 of 4 can reconstruct the key.
This is particularly useful for inheritance: give one card to your spouse, one to a trusted family member, keep two yourself. Any two can recover the wallet. A single card alone is worthless to a thief.
Who it's for: HODLers who want physical redundancy for inheritance without complex software. A good complement to any multisig setup.
Empowered Law is Pamela Morgan's consulting practice. Morgan is the author of "Cryptoasset Inheritance Planning" — the most widely recommended book on the subject — and has been consulting on bitcoin inheritance since 2014.
Her framework centers on creating a "Sweet Sixteen" document: a complete, clear inheritance letter that guides an executor through recovering your bitcoin even if they know nothing about crypto. Templates, legal frameworks, and professional consultation services are available.
Who it's for: Anyone who wants to create a complete inheritance letter and legal framework, with guidance from the person who wrote the book on this subject (literally).
Jeff Vandrew Jr. is one of the few attorneys in the US who specializes specifically in bitcoin estate planning. He combines legal expertise (trusts, estate law, probate) with deep bitcoin technical knowledge — meaning he won't just draft a generic "digital assets" clause, he'll actually structure custody arrangements that work for the bitcoin specifics.
Key services include: bitcoin-specific trusts, executor instructions that account for multisig and hardware wallets, and legal structures that minimize probate exposure for crypto assets.
Who it's for: US-based bitcoin holders with significant wealth who want proper legal documentation alongside the technical setup — wills, trusts, and executor instructions written by someone who actually understands bitcoin custody.
BitGo Trust offers institutional inheritance services for large bitcoin holders. As a regulated trust company, BitGo can serve as trustee or custodian for bitcoin held in trust structures — with proper legal documentation, regulated oversight, and institutional-grade security.
This is appropriate for estate planning involving $1M+ in bitcoin where you want the legal protections of a trust structure with a regulated custodian.
Who it's for: High-net-worth individuals and family offices structuring bitcoin within a formal trust.
Anchorage Digital is a federally chartered bank that offers estate planning services for digital assets. As a fully regulated institution, Anchorage can be named as custodian in a trust or estate plan — providing the legal standing and regulatory protection that comes with a national bank charter.
Who it's for: Institutions and ultra-high-net-worth individuals who want regulated bank-level custody integrated with estate planning.
Regardless of which tools you use, a complete bitcoin inheritance plan needs to answer these questions:
Your heir needs an inventory: which wallets, which exchanges, which custodians, and roughly how much at each. Without this starting point, they won't know what to look for.
For each holding, document:
List trusted contacts: your attorney, a technical advisor, any service like Casa that has a co-signing role. Include account numbers and reference details.
If bitcoin is held in a trust, your executor needs the trust documentation. If there's a will, it needs to reference digital assets properly. Consider state-level laws on digital assets — many US states have enacted the RUFADAA (Revised Uniform Fiduciary Access to Digital Assets Act).
Do your heirs know where the inheritance documents are? Have you walked through the process with them? A plan nobody can find is not a plan.
One specific challenge: how do you give someone the information they need to recover bitcoin without giving them the ability to steal it while you're alive?
The cleanest solutions:
A single document with your full seed phrase, sitting in a safe, is a convenient theft vector if anyone ever gains access. The goal is splitting knowledge so no one person has everything they need — except upon your death, when the threshold is met.
Can I just write my seed phrase in my will? No. Wills become public documents when probated. Writing your seed phrase in a will is broadcasting it to anyone who files a public records request. Use a private letter held by an attorney, or a technical solution like the ones above.
What happens to bitcoin in a trust? It depends on the trust structure and trustee. A properly drafted trust with a bitcoin-capable trustee (like BitGo or Anchorage) can hold and distribute BTC according to your instructions. A generic trust with a bank trustee who doesn't understand bitcoin is a problem — many traditional trustees will simply liquidate to cash.
Do I need an attorney? For larger holdings, yes. A bitcoin-knowledgeable attorney like Jeff Vandrew Jr. can ensure your estate plan is legally sound — not just technically functional. The two requirements (legal validity + technical recoverability) need to be solved together.
What if my heir is not technical? Choose solutions that include non-technical walkthrough support: Casa's concierge service, Pamela Morgan's inheritance letter format, or an attorney-as-executor setup. The technical complexity should be on your side (during setup), not your heir's side (during recovery).
Bitcoin inheritance is a solved problem — but it requires deliberate setup. The biggest risk is not doing anything.
