Bitcoin Inheritance Planning

What Happens to Your Bitcoin If Something Happens to You?

This is the topic nobody wants to think about, but everyone needs to plan for. What happens to your Bitcoin if you are in an accident, become incapacitated, or pass away? Unlike a bank account, there is no automatic transfer, no next-of-kin process, and no court order that can recover Bitcoin if the keys are lost.

An estimated 3-4 million Bitcoin are permanently lost — many because the holder passed away without leaving access instructions. That is over $100 billion in value, gone forever. Do not let your Bitcoin become part of that statistic.

The Problem: Security vs Accessibility

Here is the paradox of Bitcoin inheritance:

• Good security means nobody can access your Bitcoin except you
• Good inheritance planning means someone you trust can access your Bitcoin if you cannot

These two goals seem to contradict each other. The art of inheritance planning is finding a balance — giving trusted people just enough information to recover your Bitcoin, but not so much that they (or an attacker) can steal it while you are alive.

Method 1: The Sealed Letter Approach (Simple)

This is the simplest method and works well for beginners:

1. Write a detailed letter explaining:
   • What Bitcoin is and that you own some
   • Where your hardware wallet is stored
   • Where your seed phrase backup is stored
   • Step-by-step instructions for recovering the Bitcoin (assume the reader knows nothing about crypto)
   • A recommendation to seek help from a trusted crypto-savvy person if needed
2. Seal the letter in an envelope
3. Store it with your will or in a bank locker
4. Tell one or two trusted people that this letter exists and where to find it

Pros: Simple, low-tech, easy to set up

Cons: Anyone who finds the letter can access your Bitcoin. The letter could be lost or destroyed.

Method 2: Split Seed Phrase (Intermediate)

For better security, you can split your seed phrase across multiple locations:

1. Take your 24-word seed phrase
2. Split it into multiple parts — for example:
   • Part A: Words 1-12 (stored with your lawyer or in a bank locker)
   • Part B: Words 13-24 (stored at home in a safe)
   • Part C: A complete backup (stored with a trusted family member in a sealed envelope)
3. Leave instructions so your beneficiary knows to combine both parts

Pros: No single location has the complete seed phrase

Cons: If one part is lost and you do not have a complete backup, your Bitcoin is gone. Also, note that splitting a seed phrase can actually reduce security in some scenarios — a 12-word portion is easier to brute-force than a full 24 words.

Method 3: Multisig (Advanced)

Multisig (multi-signature) is the most technically robust inheritance solution. A multisig wallet requires multiple keys to authorize a transaction. A common setup is "2-of-3," meaning any 2 out of 3 keys can move the Bitcoin.

Example setup:

• Key 1: Your personal Ledger (kept by you)
• Key 2: A second Ledger stored in a bank locker (accessible by your spouse with proper identification)
• Key 3: Held by a trusted third party (a lawyer, a family member, or a professional custodian service)

In daily use, you use Key 1 + Key 2 to move your Bitcoin. If something happens to you, your spouse can use Key 2 + Key 3.

Pros: Extremely secure. No single point of failure. Can be set up so no one person (except you) can move the Bitcoin alone.

Cons: Complex to set up and manage. Requires technical knowledge. If you lose access to 2 out of 3 keys, the Bitcoin is lost.

Practical Tips for Sri Lankan Context

• Bank lockers — Sri Lankan banks offer safe deposit boxes. These are excellent for storing seed phrase backups or a sealed inheritance letter. The cost is typically LKR 2,000-10,000 per year depending on the bank and size.
• Attorney letters — consider having your inheritance instructions held by a lawyer as part of your estate plan. Some lawyers in Colombo are becoming familiar with crypto assets.
• Cultural considerations — in Sri Lankan families, discussing inheritance and death can be uncomfortable. But this conversation is necessary. You do not need to share amounts — just that you have crypto assets and there is a plan.
• Update regularly — if you change wallets, create new accounts, or change security setups, update your inheritance plan accordingly.

The Bottom Line

The best inheritance plan is one that actually exists. Even the simple sealed letter approach is infinitely better than no plan at all. Do not procrastinate on this. Set up at least a basic plan today.
