Crypto and incapacity: plan ahead

Incapacity (illness, accident, cognitive decline) can arrive before death. A will does not help then: while you are alive but unable to act, the relevant legal instruments are powers of attorney and similar arrangements, and they rarely mention crypto. A little planning closes the gap.

The problem

• Your crypto is protected by secrets only you know. If you cannot communicate, nobody can act, not your family, not your lawyer.
• Banks and exchanges may freeze or restrict accounts when notified of incapacity proceedings.
• Self-custody crypto has no customer-service route at all.

The legal instruments

A durable power of attorney (or the local equivalent, such as a living will arrangement, an enduring power of attorney or a notarial mandate) names a person who may handle your affairs while you are alive but unable to act. Its scope is yours to define: personal matters only, finances only, or also digital and crypto matters. Where no such document exists, a court may appoint a guardian or administrator. Either way, this gives legal authority but still no technical access.

Crucially: legal authority gives no automatic technical access. The authorised person has the power, but without the right passwords, keys or device access they still cannot use the wallet. The technical side must be prepared separately, while you can still decide.

What the plan must contain

1. A trusted person with legal authority. A durable power of attorney (or the local equivalent) that explicitly covers digital assets and crypto. Rules differ by country, have it reviewed locally.
2. A map, not the keys. Documents that say what exists, where, and how access material is stored, never the seed phrases or passwords themselves. The map goes where the trusted person can reach it; the secrets stay in their safe place.
3. A continuity plan for self-custody. Hardware wallets, multisig setups and password managers need a handover mechanism that works before death, for example a sealed, separately stored copy, or a trustee arrangement.
4. Named fallbacks. If the first person cannot act, who else? Update the plan when relationships or assets change.

The three layers, again

Incapacity planning uses the same structure as inheritance planning:

1. Inventory, what may exist and where an authorised person can find it;
2. access instructions, how to approach a wallet or platform within the lawful framework;
3. secrets, seed phrases, private keys, passwords and PINs, kept separate and secured, with agreed rules on who may use them and when.

Lay down the first two layers and agree who may use the third under which conditions. Never place full secrets in a power of attorney, will, email, cloud document or form.

What to avoid

• Writing the secrets down in the plan. A document that contains seed phrases is a theft target, not a plan.
• A single point of failure. One password, one device, one person who “knows everything”.
• Doing nothing because it feels morbid. The plan is for your benefit: it is how you stay in control of your own assets for as long as you need.

After the plan

Incapacity planning and inheritance planning overlap. The map you build here is the same map your executor needs later, see crypto inheritance planning and crypto in a will.
