There are problems with the solution that people suggest which involve handing over keys, seed phrases etc. to your beneficiaries.

To be clear, you shouldn't give your beneficiaries or lawyers access to your wallets.

Why?

First, most people do not have good security practices. We might have but our beneficiaries do not, so there is a risk of loss or theft once they have it.

Secondly, there is a risk that they may have a gambling or drug problem. Or someone in their life who convinces them to take it now. Or the lawyer you get to hold the keys - takes the coin.
