There are so many topics on inheritance plans in this forum, so anyone who is looking for an inheritance plan that aligns with them simply has to use the search button and read these discussions that we have had over the years.

However, i want to add that if you do not have anyone you trust, i recommend that you keep your seed phrase to yourself. For me the option of a lawyer is an emphatical NO. Take note that even if you have a trusted family person, they may not understand anything about BTC, they could have a terrible opsec, so if you give such a person access to your seed phrase, you are very close to losing it.
