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.
If not for the loved ones, than for no one, basically, I would agree on that.
No need to get your hard-gained BTC's or funds to somebody that may just steal them in the end..
Keeping things in your own custody is always best thing for everyone because now trusting anyone is not helping or giving any benefit.
But still we can't live without our loved one's because they are near to us about lawyer I never trust because its never been good idea to go with anyone outside home.
