If I die, my family can use my death certificate to rescue all my money from bank and appropriate all my posses.

But not bitcoin, I was thinking about how to leave bitcoins as inheritence in a safe way, minimizing risks of be stolen by my own family (still if I trust my family, they can store improperly the keys and be stolen, or forced to deliver).

The perfect solution, in my opinion, is a mechanism whithout intervention that reveal my keys to my family, this could be done if I do not access some service for a month, or if I don't store some stuff in the blockchain for a month or ... I don't know a solution. And only my family could access my keys, possibly they have keys that allow then to access my keys.

An good solution could be some artifact, like a file, that I can send to my family, or left it stored online and thar artifact could reveal my keys only to my family.

My basic ideia is:
1 - Encript the keys with your password, but must be a very strong password, resilient to brute force atack.
2 - Print the encripted keys in paper or some more durable medium and store securely in your home.
3 - Reveal to your family a limited set of characters with wich they can sucefuly find the password using brute force, in a short time.
4 - If you die, your family must get into your home/safe box, get the encripted keys and use the characters to perform a brute force atack in order to get the keys.

Does anyone have think about leaving bitcoin as inheritance? Is there already some solution to this? Thoughts?
