I see on [bitaddress] you can generate a split wallet. That's where multiple parties have to each submit their "share" keys to generate the combined private key.
So the hard part, the math, has already been done.
But, I'd like a system that has the following advantages if possible:
- No lawyers / legal contract required
- No trust required among the heirs
- If an heir dies after me but before the distribution, the surviving heirs can divide the inheritance equally
- While I'm alive I can freely use my bitcoin, and move it around, without worrying very much or at all that my heirs won't be able to find it
- My heirs can't see my private keys while I'm alive
- Non-heirs can't ever see my private keys
- My heirs can find what they need to get started after I'm gone, without too much trouble
It's probably going to have to be a combination of a physical safe, a physical key, and the online stuff and software.
I'm willing to make the assumption that my heirs will know beforehand how to initiate the process with the physical key, and that they aren't going to take their inheritance early by force (e.g., breaking into my house).
I'm also willing to use a dead man switch website. That might be like an email that I must respond to every month or else it emails all of them their keys / instructions. Note I don't know what that website might be.
Has anyone thought through a process? Even a different process that doesn't have all the advantages I'm looking for might give me ideas.
