Like you say. The usual ways of handling things after you are gone. Tell your spouse and mother. Or entrust it in a sealed envelope with a lawyer. I already have "if anything should happen to me" letters, addressing other but similar issues, entrusted with a couple of close friends, which get updated every few years. If I had enough cryptocurrency to worry about this issue, I'd consider just putting the keys in those, assuming they're very close friends. If not, this situation would actually be a pretty good use scenario for a multiple signer key system. And if you're worrying about the majority of people you could trust colluding against you, you probably have bigger problems.
