Has anyone written down their Crypto instructions and given it to a trusted family member in case something happens to you?

I don't mean to be morbid or anything, but people have wills, life insurance policies, etc and are supposed to have their ducks in a row in case something unexpected happens to them. I wouldn't want my crypto funds to just vanish without my family knowing how to access them, so I intend to write up instructions on how to access wallets, what is in them, etc. These directions would of course be stored in a safe alongside other important documents like passports, birth certificates, and the hard wallet seed phrase. I'm wondering if this is a good idea and if other people are doing things like this - just in case… appreciate any input.
