You can divide your private key or seed phrase into several parts and distribute them to relatives, so that only when they come together they can get access to the wallet.
It is very true that the method is very good by dividing some of the seeds of savings to the nearest person very efficiently so that it is easy to keep the wallet alive. \basically we will bequeath all to our family or descendants for a good future, and crypto in my opinion in the future be an asset or a savings, to keep that trust the wallet to the closest person who can be trusted or team.
