Well, let's say you have 6 Bitcoins in your Wallet and you also have 3 kids, so perhaps you wish to give 2 bitcoins to each of your children. When you feel you are getting older, and by then your children might have also come of age, you can discuss with them how you want to will 2 bitcoins to each of them, but they can only access them (the Bitcoins) when you have passed on. Then, you can have your private key or wallet phrase divided into four different places and hidden in four different locations (the fourth location is where you will hide the hardware wallet and the last phrase or last key to access the wallet) . then inform each of your kids about the location where he or she can find a piece of the private key, so that when you have finally passed on, the three kids can come together with each piece of the private key so they can combine it together before they can be able to access the location where you have hidden the hardware wallet and the last key to unlock the wallet.


Sometimes, human beings can just feel biassed and do otherwise when the willer has passed on. I remember a movie where a rich man willed his property to his children, but after the man passed away, the wife connived with the law and made the lawyer have some properties willed to her, and the lawyer also took some shares in the property. Some people can be trusted, but In your absence, they can just go against your will.
