It seems that you mostly understood what I was saying, yet the way that you summarize what I said likely needs some clarification.  So, it seems that I was describing a context in which the heirs might lack some technical expertise in terms of figuring out where the coins might be held and/or the various ways to access the bitcoin - especially if there might have had been some technical issues or even problems figuring out what the deceased bitcoin holder was attempting to communicate to his/her heirs.

So there could be a variety of ways in which a deceased bitcoin holder might attempt to set things up prior to his/her death that might involve instructions and also it might involve a list of technical experts (or even businesses) who the deceased person trusts will charge a fair price in order to help the heirs without being a dishonest actor (and sure these things cannot be 100% known, but it is possible that the deceased person may know some people who he believes would be helpful and may even get paid to help.. and such persons do not need to be hackers, but surely having some decently high level technical skills might not hurt when it comes to figuring out something like putting together all the keys or maybe even getting into the deceased persons personal computer and other devices in which some contemporary files and communications and even accounts might be better found out.  We could have several kinds of accounts and there could be traces of those accounts in our e-mails or in our webpage histories, and sometimes family members might not have enough understanding to even realize that the deceased person had 10-20 different accounts and various kinds of wallets that had bitcoins and maybe shitcoins and some other digital assets on them... that could add up to hundreds of thousands or even millions that the dumb heirs might not have had known or been able to figure out on their own and without the help of the bitcoin (or crypto) technical expert (who you referred to as a hacker).

You have a point but I disagree with you on the aspect you mentioned that what if a man could not get a lawyer, I don't really no if you meant getting a good lawyer or affording a lawyer, which ever way you meant, I no most lawyer are not trustworthy but there are also good ones that can handle your will very well, so let's not reason it only in one angle, if I most say there are so many people that has family lawyers which they trust very well, most times people are always the cause of there problem choosing a random lawyer whom they don't no too well and a last either the lawyer scam them or tamper with their will and at last we generalize it to all the lawyers forgetting that in most cases we are actually the cause.

In times of willing Bitcoin to our children one could actually open each Bitcoin accounts for each of the children instead of sharing from one centered account because you don't no if some would like to hold there Bitcoin for something there.
