@jonri -
My H is a trust and estates/elder lawyer and I am also an attorney, but not in that field, although I have worked on many cases with him. He has videotaped will execution ceremonies on several occasions, although I will agree that it’s not always necessary or warranted. The purpose is to demonstrate that the person is not under duress and has testamentary capacity, which is a lower standard than regular competency. Although the tape isn’t admissible to show competency, it can demonstrate, for instance, that the person is neat and clean, can speak clearly and understands both the natural objects of their bounty and the nature and extent of their estate. In one tape that my husband made, the client pointed out a typo in the will and it was changed The client also discussed why he did his bequests the way he did. When the attorney for the relative who had been cut out of the will saw the tape, he convinced his client to drop the challenge because it was clear that the testator was acting of his own volition and knew what he was doing. The challenge was going to be based on undue influence allegedly exerted by another relative and it wouldn’t have stood up.
I don’t think you can blanket say never videotape or always videotape. Like any other estate plan tool, a determination as to the propriety and need of a particular device has to be made on a case by case basis.
About your point #2 - that is an excellent observation. Hopefully, the OP has her plan in place as well. Since she has siblings, perhaps one of them should be designated as a successor POA for the mom.
The joint account is the easiest means for using the money on a day to day basis to cover bills. If there’s a concern that the OP would inherit too much money on her own if she gets any remaining proceeds for herself, the family could agree to fund the joint account with only as much money as is needed for day to day expenses.
I think that the initial question raised in this post is an important one. It’s useful on the other end as well. I had to get my young adult children to agree to let me access their school records and their health insurance records as well. H and I have discussed getting POA’s from them and I think we will pursue it. Once they marry, their spouses can assume that function.
