There are many places in the legal system where a relative may be involved with your life unless you have specified who you want to act in that role. For example, if you don’t have a will, then the state has guidelines as to which relative will act as your executor. But in the case where you don’t want a certain relative to have any role or responsibility with you in any matter, can you create a single document which prohibits that person from being involved in any such way? Although creating a will, power of attorney, etc. are beneficial for this purpose, they don’t necessarily cover every case and can be cumbersome and costly to setup and maintain. It seems like it would be simpler in this kind of situation to have a single document which says a specific person should not be considered as a relative in any legal matter you are involved with.
A common use for this would be for when you have a falling out with a relative. You may be fine with any other relative taking on a legal role, but you don’t want this specific relative to be involved in any way and you don’t want them to receive any benefits from your estate. Is there anything like that?
