There is an administrator and if they write to the administrator saying I don’t want my bit, that should be all there is to it.
Great Aunt Mary dies intestate and all the great nieces and nephews inherit, all 50 of them get €2K each and I am living in the US and it is just too much hassle so I disclaim. Then the 49 left get a little extra each.
Who is going to object or say it wasn’t right? The 49 others or me in the US in a years time when I really need €2K. If I sue the administrator they have the letter?
I would say it would be problematic if I said I don’t want my 2K, give it to my brother John instead. If I was the administrator I would say no to that. Just tell me to gift it to John myself after I get it from the estate.
Looking at small amounts like above makes it simple it is when the money gets bigger, say €100K each that things get more fraught, but the same principles apply.
