I am the personal representative for my mother's estate. Her home is currently for sale and furniture has been left for "staging" purposes as well as some of my personal property for the same reasons. My sibling removed a set of keys to the property without asking. I believe I am responsible for the keys and the fob which opens her secure building and is owned by the senior cooperative where she lived. Do I have the right to request their return? Also, managing her estate is very time consuming and involves some minor expenses. While I am handling this because it was my mother's request, is it possible to be compensated for this?
