My father recently married without a prenup, he divorced after a month and added my name on the deed to a rental property with right of survivorship in Oder to protect my inheritance, he is currently dating someone new and insisting I allow her to use parts of the property even after he may pass. He is threatening to take my name off the deed. Can he do that without my consent? He is suggesting duress as he entered a facility in the beginning of the divorce for a nervous breakdown?
