My boyfriend's father passed and the will was never updated after he married. Everything was left to my boyfriend in the will, but since he married after she is entitled to 1/3 of everything and he gets 2/3. But, if the will disappears, she gets half. She used his mentally ill grandpa to get into the safety deposit box to get to the will. The lawyer who wrote it doesn't have a copy anymore. What can he do to make sure she doesn't destroy the will to get more money (she has a history of stealing and things like this)?
