My sister was in charge of a trust fund for her 3 sons and my son. She took it and opened a shop which went bankrupt and my son has never seen his share which would be about $40,000. My uncle is very ill and has been given 1 month. In his will she will receive an amount of about $75,000. My question is, can we get a lawyer to put a stop on her getting this money until she reimburses my son and he gets his share or would we have to get a judge to do this?
