my daughter filed and received a divorce from her spouse. part of the decree was that she received the house. later, she sold the house and moved. the mortgage company settled the account and sent her a check for the balance in the account. the mortgage company addressed the letter to my daughter whos name included her maiden name and married last name. they also showed the ex's name. the window enevelope was not big enough to show her full name and only her maiden name showed through. since this occurred, the post office had no forwarding address for this so they sent the letter to her ex. he cashed the check(remember, his name was on the check)even though he knew the money did not belong to him and now refuses to pay it back. without resorting to filing suit in court to get the divorce decree enforced and have the money returned that way, is there any criminal charges applicable for this misappropriation of funds?
