My son is recently divorced, not amicably, and has custody of his teenage daughter who resides solely with him. His ex wife was removed from the marital home by the police. The mortgage is in my sons sole name and he has always paid the mortgage by himself. Obviously because they were married some of the equity will belong to his ex. The house has been up for sale for several months, with her full knowledge and my son has just accepted an offer. His ex has told the estate agents to take the house of market. There is no financial order in place yet, mainly because she won't agree to anything. Can she stop the sale at this stage?
