I have been through the divorce and financial and my ex is entitled to 33% of the profits from the sale of the house. I have had 3 estate agents to value the property and have written to my ex twice to tell me which estate agent to use. He has not replied, and I have spoken to his solicitor and they have not had instructions from him. How can I sell the house without his say so? I need to sell to pay off debts as soon as I can and I think he knows that.
