I'm the owner of our matrimonial home but my ex does not want to give consent to put house on sale. We had domestic situation where police was involved due to his abusive behaviour. He does not want to move out of house either. To protect child's interest I make the decesion to move out with my son in a few months. We haven't finalized separation agreement. Can you forsee any potential issues with that in case he refuse to take over and pay mortgage? Can I stop monthly mortgage payments and what are the consequencies?
