My partner split with his ex 2 years ago, he pays the full mortgage and £200 a month for his 12 year old son, who he doesn't see because of the mother as she a looney! she has a partner who lives at the property also, she has stated when the house has to sell she will smash it all up so no one gets anything? please any advice on this, should he stop paying the mortgage? were going through the courts regarding access but she is dragging it out, please help
