Owning a house as joint tenants with my ex and mortgage on both names. I divorced and moved out last year. Consent orders were made to sell the house before June 2020. This has lapsed now and the other party is not willing to sell. Who pays the mortgage now ? Can I refuse to pay now, given that I was supposed to be no longer owning my share of the house and bound to a mortgage ? Child support payments are agency collected, ex has the means to pay the mortgage.
