I’m currently in a joint mortgage with my exP. I pay the entire mortgage; he contributes nothing. I’m on a variable rate and he’s refusing to allow me to apply for a fixed rate as he wants me and small dd to sell up and get out. Am I allowed to apply for a fixed rate deal by myself or do I need his permission/signature? To clarify, this has been going on for years; I cannot afford to buy him out and not enough equity to sell and start again. I’m managing the mortgage just about at present. Advice would be fab, thank you.
