My partner is on his ex wives mortgage, no money is being paid but he stayed as a signatory to enable her to keep the house as they wouldn’t let her keep it on her money alone, he was trying to do the right thing to ensure his children had a roof over their heads. They are all adults with their own homes and families now and we want to move forward as a couple with our own home, currently renting. He now needs to come off it, does anyone know roughly how long this takes? She also had a new partner so he can help her financially now if necessary.
