If his name is on the mortgage- it's his as well as hers.
My partner's going through this **** at the moment too- although she's been separated from him for about a year & a half- his name's still on the mortgage, and can't get him off it for another 2 months, when the bank lets her sign it over into a sole ownership.
They wouldn't let her sign it over into her own name straight away, since she needs to prove to them she is capable of paying the entire mortgage by herself, with no late payments etc for 18 months total (Despite the fact she'd been paying it all by herself since the mortgage started!!)
And the solicitor said- They would rather have 2 people to chase up for the debts, rather than just one. That way they have more chance of recovering their money.
The difference being in her situation though- her ex has never paid a penny towards the mortgage, since he's a lazy **** and done nothing but sit around the house smoking weed.
It came down to the point where I told my partner to stop paying any more of the mortgage as she was paying all of it, yet he was still entitled to half of the property.
Not only that, but because the mortgage was being paid by direct debit from a joint account- when she was puting funds into the account to pay the mortgage- he was taking them out and spending it on beer/ weed!
Anyway- The arrears went to about £4,000 on the house, and he maxed out the overdraft on the joint account to about £2,500, and about 5 months later, the bank was ready to take action on repossessing the property- so we went to the solicitors, and got some kind of legal document drawn up (I forget what it's called now but can find out for you if you wish).
The document basically said that- Katie (My partner) would pay the arrears off in full by herself, AND pay the full mortgage payment each month for the next 18 months- THEN, he would sign the mortgage over to Katie as sole owner of the house.
He was a **** about it at first, but we gave him an ultimatum:
He signs the document, and gets nothing in return.
OR
He doesn't sign the document, the house is repossessed, and both Katie AND him are chased for the debt for years to come- probably forcing them both to go bankrupt. BUT- Me and Katie would move abroad, leaving HIM to take full responsibility of the debt.
So... that's the bitch of a time we've been having this last year. I wanted to burn down the Halifax, and knock **** out of her ex, but that would of left a huge debt- So we played it cool. Soon as he's signed the mortgage over- We're going to **** on him from a height!!
Not sure if that's any use to you.
