Ex pays the mortgage in lieu of paying any maintenance for our 2 dc.
I came home today to a letter from the mortgage co saying he's discussed it with them and he wants to stop paying and that I need to get in touch with them so he can cancel his DD
I'm pissed off - it's the first I've heard of this, plus we are both on the mortgage so surely he can't call them to say he's not paying any more and that I must?
What can I do?
