Hi,(posted 7169 days ago)As you have already admitted liability by paying I would suggest that you try and negotiate a settlement. Have you got equity in your house and if so how much because you really do not want them to put a charge for the whole amount on the property - when and if you do sell it they will then get that chunk. Try and get into a discussion about settlement, if they insist you fill in an Income and Expenditure form make sure you show them how little money you have, indeed if you can get the form to put you into overdraft land even better. Secondly your ex cannot stop paying maintenance just because he has 2 children with his new partner. Get in touch with the CSA as you cannot shirk your responsibilities. My husband has a fruitcake of an ex wife who has stopped him seeing the children altogether and he still pays £300 a month for them - and we don't begrudge the children one penny as he is still their father.
