Hi all, my partner recently moved in with me and last week he received a letter which was sent to his parents address from tax credits. The letter was a statement for a child/ tax credits claim in his name and his ex partners name. He split from his ex in October 2012. He assumed she would change the claim as she dealt with it all and all money went into her account. She never did and carried on claiming/ signing his signature on the renewals each year and claiming that they were both receiving benefits. As soon as my partner received the letter he rang tax credits and told them everything. They are now saying because he didn't contact tax credits when he left he is half responsible and will need to pay half of the money back. Her claim has now been cancelled and she will have to pay the other half. I can partly understand him being responsible for the claim from the time he left until the time she forged his signature to keep claiming on his behalf but surely for the rest of that period she is solely responsible? ? The stress this is causing is unbearable. We have a baby due in July. I already have two children with an ex partner who I don't receive child maintenance off as we have our own agreement that he uses that money to take them on days out and to take them shopping etc so he can enjoy his time more with our children voice versa. His ex has caused us nothing but upset. She has sent endless abusive and threatening texts. Constantly threatening to stop her ex from seeing his son and now this. Can anyone offer any advice as we just don't now where to turn. We barely manage as it is and we both work full time. Thank you in advance x
