I have received a letter from HMRC regarding an over payment of tax credits from 4 years ago. This was an old claim with my ex husband, at the time my claim immediately changed to a single claim.Any apparent over payment would have been paid to him as the sole earner, I was a SAHM. I called tax credits saying surely I should only need to pay half the balance as it was a joint claim, they said no. They will chase us both for the full balance until it is clear, whoever first.
Ex dp has refused to pay anything towards it, so it's all left to me. Does anyone know what the law is on this? They have also requested the balance in full, nearly 1k.
