Before I separated from my husband we received a letter from hmrc saying they had over paid child tax credits and we had to pay it back. My husband was out of work and we couldn't afford.
Now we've split up. I'm currently written off sick due to depression and anxiety and put in a new claim for tax credits in my name. They now want me to pay back the overpayment 
I don't know how they managed to over pay by so much, my husband must have given completely wrong estimates. They don't have his new address, so haven't asked him to pay them back, although he is working and earning.
I have no money to pay them back with. I'm struggling to make ends meet as it is.
Has anyone been in a similar situation? What will they do? I presume they're going to take my current payments away which will really hurt.
