My Partners left at the weekend. I have 3 kids under 7. I am really worried I am not going to be able to make ends meet. He has said he will pay the mortgage and some of the bills but he's so unreliable this may change after 2-3 months. I am going to apply for Tax Credits and was thinking of speaking to a solicitor about getting something in writing stating how much he's going to pay towards the bills, any advice would be appreciated.
