My daughter's fourteen year relationship ended in January when her partner left her and the two children. They agreed that, rather than pay maintenence, he would pay the mortgage and the fuel bills for the time being. Since then he has been living with his parents. She applied for and received Single Parent Working Tax Credit. She says that there is nowhere on the application form to declare the financial arrangement, but she did bring it up in one of the conversations, and was told that it made no difference. She also applied for and received council tax single occupancy discount.
