Hi. My child's father has agreed to make a lump sum child maintenance payment. There is no court order, it is voluntary. He never took paternity and refuses to sign a private agreement confirming the money is child support. It is not a stream of payments, just one lump sum.
HMRC will probably see this as income in absence of any proof and tax. What can I do? Has anybody experienced a similar situation? Would a self-declaration by myself be acceptable to HMRC? Is there anything else I can do to keep this money for my daughter as tax free?
Thanks in advance to all who can advise.
