Legal rights of martial child, when there has been an affair
I have just learned that my father has had an affair. There is now another child due to this affair. He has bought a house that the other woman lives in. She only pays rent. My mother told me that the rest of the mortgage has to be paid in 7 years time. The other woman does not have the financial means to pay this off as she lives on benefits paid to her by the government. So it looks like the debt will have to be paid by myself and my mother. What legal rights do I have over this property? If I have to put money towards it does the mother of the other child or the other child have any rights? As I don't want to lose out financially.
