I am an adult woman in her 40's with 2 daughters and recently divorced. I am struggling financially and am considering asking my birth father for a lump sum contribution to help me. My birth father divorced my mother back in the late 70's and chose to be absent from my life. He never paid child support to my mother and I am an only child. From what I know he has property, access to his super and is well of mind and health. So I was wondering if I should persue asking him for a payment to make up for his lack of financial support while I was growing up in some way. I don't feel very comfortable about asking for money but do I have a right to request backpayment ( my mother is deceased)
