I have had de facto partner for the last few years (we met in 2007). I have 2 children (now in their early 20s) from a 20yr marriage which ended in 2006. My de facto had a child about 17 years ago. He only lived with the mother for a few months, was lied to about contraception etc at the time and had no future living with this woman. He has paid some minimal child support. My question is: if he dies, is his child entitled to any of his or my property? Are children automatically entitled to your property if you die? Can this be determined in a will or agreement between myself and him? We just want to get some wills sorted but need to consider what rights children have.
