Hello, I'm in a de facto relationship. I have a son from a previous relationship. Myself and my partner own one house in my name and another house in both of our names. If we don't have a will and I should pass away, who would inherit the house in my name and also my part in the other house? I'm worried that my son would not get any inheritance, so wondering what the best thing to do would be, a will? My son will turn 18 in a few weeks. Thank you very much for your help.
