My ex partner and I were together for 5 years and have a 4 year old son. Just last year we bought a house. Only his name is on the mortgage, and he is the only one who has contributed financially to the mortgage, as I have been a stay at home mom caring for our child. He says that since he is the only one who has contributed to the mortgage that the house is his. I know that this is true for a common law relationship without a child, but when a child is involved is it different?
