My ex and I were together 8 years. When we met, she moved in to my property, signed a tenancy agreement and told centrelink she was single and renting to get more centrelink payments. Now we are separated, does the fact she signed a tenancy agreement mean anything? She was paying a nominal amount of rent, $60/week. Can she still make a claim on my property? I don't have any savings, so if that were the case I would be forced to sell my property.
