Hi I've been living with my boyfriend for 2 years but we file our taxes separately. We don't want to file as common law because I think it is a disadvantage when it comes to paying taxes. Now we want to buy property together (so far we've been renting) but I'm worried if we do that somehow the government will find out and "force" us to file as commonlaw. How can I avoid this happening? I've heard something about being tenants in common rather than having a joint mortgage. Also, if we open a joint bank account to pay the mortgage will the goverment know?
