legal implications of sleeping with roommate

need some advice...I am a 35 yr old male, and own my own home and recently started renting to 2 roommates, 1 girl - 28, 1 guy 25. Both have rental agreements, and I provide rental receipts each month to them. I started seeing and sleeping with the girl for about a month now (shortly after she moved in) and want to know the legal implications for commonlaw, as well as if Im in trouble from a landlord legal issue, say if we break up and she is still under my roof, can she claim commonlaw still after 6 months, even after we have broken up?? Or if we break up and she moves out, can she come after me for a landlord legal issue?? Just want to know what I have gotten myself into....I am in Calgary, ALberta Canada.

This really is not a LL issue. I don't know the legal statutes of marriage in Canada. Most states in the U.S. no longer recognize common-law marriages. There are still palimony issues and such here, but no recognition of a live-in situation as a marriage. I suggest you research this under the on-line statutes for your area of your country.

As for the LL issue from this situation, if you have written agreements with both tenants, write receipts and require both tenants to continue to pay you rent (which I suggest you do - don't let her stop paying rent), and you continue to enforce her agreement clauses, she would still remain a tenant (although I think the slang term would be "with benefits".) If you break up, and she is on a month to month agreement (which would be a good idea), you can ask her to leave by giving her the required notice. If she fails to leave within the time limit on the proper notice, you can evict for holding over the agreement as long as you no longer accept rent.

This really is not a good idea. But since you are already into the situation, continue to enforce the agreement as stated for both tenants to appear to be fair and non-discriminatory. How does the other guy feel about this? (Like a third wheel?)
