Nm, you edited.

But I still wouldn't go with that in this instance. The reason for the "rental" scenario is to avoid being common law/essentially a pre-nup. In your example it's limited to family members, etc. kind of tough to have it both ways.

I wouldn't want to tell revenue Canada that you're "renting" her part of the place to avoid being common law, but you're avoiding claiming it as rent too.

Either way out of scope. Off to PM.
