Unfortunately for you if the co-owner (partner) in the home that you own has invited the daughter that was evicted previously to move back into the same unit that the eviction arose from, the invitation is allowed and the evicted person may legally move back.The rationale is that one owner of the unit can act on behalf of both. Such essentially is the cornerstone of basic partnership law.What you have is a problem between you and your wife/partner caving in to your detriment and most likely hers. I suggest that you and your wife have a face to face talk about the realities of what she is doing and undoing all that was done in getting the difficult child out of the "nest".
