Entering premises with verbal permission

[Jake Thompson]

So I made a bad decision to rent to family. My sister in law has been renting from my wife and I. She lives in one unit of a duplex with roommates and we live next door in the other. We have been going into each other's homes since we bought the place. We go over there for holiday meals or for parties and she comes over to our house as well. We've always been welcome at her house. Recently though, she has done a 180 and stopped paying rent and is now saying we entered her home illegally. We are filing an eviction for not paying rent but I'm curious if she has any legal grounds. We have always been invited in by either her or her roommates and she's never complained about it until now. In fact we have talked to her many times about not just walking into our house and first knocking and waiting for us to come to the door, if we aren't busy. Yet she still walks right in.
