回复：Thanks! She only paid me 1mth1wk rent since Jan 1st,she claim

status of limitation is referring to the time period that she can suit you. If the status of limitation is 12 months. That means she can suit you within the 12 months after she moved out. That is what you need to be sure keep 100% documents.

If she said that, put it in writing and have her initial each lines to make sure that she is aware of that.

Indeed if she is a B+++h, she might still hunt you and you might need a TPO down the road. So far dont worry about it right now.
