I am hiring a live-in nanny. Actually I am exchanging free rent in exchange for child care. Is this person my nanny or my roommate? If anything goes wrong can I just terminate the person? My biggest concern would be if they get mail at my house would they be entitled to "squatter's rights" Would I have to evict them? I live in Georgia.

A nanny is an employee, whether paid in cash or bartered. When employment ends then have to leave.

OK so I need to write up an employment contract? I have tried to find contracts or some type of model on the internet and everything is either vague or you have to pay over a $100 for it. If it was your home what course of actions would you take to ultimately protect your assets and family.

Keep it simple. State the names of the parties and what each one brings to the contract.
