Can i let a 17 year old live with me without legal guardianship

They can allow her to live with you. You should check with an attorney in OH to see what type of paperwork is needed for medical consents and anything she needs for being enrolled in school, or for traveling. Those would be your main concerns.

This has nothing to do with guardianships. The girl's parents can consent to this arrangement. In days gone by, their agreeing for her to live in your home and share lodging with your son, or your providing such an opportunity, would have been considered "contributing to the delinquency of a minor." I don't think it is a problem today, but you may wish to check with a family law or criminal law attorney to make certain you cannot be found liable if she were to become pregnant or suffer any other difficulties.

You should get a power of attorney over a minor from the parents. You wouldn't need to go to court for that but you would at least have proof of their consent if something were to happen. Good luck.
