How do I evict someone who is not on my lease that I've rented my?
Wow, that is very specific. A few things before we get to the point: Even if they are not on your lease, by taking money from them in exchange for the room, you've likely created a tenancy at will. You may be in violation of your lease because of this situation, putting you at risk of eviction. The issue here is that you really should speak to a qualified attorney to help on this. Landlord/tenant law is very jurisdiction specific and fairly detailed. No one here can really give you on-point advice without many, many more details. You'll likely have to seek an eviction order to get rid of your tenant which can be costly and time consuming. Make sure you are aware of your jurisdictions laws on this: hire an attorney.
