I rented property with an individual who ended up being mental unstable and yelled at me in front of my children about something which we had a verbal agreement on (witnessed by at least three individuals), and began to make demands on me regarding how things on the property would be carried out. Our landlord stated that he would let one of us out of the lease and sign a new lease with the remaining person, so I gave my 30 day notice. I paid last months rent upfront, and he is now stating that he is going to keep the prorated amount (last day is Dec 12th) if she is unable to cover the rent or find a new roommate. Legally can he hold my funds (if was well known that we split everything equally) because she is unable to pay rent? What if she can't cover January, does that make me liable?
