Two years ago we moved into a rental house. We signed a two year lease and paid the security deposit like we were supposed to. The landlord at the time did not inform us that she was in a legal battle with her brother for ownership of the property. After a year we were informed by the landlord's brother that he now had legal custody of the property. He informed us that he was raising the rent and he wants a security deposit as well. My question is do I legally have to pay another deposit? He made me sign a new lease even though the old lease had time left on it.
