My friend, an elderly woman of 87, is attempting to evict a tenant for breach of an implied contract. She exchanged rent for labor to remodel 2 units. The contractor has not completed the work that was agreed upon at this time. It has been 10 months and she is now trying to evict. She was forced to hire someone to complete the work. She has been deprived of rent not only for the 2 units not completed by the contractor and the unit he occupies. He is threatening to place a lien on her property. Can he do this?
