My husband and I cosigned a rental agreement with our daughter and husband in July 2019. In January 2020, daughter and husband entered a lease purchase with this same landlord, without my husband or me as cosigner. Doesn't the new lease purchase agreement cancel out the old rental agreement? The land lord is trying to hold my husband and me liable since we were on the original rental contract. She is continuing to contact me about issues with the house. (termite bond, etc.)
