My mothers moved into an apt 2 years ago and due to only collecting SS and workers comp, I signed a rent guarantee for her. She was never late on her rent and has since signed a renewal lease with a rent increase for another year. Due to medical reasons, she is breaking lease early and moved into assisted living and I received an email that as guarantor I am also responsible for 2 months and penalty. I know nothing of terms of new lease and amount and was never asked to sign again. doesn't my guarantee expire with the 1 year term?
