Hi, We have a few caregivers who come help with my mom and 100-year-old grandmother's activities of daily living. They are paid cash, don't have a contract, don't hold any certifications or training for this work. Where can I get a waiver of liability, for them to sign, in case they were to hurt themselves on the property / job, e.g. helping Grandma? We have great relationships with these people, they are clearly here by choice, and are almost like family, but you never know what can shift in a person when they get hurt or feel they have been wronged in some way, and know that the family has money they could go after to feel compensated. Thank you.
