My neighbor does odd jobs for me such as taking out the trash, cleaning out the gutters, etc. They fell off a ladder and required medical attention. Recently, they received a letter from their insurance provider that states:
If another person or entity caused or may be responsible for the injury/illness treated, we have processed the claim in accordance with your contract benefits. However, we may be able to recover the expense of these services from the party causing the injury. Before we can close this matter, we require additional information from you.
Are they obligated to respond? If so, how should they respond?
