Thank you both. I should have been more clear. I'm asking about a situation where you spend a couple weeks/months in their home and they stay in your home. It's not for everyone...
We have a home with a swimming pool that's easily accessible from multiple rooms. We plan to do a home exchange (swap) with a family with a 6-year-old. Are we liable if the child has a pool accident (or worse)? Is there some type of waiver we should ask the family to sign?
