Hoping someone might be able to give advice. We're hugely lucky and have a big garden. A local group of homeschoolers are desperate for use of some outside space for a couple of hours a week to teach kids to grow veggies and let them build dens etc. Practically we could accommodate cars, let them have an area of space etc without us really noticing. Hubby is worried that we'd be liable if a kid got injured etc. Do we need to cover ourselves legally in any way? I was thinking I'd ask for names and addresses of all attending, which will be same group each week. And ask them to sign a basic waiver type thing that basically says sites not been risk assessed they use it at own risk. Would that be sufficient?
