New rider, how to prevent being sued in case of any injuries?

I'm looking for a rider to take care of my horses while I'm in college. So what should I give him to sign, that he won't be able to sue me if he falls down, gets bitten, etc, etc... well if all things that could happen while being in my horses company happen?

Do you mean something like a duty of care form. You could always google something and change it around and have him sign it.

As you are not in the UK or the US I doubt anyone here can help you.

However under most European law a disclaimer is not worth the paper it is written on.

You are best consulting a lawyer who has experiance with equine cases, or failing that talk to your insurance company.
