Legally, Yes. Your homeowners insurance should cover something like that. We actually had an experience where there were several kids playing at my friends house and my child threw a stone and hit one of the other children (not one of the friends whose house we were at) and she had to have stiches. Even though it wasn't her children involved because it was on her property, she could have been forced to pay the medical bills. Thankfully the three of us mothers have enough commen sense to know that things happen like that with children and nobody sued anyone.

It depends on whether your negligence caused the harm. How old are these kids? If they are young it is likely that your failure to supervise would be negligence. Thus, the answer is you could be depending on the facts.

You are responsible for any tort on your own property. This includes any act involving adults, children, animals and property and personal injuries.

Ok question... what if they are just kids about the neighborhood does that matter (basically you didn't invite them)? (just curious)

Not if both children mistakenly fall down a very,very deep abandoned well never to be seen again:)

The reply depends on so many factors: -severity of injury (and or cost of medical claim) -if it is worth placing claim against house insurence as this can increase you rate. -is the property fenced and gated or open to wanderers -age of children involved -what level of access the child had to your property (guest paying for services, invited guest, contractor, and least of all, trespasser -if there was negligence of any parties to supervise children. I am sure more factors that can limit your liability to the child not mentioned above, but in a court it is not a clear cut yes or no, they tend to award percentages of liability **eg:** If the children were invited guests and you were actively supervising them, but unable to stop the attack then your liability would most likely be split between the attacking child's parents and yourself. If the child trespassed onto your property and was not being supervised by his parent'sand subsequently attacked by another trespasser also cutting through your yard, the liability would be split between their parents and you would not have to pay. If two were invited guests and the child attacked was an unsupervised trespaser, as you were having tea with attacker's mom.. all three parents may have to split liability to different degrees. (this is based on my knowledge of canadian business and contract law, as watching another's child is an informal contract)
