When does our liability start/stop with regard to damage caused to a neighbour's property?

A ball which came from my house ended up in our neighbour's gutter (we don't know how it got there.) The guttering over-flowed and they claim it has cause significant damage to their property. I'd be grateful if anyone could advise where our liability starts/stops (our insurance company isn't prepared to pay out.) Thanks.

In the US, if it can be proven that the ball ended up in the gutter because you were negligent in some way, you can be liable for all "foreseeable" damages.

Negligent is not the same thing as intentional.

Just because something is accidental, doesn't mean it isn't negligent. For example, if you are obeying all traffic laws and there is nothing you can reasonably do to avoid an accident, you are not negligent. But if you "accidently" hit someone while applying mascara as you drive, you are negligent.

So if a ball landing on a gutter is a reasonable, ordinary result of playing with the ball, and its landing on the gutter could not have been avoided by taking reasonable precaution--no negligence.

But you can see where the argument will lie.

Once you have been found negligent, you are responsible only for damages that are reasonably foreseeable, not for damages that are so far out there that no one could have imagined them occurring.

But I would guess most courts would find that a ball in a gutter can be reasonably expected to clog a gutter and cause damage.

On the other hand, the neighbor is required to "mitigate" damages. They might have avoided this if they regularly inspected and cleaned their gutters. They might have avoided more extensive damage if they investigated at the first sign of trouble instead of waiting for more time to pass. (An example.)

Turn the matter over to your homeowner's insurance company and let them defend you. Sounds like you will need a defense.


(Gee wiz, I'm surprised to be disagreeing with you here!)

in the UK following the chain of causation law of tort you would probably considered liable.
however, if the ball got there by an act of nature - ie it blew over there then you would not be considered liable.
moreover, if you have reasonable fencing between your property then you may be able to argue that you had made sufficient precautions to prevent such occurrences - but this would depend on the height of the fence, or if there is one at all.

The law of tit for tat is the one you should be most concerned with. If you believe it is a genuine complaint, from a genuine neighbour, then you have an obligation to play fair.

If you believe your neighbour is a chancer, then call their bluff.

You will find out where your legal liability rests when no legal claim comes your way.

However, your lack of moral obligation might result in ill will and potentially worse than that retaliation.

If the ball was thrown into the gutter then you could be held liable for any damage caused. Best course of action is to try and negotiate a settlement with your neighbour. It depends on how much damage was caused. If he has to claim from his own insurance then you could offer to pay any excess.

I think where a ball lands is more an act of God. You shouldn't have to pay for that. That's like saying the leaves from your trees clogged his gutters and you're responsible.

In the US, lacking an intent, it's an accident and you probably aren't liable in most courts
