In August 2003 my parked car, was hit by a boat being hand-towed at the time by its owner on its trailer. About £500 damage.
We exchanged names and addresses, and I also cross-checked his address with the launch facility - albeit I bet they were breaking some data protection act in helping me out on that one! I also got a 3rd party witness who I gather has responded in my favour.
Crucially I didn't get either his boat or car insurance details - seemed a bit overkill when the guy was all wet-suited up etc.
All my car insurance company (Frizzell) will do is write letter after letter to him - but he hasn't responded to any - even though my insurance company also believes his address checks out as valid. That's as far as they will go; they won't begin any court procedings etc for me. On the basis that it's not cost effective for them to do so!
One thing they did say is that they would have more of a lever on this guy if I'd also noted his car registration - which I'd obviously also try and do next time.
The lessons - make sure you get *all* the details at the time - I almost wish I'd also called the police. And don't respond to letters from insurance companies if you're the guilty party!
And I really must get around to checking out the small claims process for bringing a private case - I think it's a 2 year limit which is running out fast.
