The incident took place more than 6 months ago but my insurance company have only recently been in touch with me. When asked over the phone I said that I didn't recall an incident (which was actually true as I was unsure about the dates given the passage of time). I have not reported the incident to anybody.
I have not lied. I have only said on the phone with the insurance company that I did not recall the incident as they were very vague with details. There has been nothing at all in writing. I only ask this because it seems underhand for the other party to make a claim after agreeing not to at the scene, so I wonder whether they should be made to prove that the incident took place. I'm not actively trying to shirk my responsibilities.
OK, thanks for clarifying the issue of my ignorance! I will speak to the investigator today with regard to my version of events.
With regard to the other party's version of events, how much grey area is there likely to be? Is there anything I need to be alert to? What are the likely scenarios where I could be held at fault or even 50/50?
