UPDATE:
Talked to a solicitor today and showed them all my documentation and polices' etc
Turns out I AM / WAS covered on DH's car - NO OFFENCE COMMITED, terms of my insurance means that the fact that DH's policy had lapsed had nothing to do with the fact that I WAS COVERED.
The police, it turns out, in the words of my new hero, the solicitor were talking 'utter baloney'.
Apparently this is their most common cock up with car insurance and it always gets thrown out of court.
And because I was covered, my husband has not commited any offence either, even though his policy had lapsed (reinstated now of course).
I am flipping OVERJOYED.
I have to go to police and present them with all the stuff. If they refuse to drop charges I have to go to court but solicitor says it will be thrown out and police will be liable for all costs.
So thanks so much for all those who encouraged me to seek legal advice. I had a hunch all was not right with what police said - partly because of the contradictory stuff they said.
Solicitor said it is now a fairly major problem that police have to act on vehicles that come up on database as 'uninsured' even if the driver has another policy which means that they ARE insured.
I won't fully relax until it's completely settled but I feel a lot better. So does DH.
Ironically, had his policy not lapsed, my policy would not have covered me (How weird is that?) However, had his policy not lapsed I would never have been stopped in the first place.
Queenofthenight and all the others who advised getting legal advice THANKYOU
AF - I'm still a fan of yours, but on this one you were wrong. Even if you were right about the emotional stuff.
DH is now going through all insurance policies with a fine tooth comb in slightly OCD type manner (poor sod will take a long time to recover from my wrath and the shock)
