Insurance fraud - is the joint signatory (?) liable?

[captainbluebear]

Just a quick one. I did a search but couldn't find the answer, so here goes.

If a couple take out joint house insurance and one of them files a claim (a very large claim) that is fraudulent, can the other person named on the insurance be held accountable?
The other person may have known about the claim but there was nothing they could do to stop it as there was DV in the relationship.
What are the implications if this is found out and investigated?
Cheers.

I think they make out a joint payment on any claim, so yes, in accepting it you are participating in a fraud.

Hmmmmm.... so even if the other person didn't know or didn't agree with it and would have been at risk, they could and probably would be held accountable. Do you think this would be the case if other counts of fraud were found out during an investigation even if the other person had no knowledge of them?

What if for example, an expensive item of electrical equipment had two claims made on it, one on a house policy and the other on a business policy, by the same signatory? Needless to say the original equipment was actually fine and is still in use today.
The money gained was not used to replace like for like in either case, and the person who signed for the claims is the only person who benefitted from the payout.
What do you reckon would be the outcome then? Would that be civil or criminal?
Cheers

Did the other party know about this?

Not until well after the event. Basically the person who made the claim bragged about it to someone else and then the other person named on the insurance found out.
Like I say there was DV in the relationship so there was definitely one person in charge with the other just having to do what they were told or in this case, not being told!
The really big claim that I first mentioned was known about by the other (non signing) party but they could do nothing as it would have been more than their safety was worth at the time.
