All bills at previous add were in exes name although I admit financial connection is that beyond reasonable doubt that we were co inhabiting...would it stand up in court.

Forgot to say was approx 4 years ago had wages paid in

After some advice really I'm being sent for iuc for benefit fraud. A friend of mine was initially having probs with getting bank account due to her being American,so I let her use my account ,we have now moved in together approx a year ago as couple and stupidly didn't inform dwp of change of circumstances Now worried they will have got bank statements for last 4 years and try and charge me for fraud goin back 4 years which wasn't the case. Is having wages paid in enough to convict ?
