Not sure I would go into details about your hubby's past unless asked. The point of the criminal check is to determine that you have not done something bad to a child. To say that you have had checks done on both you and your husband to show no offences against the vulnerable sector is not lying or really not leaving anything out. What someone did many years ago does not have a bearing on the current situation and most employers would look at the same report and dismiss it as not a valid concern in the workplace.

I have issues with a family that ties so much importance to the forms since they only deal with convictions and truthfully if you can give references covering a period of years without a gap then the reality is you were not charge, jailed, gone to trial or anything so the piece of paper is just that. The references they can call to do their own confirmations are more important in my opinion.
