Are you saying that your wife wants to go back to the police on that original incident to make some more kind of spurious complaint or to resurrect it?
You are quite correct that the police have six months to charge you after which, it would be deemed to be abuse of process. It’s unlikely therefore that the police would resurrect this now.
It would be different if the incident was 6 months ago and she was making the complaint now but that’s not the situation., However, even in this latter situation, because the evidence is “cold” it’s most unlikely that the police would investigate much in any event.
Can I clarify anything for you?
Your understanding is absolutely correct but don’t be surprised if your wife starts making new spurious (lies!) allegations although what she would hope to gain by that you are petitioning for divorce, only she would know.
Please rate the service positive. It’s an important part of the process by which experts get paid.
