I am on tier 2 sponsorship visa with dependant on me, he got new passport last year around this time. I just realised he didnot update about this police, he was 4 months out of the UK - we totally forgot

We are close to depressed now as we are eligible for ILR next year what could you advise? Will he get his ILR refused? Shall he go to police station and update info after 1 year?
Many thanks
