Is a new passport actually a 'change of circumstances'?
 

CAB told us its not a change of circumstances and the visa data is held on the BRF.

backstory:

Spring time last year, migrant spouse arrived in the UK with valid spouse visa, BRF etc.

September last year spouse had a new passport issued by their embassy.

At that time, the 'Migrant Change of circumstances form' (MCC) didnt seem to apply to their circumstances. as it had that Tier-1 to Tier 5 tick boxes, and nothing about family visas.

Also the rules (which in my opinion) are not worded clearly state MCC form should only be used if the old passport is lost or stolen. that doesnt apply to us either.

however spouse is concerned about the 1000 pound fine for any late applications which come after the 3 month period.

i'm not worried about this.

suggestions?

If you mean BRP then, no, you don’t need to inform the Home Office if you renew your passport. You simply carry your new passport with the existing BRP when you travel.
