What documents to carry when entering uk on spouse visa?

Hi

My wife will shortly be entering the UK on an indirect flight from India on a spouse visa.

My question is what documents should she carry with her in case she is stopped and questioned? eg marriage certificate etc.

Can anyone offer any insight?

Much appreciated.

She may also want to carry, in her hand luggage, a recent chest X-ray or an acceptable medical certificate certifying that she is free of TB. Else, if she is not pregnant, she may be subjected to a X-ray examination at the airport.

If you do not have enough items in your joint names, you may provide items addressed to each of you individually if they show the same address and you provide roughly the same number for each of you.
