How to change sponsor's address

My overseas partner is applying for fiancee visa to marry me and reside with me in the UK.

I reside in a flat that I own. I'm looking to move to a house and let out the flat.

The visa sponsorship form (https://assets.publishing.service.gov.u ... p-form.pdf) asks 'Full Postal Address where the Sponsored Person will be residing in the UK'.

The visa address change form is only for migrant who is already in the UK visa-address-update.service.gov.uk. How can we update the address if it changes during her application or before she arrives in the UK please?

The SU07 sponsorship form is NOT required for a spouse visa. You do not have to complete this form at all.
