Hi,
Where a couple marries or enter into a civil partnership and each partner owned a residence which the couple continue to use after the date of their marriage of civil partnership, they must nominate which residence is their joint main residence as married couples and civil partners can only have one main residence between them.
The nomination must be made within two years of the date of their marriage or civil partnership.
