Hi, yes of course. I sent the following, all covering the full 14 years we have been together.
Marriage certificate
Children's birth certificates
Joint mortgage agreements and statements for both properties we own and letters from solicitor referencing the purchase of each property
Joint bank statements
Joint credit card statements
Car insurance documents showing both as named drivers
Council tax bills in both names
Home insurance policy in both names
Statements for the property we rent out in both names
Life insurance documents in both names
Holiday details, booking details and boarding passes
Photos of us as a couple and as a family over many years
Letter of support from family
I also included a covering letter which detailed a time line of our relationship and when we would be arriving in NZ and what our plans would be.
Good luck!
