This was years and years ago but this is what we had. I was not on any of the utilities or house. I had my husband on all medical paper work as contact person for the kids and myself, all medical insurance was through my husband's work for the kids and I, car insurance policy in both our names. DL for each of us with the same address. Vet bills with both, my pets from Canada, junk mail came in one name only but showed the same address as the other things summitted. Life insurance showing who the beneficiary is, wills, debit cards for the same account, credit cards with both listed.
