Well, you can use your spouse's documents, but i must ask, Do you and your spouse share the same last name?
Yes, that's right.
Excellent, Then you can use those documents that are in your spouse's name to serve as proof.
Good, thanks. In the case i hadn't those, what else i could use?
You can use a phone bill, an electricity or gas bill, water bill or cable bill. You can even use your divorce papers.
I just thought, may i use a union card?
Sure, you can use that document, even if you no longer have that union job.
Great. I heard that the main documents needed are birth certificate or marriage record, If i don't have those, what can i do?
You can enlist the help of the NYS Department of Health Vital record to get some proof.
But if i'm not from NY, can i still use that service?
Yes, you can. That will enable you to ask for records from new york and many other states.
I f i have additional documents that proof my relationship, can i submit them?
Sure, you can do that.
You said earlier that divorce papers will work?
