No one has ever asked to see my marriage license except the Army, the VA and Social Security. Not the IRS, no insurance company, no bank, no school- it really is amazing that our family was on a state employee insurance policy for many years and yet they never asked for proof that we were married.
I do think Obama should be required to prove he is eligible to be President. Our Constitution has requirements spelled out for the office, and he should have to show that he meets the requirements.
IRS....when your filing as a married couple your social security numbers will do as id. Most liking you changed your maiden name.
Insurance companies and banks use driver license for ID.
When I had to use my VA educational benefits to go to school I had to show my DD-14 and my BC. Both were raised seals.
