I think you'll find that the "state" doesn't want to sanction this, 'cause the insurance industry doesn't want to cover same sex partners (if they can get away with it - which they have for a long time) nor do they ("states") want to pay spousal medicaid, SS, etc. to people they have historically gotten a free ride with (anywhere between a 3% to 10% / 2 hit).

In any case, I bet it would cost the "state" lots of money, no?
