Same-sex marriage occurs every day in the United States, but only in states where it has been legalized. Every business day, same-sex couples are issued marriage licenses somewhere in the United States. The numbers are certain to increase as more states legalize such marriages. Significant legal developments on the federal level are certain to occur sometime between March 26 and June 30, 2013, as the United States Supreme Court decides the constitutionality of California's Proposition 8 and the Defense of Marriage Act.
What happens in the first night of marriage stays in the first night of marriage!
New Marriage Law happened in 1950.
All remaining U.S. states and territories are now close to legalizing same-sex marriage by judicial action. This is expected to happen nationwide before July 1, 2015.
Abstinence. That's what.
"Marriage. Marriage is what brings us together...today."
I don't believe there is anything in the US Constitution about marriage.
In places where it has been legalized, it happens exactly the same way as any other marriage (i.e., apply for marriage license, ceremony before authorized officiant, registration of marriage, issuance of certificate). In places where it has not been legalized, it does not happen except symbolically.
No it is not a valid license. However, a properly executed marriage in Scotland will be legally recognized in the US with a Certificate of Marriage from Scotland.
If the marriage was legal where it was performed, the US will recognize it as a legal marriage, with the responsibilities and obligations expected.
As regards What?
it doesnt happen...
It apparently became unconstitutional when the first same-sex couple married and were denied some federal benefit. On June 26, 2013, the US Supreme Court ruled that Section 3 of the Defense of Marriage Act ("DOMA") was unconstitutional.
