Last friday I had to stand in front of a judge and say that two people where not living together for the last year so they could get a divorce in the state of Virginia. After 6 months of marriage it took a year, a judge, an attorney, and a witness, plus some cash to finally separate them.
If they had been married for 10 years then there would be Social Security implications etc. Plus I think they still force you to take a blood test ect.
PS: Separation of Church and State my ass.
