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.
And there's no blood test in VA anymore (nor DC for that matter).
It's one thing to have both people say we agree to split property like this it's another to say you have to wait and jump though a lot of hoops to get divorced.
Consider two people that want a divorce, but can't really afford separate households at this point and don't want to sell the house when the economy is bad. Granted this is not the "normal" path but plenty of people get divorced without hating each other.
Keep in mind that with things like divorce and child custody/support, couples change their minds (sometimes a lot). Our court systems can't handle this (certainly not the costs). Over the years, our societies have required legislatures to define rules and processes for lumping everyone into a process. I don't think the state really wants to be involved in divorce cases, but there are reasons they are (property, debts, retirement benefits, child custody/support, etc).
Like it or not, state courts have to be involved in divorces. For some couples that can handle it without the courts, well, like education, they get dragged down into the mean.
Seems more like a contract between you and your spouse that has been approved of by the state.
