Divorce (U.S. citizen living in UK)

Apologies if this is not the right forum.

After 6 years of marriage, my wife and I have very amicably decided to call it quits. It's a sad thing indeed and we worked hard to try to save the marriage all last summer but we just couldn't. We separated and moved out of our flat in December. 

We married in the US (in Michigan) in 2008, moved immediately to the uk and I have my ILR. She's British and Im American.

What is the protocol here? We have no kids, property or assets to split so it should be very straightforward. I know it's tricky divorcing in the uk due to their not being an option for irreconcilable differences. Which is easier to settle the divorce in, the UK or the US?

Thanks for any advice / help given.

It is probably easier and cheaper to get your divorce in England, especially if there are no children and no contentious property issues. Start here: https://www.gov.uk/divorce

One of my children was married in Scotland to a Scottish lass who divorced him in New York after he finished paying for her medical school. He remarried in England an American (divorce decrees from only certain states, including New York, are accepted here; there are other steps to take to get "unrecognised per se" decrees accepted) who got a Visitor for Marriage visa. (They now live happily in California with their kids, but that's not relevant to this posting.)

So: don't worry about the cross-border documentation. Do what is easiest for you.
