Technically speaking you can get divorced in any country where you are resident and do it in the local courts where resident. I used to live in HK and everyone is an expat there and there are all sorts of expats filing for divorce there with no connection to HK other than one of both parties was then resident there. They are all expat marriages - like maybe an American who may have married a Swiss in Barbados while they were living in Toronto and now one lives in Mexico and the other is concurrently resident in HK and Dubai but spends all their time as a tourist in Thailand. Where to get divorced? The general rules is that either party can file for divorce where that party is officially resident and do so in the local court and then that local court can decide to try to apply either their local laws or the laws where most appropriate. It’s called forum shopping. I’m a citizen of 3 countries, and so was my ex, of 2 different countries, we together lived in 6 other countries over the years, never having anything resembling a “home country,” and we got married on holiday in a totally unrelated country, and my ex did exactly that, and my lawyers did the same.
