I would suggest checking this out with a good lawyer, because dividing up assets during a divorce depends on where you were married and where you divorce. Where you were married defines the laws of how your assets were allocated at the time of the marriage. For example, in the UK both partners share all their assets on the day they marry (hence the famous words in the ceremony "with all my worldly goods I thee endow...") That is not the same in all countries. In The Netherlands, partners entering a marriage do not pool resources on their wedding day. They each have ownership separately of what was theirs beforehand.

Where you get divorced will define how those (shared) assets are divided up. Again, it varies from country to country; Spain is a better place for a man to get divorced. The Netherlands has a strict formula to be applied (almost, fill in a spreadsheet) whilst the UK seems to be more flexible and one of the better places for a woman to get divorced.

If you were not married in Oz, nor have ever "set up a household" in that fair country, nor are getting divorced there now, then I see no reason that Australian jurisdiction would apply. Your passport defines your citizenship, not the laws under which you marry or divorce. If you are divorcing in Thailand, then Thai law would apply for division of assets. I don't know the set up over there, but she may have rights to assets outside of Thailand. Worth checking with a good lawyer in Thailand.

Not because I would literally be the stranger on the beach, but because I seem to have spent most of my life exploring and coming to grips with other cultures and locations.

Could be a bit too mellow, but that's a risk I'd have to take.

I'm not sure if you have already married into the family or not (maybe you are still referring to the missus as your girlfriend). If you are not married, then it seems premature to be making payments beyond the GF.

If you have married, then talk to your wife and try to find out the undercurrents inside the family. (If your family is anything like mine, that will take some time! But worth doing). At one extreme, the WG may have set the standard and the family may be expecting another 12000 from the new son-in-law. At the other end, they may feel that each part of the family does what it can to support the rest.

Either way, I would be talking to the family (and particularly the head of the family) about payments and not the WG. His payments are his business. Your payments are yours.
