The current issue of The Economist has an interesting article on international divorce law, the introduction to which is as follows:

MARRIAGE may be about love, but divorce is a business. For global couples—born in different countries, married in a third, now working somewhere else and with children, pensions and other assets sprinkled over the world—a contested divorce is bliss for lawyers and a nightmare for others.

Divorce laws vary wildly, from countries (such as Malta) that still forbid it to Islamic states where—for the husband, at least—it may be obtained in minutes. Rules on the division of property and future financial obligations vary hugely too. France expects the poorer party, usually the wife, to start fending for herself almost immediately; England and some American states insist on lifelong support. Some systems look only at the “acquest” (assets built during the marriage); others count the lot. A few, like Austria, still link cash to blame (eg, for adultery). Japan offers a temptingly quick cheap break, but—for foreigners—little or no enforceable contact with the kids thereafter, notes Jeremy Morley, a New York-based “international divorce strategist”. Other places may be mum-friendly when it comes to money but dad-friendly on child custody.
