International laws such as Mahr agreements and the Hague Convention vary across countries. For example, the Marhr agreements, which are complicated and religious in nature, depart from standard divorce law. Child support, child custody and finances are just a few of the ways international divorces can vary across jurisdictions.
Meanwhile, expatriates and cases where each spouse is from a different country can further complicate divorce cases. In the case of expatriates, it can be hard getting the needed support and there are feelings of isolation. For cases where both spouses are from other countries, divorce law becomes even more convoluted.
