In  EWHC 2932 (Fam) Radseresht v Radsheresht-Spain Cohen J is asked to recognise a divorce (and ensuing financial arrangements) granted under Dubai law. Postscript August 2018: see here for a recent Greek example.
I will not discuss the merits of the case (Justice Cohen does so proficiently, not just to my lay eye but I am assuming also the expert eye; he decides there was an intention to continue to stay married). Rather, the case is an interesting example to show those having to get used to conflict of laws. The High Court has no hesitation to apply Dubai law with all its in and outs (part of the judgment queries whether there were continued sexual relationships between the (ex?) spouses), in a court in London.
Of note is also that the High Court suggests that but for the very late raising of the issue, it could have queried whether the courts at Dubai had jurisdiction in the first place, habitual residence of the parties not having been at the UAE (the suggestion seems to have been made by counsel of the husband that the relevant criterion would have been nationality anyway).
