I found an interesting forum post at on a different website saying
"I hate posting half a story, but we know a non muslim, UK couple who have married under Sharria Law.
Apprantly it's a civil ceremony, not binding and not recognised aywhere outside the UAE. just provides them the neccesary documents they needed.
Whilst I know sharia courts will try non muslims, I was previously unaware they married them!! However, whilst this isn't first hand experience, I am assured this is the case, and this "sharia married" couple seem to have no problem going about their business in Abu Dhabi, and have secured residency and sponsorship, without any apparant problem.
Might be worth looking into?"
I have looked everywhere for this non binding document, because my GF & I are both moving to Abu Dhabi, both are sponsored by our employers. We do not wish to get married, but this is something we'd definitely be interested in because we'd like to live together legally.
Could someone please make my day by shining a little light on this subject.
If it helps I'm Australian & she's Canadian
thank you
