Last but not least anyone requiring any kind of legal assistance in Qatar please refer to the designated lawyers list published on the US embassy web side

I warmly recommend Law Office of Noora Sarhan to anyone bear in mind those guys charge quite a bit.
...sure never saw a lawyer who refuses to take my money...
Though it might be hard in the ME to find a judge ruling against the national pride...
You might have realized that Qatar is a big country with a huge number of locals
Better make sure first who is who and who hates whom and who is married with whom and ....still, the lawyer won't refuse your money, but in a country like Qatar he will barely make a difference! If you seek justice, better do it in a civilized country...
