lova...
if i remember right u asked abt notarization earlier, for which was my reply. without mentionning for what it was for. and yes, the dubai courts do all sorts of notarization, including comparison against original docs. edn certs they wont, as it requires another process, where firstly they would like to ascertain the originality of the originals.
i have no idea of the same being done by the congendia here. in my case i had got all my edn certs certified & stamped much earlier for my dubai work permit. which was done first at min.of edn-delhi, min.of hrd-delhi & uae consulate in n. delhi. and then again at the uae min.of foreign affairs in dubai. i just deposited these copies onlt to chc-london.
abt now, with new cases, i regret, i'm not aware of the process. some other members on board shall effectively address that, i guess.
hope that helps.
