I went for getting birth certificate. Not much rush. If documents are ok they will collect documents and will issue the certificate next day. Take all original and photo copy of the documents in order to avoid wasting time.
For Birth certificate, 58 AED for Arabic or English birth certificate for both 116 AED, Need to bring your original passports, marriage certificate, EID, Birth Notification from hospital Original, took 1 to 2 hours to receive New Birth Certificate.
Helpful staff.
Customer service is pretty good.
