The Cover Letter they use to process this request is linked at the box below for your convenience.
***Attention*** The Cover Letter (linked below) says that birth certificates need to be certified by the County Clerk or local registrar where the birth occurred. So, when you call to order your birth corticates, ask them how you get this local County Clerk certification? Tell them you need this for international adoption from a Hague Country.
