If the country where you intend to use your legal documents is NOT  a member of the Hague Convention, you will need an Embassy Legalization.

Embassy (Consular) Legalization" of official documents is a procedure of confirmation of the validity of originals of official documents or certification of authenticity of signatures of the officials, authorized to certify the signatures on documents, and also the validity of prints of stamps, seals by which the document is fastened.

The documents for non Hague Countries are subjected to "chain authentication" in the State, Federal and Embassy levels. The Department of State, Authentications Office is responsible for signing and issuing certificates under the Seal of the U.S. Department of Sate providing authentication services on documents that will be used overseas and then they are certified in the Embassy or Consulate of that country for which they will be legalized..It take much longer to process an Embassy Legalization and it could take up to 7 days.
