You won’t need to apostille any document for Guatemala, since that country is not member of the Hague Convention.
Anyway, Guatemala has special requirements for “embassy legalization” and here you will find some steps to legalize your documents.
Any document presented in Guatemala Embassy or Consulate office will have to be first certified by the State.
Documents should also be certified by the U.S. State Department in Washington, D.C. if required.
Some documents like “power of attorney” requires notarization prior to being presented to the Embassy or Consulate.
Apostilleworld offers apostille and /or legalization services for the Embassy of Guatemala.
