Most official Spanish-to-English document projects start with a certified translation. Notarization is separate and should only be added when the receiving authority or instruction sheet asks for it.

Step-by-step explanation
A certified translation is a translation package with a signed statement about completeness and accuracy. A notarized translation usually means a notarial act is added to a signature or statement. Those are different things, and the receiving organization should decide whether notarization is necessary.
Example: if a Spanish birth certificate will be submitted with a USCIS filing, start by checking the USCIS translation rule and the form instructions. If a school, court or employer will receive it, confirm that organization's instruction sheet before adding notarization.
Write down the organization that will receive the English version, such as USCIS, a university, a court, an evaluator or an employer.
Original example: "This Mexican birth certificate will go to USCIS with an adjustment filing."Official document translations normally need all visible headings, entries, seals, stamps, signatures and legible notes handled, not just a summary.
Original example: a stamp marked "Registro Civil" should be represented in English instead of ignored.For official use, certification is often the relevant translation format because it states the translation is complete and accurate to the translator's ability.
Original example: "Please include certification because the school asked for a certified English translation."Notarization should not be assumed. Add it only when the receiving authority, court instruction, school policy or customer's attorney asks for it.
Original example: "The court clerk said the certification signature must be notarized."Digital delivery may be enough for some submissions. Printed copies, courier, notarization coordination or bundled packets should be scoped before work begins.
Original example: "Email the PDF first, then quote two printed certified copies."Decision table
