Certified Copy vs Notarised Copy — What's the Difference?

Two levels of document authentication — understanding which one you need.

When someone asks you for a "certified copy" or a "notarised copy" of a document, you may assume they mean the same thing. They do not. While both confirm that a copy matches the original, they carry different levels of authority and are produced by different professionals. This guide explains the differences and helps you determine which one you need.

Why Does the Distinction Matter?

The distinction matters because the requesting party — whether a foreign authority, employer, university, or government body — may specify one or the other. Providing the wrong type could mean your application is rejected or delayed. Understanding the difference saves time and money.

What Is a Certified Copy?

A certified copy is a photocopy of an original document that has been compared to the original and stamped or signed by an authorised person confirming it is a "true copy of the original."

  • Who can certify: A solicitor, Commissioner for Oaths, Notary Public, Garda (in some cases), or other authorised person (depending on the requirements).
  • Authority: Has domestic authority. The certifier is confirming they have seen the original and the copy is accurate.
  • International use: A certified copy from a solicitor or Commissioner for Oaths is generally not sufficient for international use unless specifically accepted by the foreign authority.
  • Cost: Typically the less expensive option.

What Is a Notarised Copy?

A notarised copy is a photocopy that has been certified by a Notary Public, who compares the copy to the original, confirms its accuracy, and attaches a notarial certificate with their official seal and signature.

  • Who can notarise: Only a Notary Public.
  • Authority: Has both domestic and international authority. The notary's seal is recognised worldwide.
  • International use: A notarised copy is required when the document is for use abroad — visa applications, foreign universities, overseas employers, embassy requirements, etc.
  • Apostille: A notarised copy can be apostilled by the Department of Foreign Affairs for use in Hague Convention countries. A standard certified copy cannot.
  • Cost: Typically more expensive than a standard certified copy, reflecting the additional authority and formality.

Key Differences

  • Professional: Certified = various professionals. Notarised = Notary Public only.
  • Seal: Certified = stamp or signature. Notarised = official notary seal + signature + notarial certificate.
  • International recognition: Certified = domestic only. Notarised = international.
  • Apostille: Certified = cannot be apostilled. Notarised = can be apostilled.
  • Cost: Certified = lower. Notarised = higher.
  • Formality: Certified = simpler process. Notarised = more formal with identity verification.

Which Do You Need?

A Certified Copy Is Usually Sufficient For:

  • Domestic applications (Irish government, Revenue, employers)
  • Situations where the requesting party says "certified copy" without specifying notarisation
  • Internal company records

You Need a Notarised Copy When:

  • The document is for use abroad
  • The requesting party specifically asks for "notarised" or "notarial" certification
  • The document needs an apostille
  • An embassy or consulate requires it
  • A foreign university, employer, or authority requires it
