Documents that commonly require notarization include powers of attorney, affidavits, certified copies of identity documents, immigration letters, property agreements, and academic certificates. NotaryPublic24 provides online notarization for all these document types, with delivery within 24 hours and no in-person appointment required.
Intro
Not every document needs to be notarized – but many do, and understanding what documents need to be notarized can save significant time and prevent costly rejections. The rule of thumb is straightforward: if a government agency, court, bank, employer, or foreign authority requires verified proof that a document is genuine and its signer is who they claim to be, notarization is likely required.
This guide covers the most common documents that need notarization, explains when an Apostille is also needed for international use, and shows how to get any document certified quickly through NotaryPublic24’s online notarization service.
What Is Document Notarization?
Document notarization is the process by which a qualified Notary Public verifies the identity of the person signing a document, witnesses the signature, and certifies that the document is authentic. The notary applies their official seal and countersignature to confirm this.
Notarization does not validate the truth of the document’s content – it confirms who signed it and that the signature is genuine. This distinction matters: a notarized affidavit, for example, is still the signer’s own statement; the notary simply confirms the signature is authentic.
For documents intended for use in another country, notarization is typically the first step. Depending on the destination, an Apostille or full diplomatic legalization may also be required – see NotaryPublic24’s Apostille service for the next step in the process.
Personal and Identity Documents
Certified Copies of Passports and Identity Documents
A Notary Public cannot notarize a passport or driving licence itself – these are government-issued originals. What they can do is certify a photocopy as a true copy of the original. This certified copy carries the notary’s seal and confirms that the copy matches the document seen by the notary.
Certified copies of passports are frequently required by banks, financial institutions, employers, and government agencies as part of identity verification processes – particularly for clients who cannot present the original in person. NotaryPublic24’s certified copies service handles this fully online.
Birth, Marriage, and Death Certificates
Original birth, marriage, and death certificates issued by a government registry are official documents in their own right. They do not usually require notarization for domestic use. However, if you are submitting a photocopy, or if the document needs to be recognized abroad, a Notary Public can certify that the copy is a true reproduction of the original.
For international use, government-issued vital records typically need an Apostille rather than (or in addition to) notarization. Documents destined for countries that have not ratified the Hague Apostille Convention may need full diplomatic legalization instead.
Deed Poll and Name Change Documents
A deed poll – the legal document used to change your name in the UK – may require notarization if it is to be recognized by a foreign authority or used internationally. Some countries require a notarized deed poll to update official records, passports, or residency documentation in their jurisdiction.
Legal Documents
Power of Attorney
A power of attorney almost always requires notarization before it is legally effective for significant financial, property, or international purposes. Banks, courts, property registrars, and government agencies will generally not accept an un-notarized power of attorney.
If the power of attorney will be used in another country, it will typically also need an Apostille – and the document may need to be translated into the local language by a certified translator. NotaryPublic24’s power of attorney notarization service covers the notarization step, and Apostille can be added to the same order.
Affidavits and Statutory Declarations
An affidavit is a written statement made under oath before a Notary Public. A statutory declaration is a written statement of fact declared before an authorized witness. Both require notarization – an affidavit because the oath must be administered by an authorized official, and a statutory declaration because the declaration must be made before a qualified witness.
These documents are used in court proceedings, immigration applications, probate processes, financial declarations, and a wide range of legal and administrative contexts. NotaryPublic24’s affidavit notarization service covers both types online.
Wills and Trusts
Wills and trusts do not always require notarization to be legally valid – requirements vary by jurisdiction. However, notarizing a will can help prevent challenges to its authenticity after death, and is required in some jurisdictions for the document to be recognized in probate proceedings. A self-proving will – notarized and signed with witnesses – is less likely to be contested.
Immigration and Visa Documents
Sponsorship and Support Letters
Immigration authorities including USCIS in the US and UK Visas and Immigration frequently require notarized support letters from petitioners, sponsors, and employers. A notarized letter confirms that the person who wrote it is who they claim to be and that the signature is genuine – giving the letter more credibility than an unverified personal statement.
Common examples include spousal visa sponsorship letters, family invitation letters, letters confirming accommodation, and employer letters confirming employment status or salary.
Consent Letters for Minor Travel
Many countries require a notarized parental consent letter when a child travels internationally without both parents or legal guardians. The letter should name the child, the accompanying adult, the destination, and the travel dates. Without it, the child may be refused boarding or entry at the border.
Residency and Employment Declarations
Residency declarations, proof of address letters, and employment verification letters are frequently required by foreign authorities as part of visa or residency applications. When issued as a notarized letter or affidavit, these documents carry greater weight than unverified personal statements.
Financial and Business Documents
Loan Agreements and Promissory Notes
Lenders – particularly in cross-border transactions – often require notarized loan agreements and promissory notes as a condition of the loan. Notarization confirms that the signatories agreed to the terms willingly and that their identities were verified, strengthening the enforceability of the agreement.
Company Documents for International Use
Companies operating internationally frequently need notarized (and sometimes apostilled) copies of incorporation documents, board resolutions, articles of association, and certificates of good standing. These are required when registering a foreign subsidiary, opening international bank accounts, or entering contracts with overseas partners.
Property Agreements and Contracts
Property purchases abroad – particularly in Spain, France, Portugal, and other EU countries – often require UK nationals to provide notarized copies of identity documents, proof of address, and authorization documents. A notarized power of attorney with an Apostille is commonly required when authorizing a local representative to sign on your behalf.
Educational and Professional Documents
Degree and Diploma Certificates
Employers, universities, and professional licensing bodies in many countries require notarized copies of degree certificates as part of employment or enrollment processes. The notarized copy confirms that the certificate shown to the notary is genuine, making it acceptable where an original cannot be submitted.
For international use, degree certificates also frequently require an Apostille. Some countries additionally require a certified translation into the local language.
Professional Qualification Certificates
Medical, legal, engineering, and other professional certificates may need notarization when seeking recognition abroad or registering with a foreign professional body. Requirements vary by country and profession – always check with the relevant licensing authority before applying.
When Notarization Is Not Enough: The Apostille Step
For documents that will be used in another country, notarization is often only the first step. If the destination country is a member of the Hague Apostille Convention, an Apostille certificate must be added to confirm the notary’s credentials to that foreign authority.
The typical process for private documents (powers of attorney, certified copies, affidavits) is: notarization first, then Apostille. For public documents (birth certificates, degree certificates issued by a government body), the Apostille can often be applied directly without prior notarization.
For countries that have not ratified the Hague Convention – including the UAE – full diplomatic legalization is required instead of an Apostille. NotaryPublic24’s Apostille and legalization service covers both routes. See also NotaryPublic24’s relocation documents guide for a breakdown by document type.

Frequently Asked Questions
What documents need to be notarized?
Documents that commonly need notarization include powers of attorney, affidavits, statutory declarations, certified copies of passports and IDs, immigration support letters, property and loan agreements, and academic certificates. The exact requirement depends on the receiving authority and the country where the document will be used.
Does a birth certificate need to be notarized?
An original birth certificate from a government registry does not need notarization for domestic use. However, a photocopy being submitted to a third party, or a certificate intended for use abroad, may need to be certified as a true copy by a Notary Public.
Do immigration documents need to be notarized?
Yes, many immigration documents require notarization – including sponsorship letters, affidavits of support, minor travel consent letters, and employment or income declarations. Requirements vary by country and visa type. Always check with the relevant embassy or immigration authority.
What is the difference between a notarized document and an Apostilled document?
