What Does a Notary Do? Making a Document Believable Elsewhere
By the BrainSnail editorial team. How these articles are written and checked, and how to tell us when one is wrong.
A signature on a document proves very little on its own, since anyone can write a name and nobody receiving the paper in another country can tell whether the signer was who they claimed or understood what they were signing. A notary exists to solve that specific problem, by creating an official record that an identified person signed a particular document on a particular day.
What the job involves
The core function is authentication, and the work is procedural rather than advisory:
- •Verifying identity from official documents, which is the central duty and the one that most disciplinary cases turn on
- •Confirming that the signer appears to understand the document and is acting voluntarily rather than under coercion
- •Witnessing the signature, which must generally happen in the notary's presence rather than being attested afterwards
- •Administering oaths and affirmations, so that a statement becomes a sworn one with penalties attached to falsehood
- •Certifying that a copy is a true copy of an original that the notary has seen
- •Recording the transaction in a register kept for years, which is what makes the act verifiable long afterwards
- •Applying a seal and signature, which is the visible mark other jurisdictions rely on
The two systems
The role differs enormously between legal traditions and the difference causes constant confusion. In civil law countries, which is most of continental Europe, Latin America and much of Asia and Africa, a notary is a highly qualified legal professional, frequently requiring a law degree and further specialist training, appointed in limited numbers, who drafts important documents including property transfers, wills, company formations and marriage contracts. A document drawn up by such a notary is an authentic act, which has special evidential force in court and can in some systems be enforced without a further judgment. In common law countries, notably the United States, the notary public is generally not a lawyer, requires only a short course and a commission, and may do nothing more than verify identity and witness signatures, with a specific prohibition on giving legal advice. English notaries occupy a middle position, being qualified lawyers, small in number and used mainly for documents destined abroad. That gap produces a recurring problem for immigrants from civil law countries, who reasonably expect a notary to provide legal help and encounter someone forbidden to give it.
How documents cross borders
The notary's seal is only the first step for anything used internationally, since an official in another country has no way to know whether a given seal is genuine. Traditionally that required legalisation, a chain of certifications in which the notary's signature is authenticated by a higher authority, then by the foreign ministry, then by the receiving country's embassy, which was slow and expensive. The Hague Apostille Convention of 1961 replaced that chain for member states with a single certificate, the apostille, issued by a designated authority in the country of origin and accepted by all other members without further steps. That is why anyone dealing with a foreign birth certificate, adoption, property purchase or company registration encounters the word. Countries outside the convention still require the full legalisation chain. Electronic notarisation and remote notarisation by video link have been adopted in many places, accelerated substantially during the pandemic, and raise their own questions about identity verification at a distance.
Why the formality matters
The apparent bureaucracy is doing work that becomes visible when it is absent. Notarial acts deter and detect fraud, particularly in property transactions, where forged transfers of title are a persistent crime and the requirement to appear in person before an official who checks identity is the main obstacle. The register creates a durable record that can be examined years later, which matters for wills and powers of attorney precisely when the person who signed can no longer confirm anything. The requirement that the signer appear in person and appear to understand is a safeguard against undue influence over elderly and vulnerable people. And in civil law systems the involvement of a trained notary in drafting means that important documents are prepared correctly the first time, which is the justification offered for the higher cost and which reduces later litigation. The corresponding criticisms are that notarial monopolies restrict competition and raise prices, that the common law version adds cost while verifying very little, and that both are being overtaken by digital identity systems that can prove who signed something more reliably than a seal can.
The takeaway
A notary creates an official record that an identified person signed a particular document voluntarily on a particular date, which is what makes the document believable to someone who was not present. Civil law notaries are specialist lawyers who draft important documents carrying special evidential force, while common law notaries public are usually not lawyers and may only verify and witness. Documents used abroad need an apostille under the 1961 Hague convention, or the older full legalisation chain.
