In the archive room of a notarial office, the binders carry numbers and years. Some files have not been opened in twenty years. They may be opened tomorrow, because an estate is being settled, because a sale is being challenged, because an heir wants to know what their father signed. That is where the notary's work becomes understandable: the document is not drafted for today, but for the distant day when someone will need it.
The authentic deed, an instrument apart
A contract drawn up between two people holds by virtue of their agreement. An authentic deed holds by virtue of something more: it was received by an authority that checked its legality and that attests to what happened in its presence.
The International Union of Notaries defines the notary as a legal professional and public official appointed by the State to confer authenticity on deeds and contracts contained in the documents they draw up, and to advise the persons who call upon their services.
The practical consequence is considerable. What the deed records does not have to be proved again with every challenge: the burden of contesting it shifts. The exact effects attached to that quality — evidential force, enforceability, effect against third parties — nonetheless vary between national systems, and there is no single definition valid in every country.
Public official: a delegation of authority
The phrase "public official" is not an honorific. It denotes a delegation.
The International Union of Notaries describes notaries as holders of a share of State sovereignty, which they exercise by checking the legality of the acts and matters they deal with, impartially, independently and responsibly — and outside any State hierarchy.
The position is an unusual one: the notary acts on behalf of public authority while carrying on, in most systems, an independent practice and personally bearing responsibility for what they draft. They answer for their drafting before their clients, and for legality before the State that appointed them.
Impartial between two parties, and adviser to both
This is the sharpest difference from the lawyer. A lawyer is engaged for one party; a notary receives both and takes neither side.
That impartiality is not passive neutrality. The International Union of Notaries specifies that it can also take the form of lending adequate assistance to the party in the weaker bargaining position, so as to restore a balance. In other words: explaining to whoever understands least what they are about to sign is part of the function, even if it slows the signing down.
The resulting duty to advise is one of the cores of the work. Interpreting the parties' wishes, making sure they are freely expressed, translating them into terms that will produce the intended effects, and refusing an arrangement that would not: the notary bears sole responsibility for their own draftsmanship and may accept or reject the proposals put to them.
Identity, capacity, legality: the triple check
Before receiving a deed, the notary verifies three distinct things, and the order matters.
The identity of the parties first: who is actually standing there. Then status and authority: is this person acting for themselves, as the representative of a company, as an agent, as a guardian — and does their authority cover precisely the instrument contemplated? Legality last: is what the parties want to do possible under the applicable law, and on what conditions.
The International Union of Notaries puts this check in explicit terms: verify the identities of the parties as well as their status and authority to conclude the particular deed or transaction in question, monitor its legality, while ensuring that the intentions uttered in the notary's presence are freely expressed, whatever the medium used for the deed.
Those three verifications explain delays that clients sometimes find long. They are the whole point of the deed.
The instruments of economic life
Notarial practice is not confined to estates and property sales. In many countries it reaches into the life of businesses: incorporating companies, transfers of shares, security granted to a bank, instruments subject to registration.
In the seventeen member States of the Organisation for the Harmonisation of Business Law in Africa, these operations sit within a common body of uniform acts — commercial companies and economic interest groupings, general commercial law, secured transactions, collective proceedings, arbitration and mediation among others — whose interpretation is ensured by the Common Court of Justice and Arbitration.
Here too, caution is needed about geographical reach: this law applies in its member States, not elsewhere on the continent. And which instruments must be executed before a notary is a matter for each member State's own law.
Keeping, and retrieving thirty years later
This is the invisible part of the job, and probably the most underestimated.
Receiving a deed creates a lasting obligation: keeping it, being able to find it again, issuing copies to those entitled to them. A sale signed today will be read again during an estate settlement forty years from now, by people who had not been born when it was signed.
That requirement of duration shapes how an office is organised: filing, registers, security of the premises, transfer of the archive when an office changes hands or closes.
It also shapes the drafting itself. A deed has to stay understandable for a reader who was not in the room and who will have nobody left to ask: the parties, the subject matter, the conditions and the cross-references must be identifiable without outside context. A text that was clear on the day of signature and obscure thirty years later has not done its job. The precise rules on safekeeping and on issuing copies are set by national law and by the competent professional organisation.
Making a deed travel: the apostille
A deed perfectly valid at home may be refused abroad, because the receiving authority cannot verify where it came from.
The Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents, drawn up by the Hague Conference on Private International Law, addresses that problem. It has 130 Contracting Parties, which makes it one of the most widely applied multilateral treaties in the field of legal cooperation.
The mechanism is simple, and often misunderstood. The Apostille issued by a Competent Authority authenticates the origin of the public document: the signature, the capacity of the signatory, and the identity of the seal or stamp. It does not certify the content of the deed. Between Contracting Parties, it replaces the chain of legalisations. An electronic Apostille programme has existed since 2006, and an Apostille cannot be refused on the sole ground that it was issued in electronic form.
Digital tools enter the office
Dematerialisation now touches drafting, signature and safekeeping alike.
The UNCITRAL Model Law on Electronic Signatures, adopted on 5 July 2001, offers States a framework built on two ideas: functional equivalence, which lets an electronic signature satisfy a legal signature requirement where it offers the required guarantees, and technological neutrality, which avoids locking the law into one given technique. The text also provides that foreign certificates and signatures be recognised on the basis of substantive equivalence, regardless of where they were issued.
A model law is not a treaty: it applies only where a State has enacted it, possibly with adaptations. Whether a deed can be signed electronically, and in what form, therefore depends on the law of the country concerned and on the rules of the local notariat.
A profession that does not exist the same way everywhere
This is the most important caution in this article. The word "notary" does not cover the same reality across legal systems.
In countries with a notariat of the Latin tradition, the notary is the public official described above, with a duty to advise, a legality check and the production of authentic deeds. In other systems, the person called a notary public performs far more limited functions, often centred on certifying signatures, without comparable drafting or substantive checks.
Entry into the profession itself varies: the International Union of Notaries recalls that the conditions are set by each State's law, while requiring that candidates always hold a law degree and the highest legal qualification, and that notaries be members of a collegiate body representing the whole profession in the country.
What a notary does not guarantee
A notary does not guarantee that a transaction will be profitable, that a property will gain value, or that no future dispute will arise. Their intervention alone does not issue title to property: the issuing and publicity of rights fall, depending on the country, to separate administrations and registers with their own procedures.
Nor can they promise that a deed received in their office will be accepted anywhere abroad: that depends on the receiving country, on the applicable conventions, and sometimes on translation requirements or additional formalities.
What they do commit to is the check they carried out, the clarity of what they explained, the conformity of what they drafted and the safekeeping of what they received. That is already a great deal, and it is verifiable.
As with any legal question, a discovery article does not replace a consultation. The rules vary from country to country, and a real situation is handled with a qualified professional in the country concerned.
