Apostille in New England: When You Need One and Where to Get It

One of the most common — and most expensive — mistakes in Hungarian document processing is confusing an apostille with a consular authentication. They look similar, they both involve official stamps, and Hungarian authorities sometimes request both on the same document. Understanding the difference before you start your paperwork can save you weeks of rework and, in some cases, a missed legal deadline.

This guide explains what an apostille is, what consular authentication is, when you need each one, and — practically — where to get an apostille if you live in New England.

What Is an Apostille?

An apostille is a standardized authentication certificate created by the 1961 Hague Convention on Abolishing the Requirement for Legalisation of Foreign Public Documents. When a document is issued by a government authority in one country and must be used in another country that is also a signatory to the Hague Convention, an apostille certifies that the issuing authority is legitimate and that the official who signed the document held the authority to do so.

In New Hampshire, apostilles are issued by the New Hampshire Secretary of State. The process applies to any document issued by a New Hampshire government authority — birth certificates from the NH Bureau of Vital Records, court orders, notarized documents, and similar public documents. The apostille does not verify the contents of the document; it certifies the authenticity of the official signature and seal.

What Is Consular Authentication?

Consular authentication — also called consular legalization — is performed by a consular official and certifies that a document is genuine and suitable for use in a specific country. When this office authenticates a US document for use in Hungary, we are certifying the document's origin and legitimacy from a diplomatic standpoint. This carries the authority of the Hungarian government and is recognized by Hungarian courts, notaries, registries, and institutions.

Consular authentication is what the Honorary Consulate of Hungary — New England performs. It is distinct from an apostille, and in many cases, Hungarian authorities require one, the other, or both — depending on the nature of the document and how it will be used.

Apostille vs. Consular Authentication: When You Need Each One

Apostille only

If Hungary is accepting a standard US public document and does not require further consular involvement, an apostille from your state Secretary of State is typically sufficient. This applies most commonly to US birth certificates submitted for Hungarian civil registry purposes, and US marriage certificates submitted in connection with Hungarian administrative proceedings. Hungary is a Hague Convention signatory, so US documents with a valid apostille are generally recognized as authentic without additional consular certification.

Consular authentication only

When a document is being submitted to a Hungarian authority that specifically requires consular certification — for example, a power of attorney witnessed at the consulate, or a signed declaration certified by a Hungarian consular official — the apostille is not the relevant step. The consular seal and signature from this office provides the authentication the Hungarian authority needs.

Both apostille and consular authentication

Some Hungarian proceedings require both. A common example is a US birth certificate submitted for citizenship by descent: the document typically needs an apostille first (certifying it as a genuine US public document), followed by consular review and, in some cases, an additional certification by this office that the document meets the requirements of the specific application. Your Hungarian attorney or the Hungarian authority requesting the document should specify what chain of certifications they require.

Which Countries Accept Apostille — and Which Require Full Legalization

The Hague Apostille Convention has 124 signatory countries as of 2026. For documents used in those countries, an apostille replaces the longer chain of authentication previously required. Hungary is a signatory. Most EU member states are signatories. Most of the countries where New England residents commonly need to submit documents — Hungary, Germany, France, Italy, Portugal — are covered.

For non-Hague countries, the process is different: a full "chain" legalization is required, which involves the US Secretary of State, the US State Department, and then the receiving country's embassy or consulate in the US. If you are submitting a document to a country that is not on the Hague Convention list — certain Middle Eastern, African, or Asian countries — you will need a different process entirely. Contact this office or the receiving country's consulate in the US to confirm the correct procedure.

Practical Examples

Selling property in Hungary

If you are selling Hungarian real estate and need to sign documents from New England, you will typically execute a power of attorney at this consulate (consular authentication). Your Hungarian attorney will specify whether additional apostille certification on supporting documents is also required.

Document for use in the EU

For most EU member states, a US public document with an apostille from the appropriate state Secretary of State is sufficient. Consular authentication is an additional step that may or may not be required depending on the specific institution and country.

Document for a non-Hague country

For countries outside the Hague Convention, neither an apostille nor a consular authentication from this office will be sufficient. The chain legalization process must go through the US State Department and the receiving country's US embassy. If your matter involves a non-Hague country, contact us and we will point you in the right direction.

Where to Get an Apostille in New England

• New Hampshire: NH Secretary of State, Apostille and Authentication Division — Concord, NH. Processing times vary; expedited service available.
• Massachusetts: Secretary of the Commonwealth, Apostille and Authentication Services — Boston, MA. Online and in-person requests accepted.
• Vermont: Vermont Secretary of State, Authentications Office — Montpelier, VT.
• Rhode Island: Rhode Island Secretary of State — Providence, RI. Requests submitted by mail.
• Maine: Maine Secretary of State, Division of Corporations, Elections and Commissions — Augusta, ME.
• Connecticut: Connecticut Secretary of State — Hartford, CT. In-person and mail submissions accepted.

Each state's Secretary of State handles apostilles only for documents issued in that state. If your document was issued in a different state than where you currently live, you must obtain the apostille from the Secretary of State of the state where the document was issued — not your current state of residence.

The most important rule: apostille from where the document was issued, not where you live. A New Hampshire apostille cannot certify a Massachusetts birth certificate.

Not Sure Which Route Applies to Your Situation?

The correct path depends on the document type, the receiving Hungarian institution, and what they have specifically requested. If you have a letter or form from a Hungarian authority describing what they need, bring it to your appointment or send it to us via the contact form — we will review it and tell you exactly which steps are required, in what order, before you take any action.
