Apostille Process for International Filings: How the Route Works
The apostille process is the route by which a public official certifies that a signature, seal or stamp on a document is genuine, so a foreign authority can accept it without further proof. In the UK, the competent authority for this is the Foreign, Commonwealth & Development Office (FCDO), which issues apostilles under the Hague Apostille Convention. Gregory Mappledoram Notary Public handles this daily for in-house legal teams and solicitors who need documents to work abroad.
The practical sequence rarely changes:
- A notary certifies the document
- The FCDO attaches the apostille
- The document goes to the destination country
Most delays come before step one, not step two.
Who issues the apostille in the UK
The FCDO’s Legalisation Office is the only body that can issue an apostille in the UK. A notary cannot issue one, and neither can a solicitor.
We prepare the document so it is ready for that office. That means a properly worded notarial certificate, a clear signature block with the relevant notary details, and the notary’s own seal of office. If any of these are wrong, the FCDO will not issue the apostille, so the notary ensures that any notarial act is complete and contains the correct information before submitting to the FCDO.
When consular legalisation is still required
Some countries are not party to the Hague Apostille Convention (HCCH | #12). For those, an apostille is not enough, and the document must also go through consular legalisation.
This usually means a two-stage route: the FCDO confirms the notary’s signature and seal, then the destination country’s embassy or consulate legalises the FCDO’s stamp. A few countries also require their own embassy to see the document before the FCDO stage.
Check the destination country’s requirements before you start. Getting this order wrong means paying for a second round of fees and losing days.
Apostille Versus Legalisation: Which Route Your Filing Needs
An apostille is a single certificate for countries in the Hague Apostille Convention. Legalisation is the longer consular route for countries outside it. The destination country decides which one applies, not the sender.

If your filing is going to a Hague Convention country, the apostille route is faster and simpler. If not, budget extra time for the consular stage, because embassy opening hours and appointment systems add delays you cannot control.
The Hague Conference on Private International Law status table lists which countries are party to the Convention. Check it before you commit to a route.
Documents Required for an Apostille: What to Prepare Before You File
The documents required for an apostille depend on what the destination authority has asked for. At a minimum, you need the original document, a notarial certificate, and proof of the notary’s standing.
Prepare these before you file:
- The original document, not a photocopy, unless the destination accepts certified copies
- A signed notarial certificate attached to or endorsed on the document
- Photo identification for the signatory
- Company authority documents if a company officer is signing
- A covering note stating the destination country and the purpose
Photocopies are the most common cause of rejection. Many destination authorities will only accept an apostille on the original, or on a copy that a notary has certified in a specific way.
Apostille Checklist for Corporate Filings
Corporate filings need more preparation than personal ones. Board resolutions, registers and powers of attorney all carry their own signing rules, and a foreign registry will check them.
Board resolutions, registers and powers of attorney
A board resolution must be signed by the correct officers, and the notary must be able to confirm their authority to sign. That usually means seeing the company’s constitutional documents and a current register of directors.
Company registers must be certified as true copies by someone with the authority to do so. A power of attorney needs a clear scope, a named attorney, and a signature witnessed in the right form.
Use this checklist before you send anything:
- Confirm the destination country and its route (apostille or legalisation)
- Check the signatory’s authority against the register of directors
- Attach the notarial certificate in the form the destination expects
- Confirm whether the original or a certified copy is required
- Check the destination’s language requirements, and whether a translation is needed
- Keep a scanned copy of everything before it leaves your office
Apostille Processing Time: What Drives the Clock
Apostille processing time is driven by three things: how quickly the notarisation is done, how long the FCDO takes, and how long the consular stage takes if one applies.
The FCDO publishes its current turnaround options on its own service pages, so check there for the latest position rather than relying on second-hand estimates. FCDO legalisation service guidance sets out the standard and premium options and how to submit documents. Given the FCDO is now based in Milton Keynes we use the services of a legalisation agent to obtain the apostille for us from the FCDO.
For time-pressured transactions, the practical lever is the first stage. If the notarisation is clean and complete, the document can move straight into the FCDO queue. If it is not, it comes back, and the clock restarts.
Common Mistakes That Get Filings Rejected Abroad
Delays and rejections usually come from small formatting errors, not from the apostille itself. The certificate is valid but the document underneath it is not.
The mistakes we see most often:
- Signing in the wrong capacity, so the notary cannot confirm authority
- Using a photocopy when the destination wants the original
- Missing a translation, or using a translator the destination does not accept
- Sending the document to the wrong route, apostille instead of legalisation
- Failing to check whether the destination needs the apostille on the translation as well
Each of these costs a full cycle. A rejection abroad can also mean the receiving authority sets a new deadline, which is the real cost.
Cross-border filings rarely fail because of the apostille itself. They fail because the document underneath it was not prepared for the destination jurisdiction, and by the time that surfaces, the deadline is close. Gregory prepares documents to work in the destination country, with same-day service for time-pressured transactions, and support built for in-house legal teams and referring solicitors.

Frequently Asked Questions
Does a document need notarising before it can be apostilled?
Most documents must be notarised before the FCDO will attach an apostille. The notary confirms the signatory’s identity, authority and signature, then the document goes to the FCDO for the apostille itself. Corporate documents such as board resolutions, powers of attorney and certified copies of registers almost always follow this route. Skipping notarisation is a common reason for rejection, so confirm the sequence before you send anything.
How long does the apostille process take?
Apostille processing time depends on the FCDO’s current turnaround, the volume of documents and whether you use a premium or standard service. Notarisation and any consular legalisation add further days. For a cross-border closing, build in buffer time and confirm the destination authority’s requirements before the deadline. A notary experienced in international filings can often compress the front end of the process when timing is tight.
How can I check whether the destination country accepts an apostille?
Check whether the destination country is a party to the Hague Apostille Convention. If it is, an apostille issued in the UK should be accepted without further legalisation. If it is not, consular legalisation is usually required instead. Always verify with the receiving authority or the destination embassy, because some countries accept apostilles for certain documents but not others. Getting this wrong is one of the most common causes of rejected filings.
What should I do if a document is rejected by the receiving authority?
Ask the receiving authority to state the exact reason in writing. Common causes include a missing notarial certificate, an expired document, a translation issue or a formatting problem. Once you know the reason, the document can usually be re-notarised and re-submitted. Keep a record of the rejection so the same fault is not repeated on the next filing. A notary familiar with the destination jurisdiction can often spot the problem before the document leaves the UK.
