You've formed a Delaware LLC. Now you need to open a business bank account in Portugal, apply for residency using your company, or sign a commercial contract with a foreign counterpart. Someone tells you that you'll need an apostille. You look it up. Within ten minutes, you've encountered three different processes — apostille, authentication, legalization — and you're less sure than when you started.

This guide clears that up. It explains what an apostille actually is, when it applies, and when it's not enough. It covers the Delaware and Wyoming processes with specific fees and timelines. And it explains in detail what happens when the destination country isn't part of the Hague Convention — because that changes everything, and most guides don't tell you until you're already mid-process.

What is an apostille?

An apostille is a standardized certificate that authenticates the origin of a public document — confirming that the signature or seal on the document is genuine and was issued by a recognized authority. It does not certify the content of the document itself. It certifies that the document is what it claims to be.

Apostilles exist because of the 1961 Hague Convention Abolishing the Requirement of Legalisation for Foreign Public Documents. Before this convention, getting a document accepted in a foreign country required a lengthy chain of authentication through diplomatic channels. The convention replaced that chain with a single certificate — the apostille — for member countries.

As of 2026, 128 countries are members of the Hague Apostille Convention, including the United States, the United Kingdom, all EU member states, and most of Latin America. Notable recent joiners: Canada (January 2024), China (November 2023), and Bangladesh (March 2025). The official and current member list is maintained at hcch.net.

When an apostille is sufficient — and when it isn't

If you are sending documents to a country that is a Hague Convention member, an apostille is the correct and sufficient form of authentication. The receiving authority in that country is obligated to accept it.

If you are sending documents to a country that is not a Hague Convention member — and this is the part most guides bury — an apostille does nothing. The receiving country has no obligation to recognize it. You need a full multi-step legalization chain instead. Three countries that frequently appear in the Atlasway audience's plans and are not Hague members: UAE, Saudi Arabia, and Qatar.

Apostille vs. full legalization chain

An apostille is a single certificate issued by a designated authority in the country where the document originated. For US company documents, that authority is typically the Secretary of State of the issuing state — or, for federal-level documents, the US Department of State.

A full legalization chain is something different: a sequential process where each step must be completed before the next can begin. For a US company document going to a non-Hague country, the chain typically looks like this:

  1. Notarization by a licensed US notary public (original, wet-ink signature required — electronic notarization is not accepted)
  2. Authentication by the Secretary of State of the issuing state
  3. Authentication by the US Department of State (Washington, DC)
  4. Legalization by the foreign country's embassy or consulate in the US
  5. In some countries (UAE, for example): additional attestation by the Ministry of Foreign Affairs (MOFA) once the document arrives in-country

Each of these steps is a separate submission with its own fee and wait time. They cannot be done in parallel. If any step is rejected, you go back to the beginning of that step — not the beginning of the chain.

The US Department of State bottleneck

In any non-Hague legalization chain, the US Department of State's Office of Authentications is almost always the longest step. The current processing times as of late 2025:

  • Walk-in service (hand delivery to Washington, DC): 7–10 business days. The office is open Monday through Thursday only.
  • Mail-in submissions: 3–5 weeks.
  • Same-day emergency service: available only for narrow qualifying circumstances (life-or-death situations, court orders with imminent deadlines).

That single step adds weeks to the process before you ever reach the foreign embassy. Budget accordingly.

For UAE, Saudi Arabia, and Qatar specifically

These three countries are not Hague Convention members, and this surprises founders who assume that two heavily globalized economies — UAE and Saudi Arabia — would have joined by now. They haven't.

For documents going to the UAE, the local term is "attestation" rather than apostille. The process for a US LLC document going to the UAE runs through all five steps listed above: notarization, Delaware (or other state) Secretary of State, US Department of State, UAE Embassy via VFS Global (the UAE Embassy does not accept walk-in requests), and MOFA stamping inside the UAE after the document arrives.

Important: If you are using company documents for a Dubai freezone application or UAE residency, start the legalization process before you submit your visa application — not after. The full chain takes 6–10 weeks DIY, or 3–4 weeks with an experienced third-party service. If you're exploring the Dubai freezone formation process, factor this timeline into your planning from the start.

The same principle applies to Saudi Arabia and Qatar — non-Hague members requiring full chain legalization through their respective embassies.

When you need an apostille for company documents

Opening a foreign bank account

Most non-US banks require authenticated company documents before they will open a business account. Exactly which documents vary by bank and jurisdiction, but a typical requirement looks like this:

  • Apostilled Certificate of Incorporation or Certificate of Formation
  • Apostilled Certificate of Good Standing (often required to be recent — typically less than 90 days old)
  • Sometimes: apostilled Operating Agreement or Articles of Organization

European banks and Singapore banks are increasingly the target for non-resident founders. Some accept certified copies; others require the full apostille chain. Ask the bank in writing before you start any authentication process — their requirements should be confirmed before you spend time and money on the wrong set of documents.

Residency and visa applications

Some residency programs require proof that a company was legitimately formed in your home jurisdiction. Portugal's D8 Digital Nomad Visa, for example, may require documented proof of a foreign company and its income. The immigration authority receiving your application — not you — determines whether an apostille is sufficient or whether something else is required.

If you're pursuing residency through company ownership, verify the document requirements with the receiving authority or a local immigration advisor before beginning the authentication process.

Contracts and commercial agreements

When signing major contracts with foreign governments or large commercial counterparties, your company formation documents may need to be authenticated. Power of attorney documents executed in the US for use abroad also frequently require apostille — especially when a foreign signatory is acting on behalf of your company.

How to get an apostille for Delaware LLC documents

Delaware is the most common US state for non-resident LLC formation, so this process is worth covering in full. For background on why Delaware is common for this purpose, see Atlasway's guide on forming a Delaware LLC as a non-resident.

Which Delaware company documents can be apostilled

The Delaware Division of Corporations apostilles the following:

  • Certificate of Formation (for LLCs)
  • Certificate of Incorporation (for corporations)
  • Certificate of Good Standing
  • Certified copies of filed documents
  • Any document bearing a Delaware notary public's signature or the signature of a Delaware public official

Important limitations:

  • Each document requires its own apostille — no bundling multiple documents under one cover certificate.
  • Delaware does not apostille documents that were notarized electronically.
  • Delaware cannot apostille out-of-state documents or photocopies.
  • Federal documents must go through the US Department of State, not the Delaware Secretary of State.

If you need both an original and a copy, request a certified copy from the Division of Corporations first — that certified copy can then be apostilled.

Step-by-step: Delaware Secretary of State apostille process

  1. Obtain the original document or a certified copy from the Delaware Division of Corporations (if you don't already have it).
  2. Confirm the document bears either a Delaware notary signature or the signature of a Delaware public official.
  3. If the document is in a foreign language or needs translation, obtain a certified English translation — both the original and translation must be notarized.
  4. Prepare a cover letter stating: the purpose of the request, the destination country, and the number of documents.
  5. Submit to: Division of Corporations, John G. Townsend Building, 401 Federal Street, Suite 4, Dover, DE 19901.
  6. Pay the $30 state fee per document (standard) or $70 per document (24-hour expedited).
  7. Include a prepaid return envelope or shipping label if submitting by mail.

For in-person submission, appointments are required. Call 302-739-3077 to schedule. General inquiries: 302-739-3073. Full submission guidelines are on the Delaware Division of Corporations website.

Timelines and fees — Delaware

Service levelState feeProcessing time
Mail (standard)$30/documentSame business day received + mail transit
In-person (by appointment)$30/documentSame day
24-hour expedited$70/document ($30 + $40 surcharge)24 hours after receipt
Same-day counter service$80/document ($30 + $50 surcharge)Same day, at counter

Mail transit in each direction adds 1–3 business days each way. For time-sensitive submissions, in-person is more reliable.

Wyoming LLC apostille process

Wyoming is the second-most-common privacy-forward US state for non-resident LLC formation. The apostille process differs from Delaware in a few meaningful ways.

For a comparison of how the two states stack up overall, see Atlasway's guide on Delaware vs. Wyoming LLC.

Step-by-step: Wyoming Secretary of State apostille process

Wyoming does not offer walk-in service. All submissions are by mail to the Wyoming Secretary of State in Cheyenne.

  1. Obtain a certified copy of the relevant document from the Wyoming Secretary of State's Business Division (cost: $10 for up to 10 pages).
  2. Complete the Wyoming apostille request form (available at sos.wyo.gov).
  3. Submit by mail with: the document, the request form, a $20 fee per document, and a prepaid return envelope.
  4. Standard processing: 5–7 business days after receipt. If the Business Division needs to retrieve the document, it can extend to 15 business days.
  5. No expedited service is available for Wyoming apostilles.

Wyoming's lower fee ($20 vs. Delaware's $30) is partially offset by the inability to expedite. If timing is tight, plan around a two-week total turnaround including shipping.

Apostille services vs. doing it yourself

When DIY makes sense:

  • You are physically in the US and can travel to the Secretary of State's office in person.
  • You need only one or two documents.
  • The destination country is a Hague Convention member.
  • You have time — two to four weeks of buffer.

When a third-party service is worth the cost:

  • You are based outside the US and cannot appear in person.
  • You have multiple documents to authenticate.
  • The destination is a non-Hague country requiring a full legalization chain.
  • The timeline is tight and you need to guarantee turnaround.

Third-party services for Hague-destination apostilles typically cost $100–$300 per document, all-in, including state fees and handling. For a full non-Hague legalization chain — notarization, state authentication, USDOS, and foreign embassy — expect $300–$600 per document when using a professional service.

Common mistakes that cause rejections:

  • Submitting a photocopy for apostille instead of an original or certified copy. Banks frequently reject apostilles placed on photocopies — they want the apostille attached to the original document or an officially certified copy.
  • Using electronically notarized documents where wet-ink signatures are required (particularly relevant for non-Hague destinations and many foreign banks).
  • Forgetting to include a cover memo specifying the destination country. Delaware requires this.
  • Assuming one apostille covers multiple documents. Each document needs its own.

e-Apostille: what's changing in 2025–2026

Several US states now issue digital (electronic) apostilles — certificates that carry the same legal validity as paper ones but are transmitted electronically and verified via a digital portal. As of early 2026, states with active e-apostille programs include Kentucky, Minnesota, Washington, Connecticut, Montana, Rhode Island, and Utah.

Delaware issues paper apostilles only, but maintains an electronic verification portal that allows receiving authorities to verify the authenticity of a Delaware apostille online.

The practical limitation: not all destination countries or foreign institutions accept e-apostilles. The legal framework supports them, but acceptance in practice depends on the receiving authority. European counterparties in countries like Portugal, Spain, and France are increasingly comfortable with them. Foreign banks are more cautious — many still require paper.

If a European bank or counterparty accepts e-apostilles, the turnaround time is substantially faster. If you're dealing with a foreign bank that insists on physical documents, e-apostilles don't yet provide a meaningful shortcut.

Who this is not for

You don't need an apostille if:

  • Your company documents are only being used domestically. Apostilles are exclusively for international use.
  • The foreign institution accepts a notarized copy without further authentication. Some banks and counterparties — particularly in jurisdictions with close US ties — accept certified copies with no further authentication. Confirm before assuming.
  • The document in question is a federal document and you're dealing with a Hague Convention country. Federal documents (IRS letters, federal corporate filings) need authentication from the US Department of State, not a state Secretary of State. The process overlaps but is not identical.

This guide is not the right starting point if:

  • You are dealing with personal documents (birth certificates, marriage certificates, educational diplomas). The apostille process works similarly, but the specific requirements and issuing authorities differ.
  • Your company was formed in a state other than Delaware or Wyoming. The general process described here applies, but specific fees, processing times, and submission addresses vary by state. Always check your state's Secretary of State website directly.
  • Your documents need to be used in a country where the specific bank or authority has requirements beyond standard apostille. Some institutions add requirements that go beyond legal sufficiency. Verify with the receiving institution before starting.

The destination country determines everything

The master rule for apostilles is simple: the destination country determines the process, and that determination happens before anything else.

If the destination is a Hague Convention member — most of Europe, the UK, much of Latin America, Canada, China — you need an apostille from the Secretary of State of the state that issued your documents. For a Delaware LLC, that is a $30 state fee, same-day or 1–2 days processing, and a realistic total turnaround of one to two weeks including shipping.

If the destination is not a Hague Convention member — UAE, Saudi Arabia, Qatar being the most relevant to the Atlasway audience — you need a full legalization chain running through the US Department of State and the foreign country's embassy. Budget 6–10 weeks for the DIY version. If you use an experienced third-party service with expedited handling, 3–4 weeks is realistic.

Start early. The USDOS is the bottleneck in every non-Hague chain, and its mail-in processing alone takes 3–5 weeks. There is no shortcut that bypasses it.

For the official current list of Hague Convention member countries, see hcch.net. For the US Department of State apostille requirements and Office of Authentications, see travel.state.gov.

If you are forming a company specifically for international use — or if you're at the stage of choosing a jurisdiction — it is worth thinking through where your documents will need to go before you commit to a state. For the Belize IBC formation path specifically, authentication requirements can differ because Belize operates under a different legal tradition. Knowing the end-use before you start formation saves significant time later.
