How we handle clinical investigator documents
Investigator documents for a foreign trial site come from several issuers, follow different authentication rules and often need to reach more than one site. We plan the packet against the CRO’s document list, so every original arrives at the right site in a form its ethics committee and regulator will accept.
- 1
We map the packet first
Send us the site’s document list and the countries involved. We confirm which items are notarized signatures, which are certified copies and which must come from an issuing authority, and we flag anything the Secretary of the Commonwealth will not authenticate in its current form.
- 2
We obtain what only the issuer can provide
A medical license is authenticated through a signed verification from the Board of Registration in Medicine, not a copy of the license. We request it in the form the Secretary of the Commonwealth recognizes and follow it through.
- 3
We meet the investigator
We come to the investigator’s hospital, clinic or office across Greater Boston, between clinical commitments. Certified copies and signed declarations are completed in the same visit, with a set prepared for each site.
- 4
Apostille or legalization
We file in person with the Massachusetts Secretary of the Commonwealth, typically within 1–2 business days of having every item in hand. For countries outside the Hague Convention, we continue through the U.S. Department of State and the embassy.

Delivered to each site
Scans of the completed documents are emailed to you before they ship. Each site’s set ships separately with tracking, accompanied by an index matching every apostille number to its document.
What clinical investigator document apostilles are, and when sites ask for them
When a U.S.-based physician serves as principal investigator or sub-investigator for a study conducted abroad, the foreign site, its ethics committee or the national regulator often asks for proof of the investigator’s identity, training and authority to practice. Because those records are American, the foreign authority asks for them to be authenticated with an apostille, or legalized through the embassy when the country is not part of the Hague Convention.
These requests usually arrive during study start-up, through the CRO or site management organization coordinating the country submission. The list varies by country and by site, but it commonly includes the medical license or a license verification, a copy of the passport, the medical diploma, specialty and fellowship certificates, and sometimes a signed CV or investigator declaration.
This page is written for the teams who assemble those packets: CROs, sponsors’ clinical operations groups, site start-up specialists and the investigators themselves. If you are a physician authenticating your own credentials to practice abroad rather than to join a study, see our page on physician license and credential apostilles. For sponsor-level documents such as powers of attorney and FDA certificates, see clinical research and CRO apostilles.
From our recent work
Each example below is drawn from a real engagement for a clinical program. Investigator, sponsor and site details are kept confidential.
One investigator, two countries, three sites
A Boston hospital physician was named principal investigator for a study with sites in Panama and El Salvador. The Latin American CRO’s list called for a license verification, a passport copy, the medical diploma and a fellowship certificate. We prepared a complete apostilled set for each country, and every document was apostilled within two days of the last item reaching us.
A license that could not be apostilled as issued
The investigator’s license certificate carried signatures the Secretary of the Commonwealth did not have on file, and that office confirmed a copy of a state-issued license cannot be certified by a notary. We obtained a signed verification from the Board of Registration in Medicine instead, which the Secretary of the Commonwealth then apostilled.
A site added after the packet was finished
After the first sets were complete, the CRO asked for originals at a second Panama site. We issued an additional apostilled set for that site rather than splitting the existing packet, and shipped all three sets directly to their sites.
An index for each site team
Each shipment went out with a list pairing every apostille number with the document it authenticates, so the site coordinators could match the originals against their submission. The CRO confirmed that all three sites received their documents.
Sponsor documents for a Costa Rica site
For a medical technology company opening a site in Costa Rica, we notarized and apostilled the clinical trial agreement in English and Spanish, the sponsor commitment form and the legal representative letter, signed by the company’s chief executive at a location of her choosing.
A signature page caught before shipping
While preparing the Costa Rica set for apostille, we found an additional signature page embedded in the middle of the agreement, in both language versions, that had not been signed. We returned before the signer’s scheduled travel so the agreement was fully executed before it left for Costa Rica.

Which investigator documents follow which route
The route depends on what the document is and who issued it. These are the items CROs most often request for a U.S. investigator joining a site abroad.
| Document | How it is prepared | Authentication |
|---|---|---|
| Medical license | A signed verification from the Massachusetts Board of Registration in Medicine, requested in a form the Secretary of the Commonwealth recognizes | Massachusetts apostille, or legalization for non-Hague countries |
| Passport | Certified copy made by a notary from the original, presented in person | Massachusetts apostille on the notarial certificate |
| Medical diploma | Certified copy, or a copy certified through the school when the destination requires it | Apostille from the state where the certificate was completed |
| Specialty, residency and fellowship certificates | Certified copy, or a letter from the training institution when requested | Apostille or legalization |
| Signed CV or investigator declaration | Signed by the investigator before the notary, with an acknowledgment or jurat as the site specifies | Apostille or legalization |
| GCP or protocol training certificates | Certified copy, when the site asks for an authenticated version | Apostille or legalization |
An online license lookup or a printout from a verification website cannot receive an apostille, because there is no official signature to authenticate. For physicians licensed in another state, the verification comes from that state’s board and the apostille from that state’s Secretary of State. See apostilles from any U.S. state.
Why the license itself is often the hardest item
An apostille certifies the signature and capacity of the official who signed a document. The Secretary of the Commonwealth can only issue one when it has that official’s signature on file. A license certificate signed years ago by board members whose signatures are not on file cannot be apostilled, however genuine it is.
A notarized copy of the license is not a substitute. In our experience the Secretary of the Commonwealth will not accept a notary’s certified copy of a state-issued document, because the state document must be authenticated through its issuing office. The practical answer is a license verification signed by a Board official whose signature the Secretary of the Commonwealth recognizes. When that office asked us for proof of an official’s authority, it required a letter on the Board’s letterhead, signed, naming the office and stating that the signer is authorized to issue such documents.
Because the verification is the item with the longest lead time, we request it first and prepare the certified copies while it is in progress. When more than one country or site needs an original, we request enough verifications at the outset, so a later site does not wait on a second request.
Certified copies of the passport, diploma and certificates
Most foreign sites do not expect an investigator to surrender an original diploma or passport. Instead, a Massachusetts notary makes a copy from the original, compares the two and completes a copy certification, which states that the copy is true, exact, complete and unaltered. The Secretary of the Commonwealth then apostilles the notary’s certificate.
The original must be presented to the notary in person; a scan or photograph cannot be certified as a copy. We make one certified copy for each set, so every site receives its own apostilled original. For background on what a Massachusetts notary can and cannot certify, see can a notary certify a copy in Massachusetts.
Some destinations prefer a diploma copy certified by the school, or an apostille on a registrar-certified copy, rather than a notarial copy certification. When the CRO’s list specifies a route, we follow it; when it does not, we confirm the preferred form with the coordinating team before the investigator’s appointment.
Mistakes that delay an investigator packet
- Submitting the license certificate itself. If the signatures are not on file with the Secretary of the Commonwealth, the license cannot be apostilled. Start with a Board verification.
- Relying on an online lookup. A printout from a verification website has no official signature, so it cannot be authenticated.
- One packet for several sites. Each site that requires originals needs its own complete, separately apostilled set. Splitting one set leaves every site incomplete.
- Copies made from scans. A certified copy must be made from the original document, presented in person.
- Signing the CV or declaration in advance. A jurat requires the investigator to sign in the notary’s presence after taking an oath or affirmation.
- Missing pages in long agreements. Signature pages embedded mid-document are easy to overlook. We review every page before filing.
- Assuming every country accepts an apostille. Sites in non-Hague countries require state authentication, the U.S. Department of State and the embassy, which takes considerably longer.
- Shipping without an index. When a set contains several apostilles, a list matching apostille numbers to documents saves the site team time and prevents questions.

Timing against a study start-up schedule
Once every item is in hand, Massachusetts apostilles are typically issued within 1–2 business days because we file in person. In the engagement above, all eight apostilles for two countries were issued within two days of the Board verification arriving. When a deadline has required it, we have obtained apostilles the same day.
The variable is usually the Board verification, which depends on the Board’s processing, and the legalization route for non-Hague countries, which usually takes 4–6 weeks because it passes through federal and embassy processing. We build the plan around those two factors and keep the coordinating team informed at each stage.
International shipping is arranged by tracked courier directly to each site. We do not promise delivery dates on behalf of the carrier, but we share tracking for every package and confirm receipt with your team.
Translation for the site and regulator
Many Latin American and European sites require a certified translation of each authenticated document, and sometimes of the apostille itself. When the destination requires it, the translation is prepared after authentication, so that the apostille is translated along with the document.
As a corporate member of the American Translators Association, we provide certified translation in 65+ languages, including Spanish and Portuguese, coordinated in the same order as the apostilles.
What to send us before the appointment
- The site’s or CRO’s document list, by country and site
- The investigator’s name exactly as it appears on the passport, and the state or states where they are licensed
- How many sites need originals, and the shipping contact and address for each
- Any forms the site requires the investigator to sign, unsigned
- Your site activation or submission date
We are notaries and document specialists, not attorneys or regulatory consultants. The CRO and the site decide which documents the submission requires; we make sure each one is executed, certified and authenticated so the site can rely on it.

Frequently asked questions
Can a medical license be apostilled for a clinical trial abroad?
Usually not in its original form, because the Secretary of the Commonwealth must have the signing officials’ signatures on file. The reliable route is a license verification signed by a Board of Registration in Medicine official whose signature that office recognizes, which is then apostilled.
Can a notary certify a copy of a medical license for an apostille?
In our experience, no. The Secretary of the Commonwealth has told us that a notary cannot certify a copy of an official state document for this purpose. The license is authenticated through a verification from the issuing board instead.
Can you certify copies of the investigator’s passport and diploma?
Yes. The investigator presents the originals in person, and a Massachusetts notary makes and certifies a copy of each. The Secretary of the Commonwealth then apostilles the notarial certificate.
How many sets do we need if the study has several sites?
One complete set for each site that requires originals. We prepare and apostille each set separately and can add a set later if another site joins.
How long do investigator document apostilles take?
Once every item is in hand, Massachusetts apostilles typically take 1–2 business days. The Board verification and any embassy legalization for non-Hague countries are usually what set the overall timeline.
Can you ship the documents directly to the foreign sites?
Yes. Each site’s set ships by tracked international courier to the site contact, and we email scans of the completed documents before anything ships.
What if the investigator is licensed in another state?
The license verification comes from that state’s medical board and is apostilled by that state’s Secretary of State. We coordinate the request and the authentication, while the certified copies can still be completed in Massachusetts.
Do the documents need to be translated?
Many sites require a certified translation, often into Spanish or Portuguese. We confirm the requirement with the coordinating team and provide the translation after authentication, so the apostille is translated as well.
Can the investigator sign at the hospital?
Yes. We meet investigators at their hospital, clinic or office across Greater Boston, scheduled around clinical commitments.
