Can a Medical Letter Be Apostilled in the UK?

Yes, a medical letter can usually be apostilled in the UK, provided it meets the requirements set by the FCDO (Foreign, Commonwealth & Development Office). GOV.UK lists a medical certificate signed by a registered doctor as an eligible document type for apostille legalisation, and most properly formatted medical letters fall into this category.

However, not every medical letter will be accepted. The FCDO needs to verify the signatory, and the document must contain specific professional details. Letters that are unsigned, lack clear doctor information, or carry only a digital signature are commonly rejected.

As a registered FCDO apostille service, we pre-check every document before submission to avoid unnecessary delays. This guide walks you through exactly what makes a medical letter eligible, what mistakes to avoid, and how to get your document apostilled quickly.

Before submitting your medical letter for an apostille, make sure it meets all of the following criteria. The FCDO will check these details during the verification process, and missing any one of them could result in rejection.

• Issued in the UK by a UK-based medical practice or hospital
• Signed by a GMC-registered doctor with a wet ink signature (for paper apostille)
• Doctor’s full name printed clearly on the letter
• GMC registration number included on the document
• Practice address stated on the letterhead or within the body of the letter
• Date of issue clearly shown
• Clear clinical statement relevant to the letter’s purpose (e.g. fitness to work, general health confirmation)

If your letter ticks all of these boxes, it can typically go directly to the FCDO for an apostille without notarisation or solicitor certification. If you are unsure whether your document qualifies, you can contact us for a free document check before placing your order.

We see the same issues come up regularly when customers try to apostille a medical letter. Understanding these pitfalls in advance can save you time and frustration.

We pre-check every document before sending it to the FCDO apostille office, so if there is a problem, we will let you know before any submission is made.

A wide range of medical letters can be apostilled for use abroad. Here are some of the most common examples we process:

• Fit-to-work letters confirming a person’s physical or mental fitness for employment overseas
• General health certificates often required for visa applications or residency permits
• Visa medical letters used to support immigration applications in Hague Convention countries
• Adoption medical reports required as part of intercountry adoption proceedings
• Letters confirming ongoing treatment or medication for individuals relocating abroad
• Specialist referral summaries needed by overseas healthcare providers

If your document is specifically described as a medical certificate, the same eligibility rules apply. The key factor is always that a GMC-registered doctor has signed the document and their details are verifiable.

For more detail on whether you need to send the original or whether a copy would suffice, see our guide on legalising original or copy documents. In most cases, the FCDO will require the original signed letter.

While the FCDO apostille itself is a standardised certificate recognised across Hague Convention member countries, the receiving authority in your destination country may have additional requirements. These can vary significantly, so we always recommend checking with the organisation requesting your document before you order.

Common additional requirements include:

• Recency of issue: Many institutions require the letter to be dated within three to six months of submission. The FCDO does not set a strict expiry, but the requesting authority often does.
• Specific wording or format: Some countries or organisations require particular phrases, such as confirmation that the individual is “free from communicable diseases” or “fit to travel.”
• Certified translation: If the destination country does not use English as an official language, you may need a translation alongside the apostille.
• Embassy attestation: A small number of countries that are not members of the Hague Convention may require embassy legalisation in addition to an apostille.
• Notarised copy: In certain situations, a notarised copy of the medical letter may be accepted instead of the original. This typically involves a solicitor or notary certifying the copy, which is then apostilled. This is not best practice.

If you need both an apostille and a translation, we can help.

Requirements can vary depending on the destination country, requesting authority and document type. We can advise on the apostille and legalisation process for UK documents, but you should confirm the exact requirements with the organisation requesting your document before placing an order.
