Medical certificate or simple proof: what cancellation insurance really requires for a health reason

Travel cancellationUpdated 17 June 2026

When a health problem forces you to give up a trip, one question keeps coming up: is a short note of explanation enough, or do you need a genuine medical certificate? In most cases, cancellation insurance expects a document dated and signed by a doctor registered with the medical board. This article explains why, and what such a document usually contains.

Personal proof or medical certificate: why they are not the same

Personal proof (a message, an email, a handwritten note describing your condition) rests on your testimony alone. It commits no one and does not allow the insurer to verify the reality or the medical nature of the obstacle. That is why it is rarely accepted on its own for a health-related claim.

A medical certificate, by contrast, is a document drawn up and signed by a doctor registered with the medical board, after an examination. It attests that a health reason existed on a given date and that it was, from a medical standpoint, incompatible with departing or continuing the trip. It is this professional, binding character that makes it the document generally expected by airlines and travel insurers.

In other words, what is in question is not the seriousness of your situation, but how it is attested: the insurer needs an enforceable document from a qualified third party, not a statement that anyone could write freely.

What cancellation insurance actually expects for a health reason

Conditions vary depending on the company and on your contract, and it is always worth re-reading your policy before taking any steps. Even so, a few requirements come up very frequently when a health reason is invoked.

Why a doctor-signed certificate is generally expected

Cancellation insurance relies on verifying an event covered by the contract. For a health reason, only a qualified professional can observe and state the medical reality of the obstacle. The certificate provides the objectivity that a simple personal statement cannot offer.

The document must also respect medical confidentiality: a certificate intended for an insurer in principle describes the inability to travel and its period, without necessarily detailing the full diagnosis. It is for the doctor to judge which wording suits the situation and the intended use.

Finally, a certificate issued by a doctor registered with the medical board, dated and signed, is more readily recognised when a claim is examined. This does not guarantee compensation, which always depends on the cover and exclusions in your contract, but it brings together the element that insurers most often expect.

The usual wording of a travel cancellation certificate

A travel cancellation medical certificate is not a form you fill in yourself: it must be written and signed by a doctor after an examination. For information, it generally includes the following elements, which the doctor adapts to the case and to medical confidentiality.

How Certi-Fly issues your certificate

Certi-Fly is an online service that lets you obtain a travel cancellation medical certificate signed by a doctor registered with the medical board, issued within 24 hours. The medical examination takes place by phone or WhatsApp, with video available as an option when the situation calls for it.

The doctor first assesses whether the situation justifies a certificate and, where appropriate, writes the suitable wording. The document is then sent to you to attach to your file with your insurer or the airline. Certi-Fly does not replace either your contract or your insurer's decision: it provides the medical document generally expected, with no promise of reimbursement.

Frequently asked questions

Is a simple note from my doctor enough to cancel my trip?

Usually not. Insurers expect a medical certificate that is dated, signed and drawn up after an examination. An informal note or personal testimony is rarely sufficient for a health-related claim. Check the exact requirements in your contract.

Must the certificate spell out my illness in detail?

Not necessarily. While respecting medical confidentiality, a certificate intended for an insurer in principle describes the inability to travel and its period, without detailing the entire diagnosis. It is for the doctor to judge the appropriate wording.

Does the certificate guarantee reimbursement of my trip?

No. Reimbursement depends on the cover, conditions and exclusions in your contract, as well as on your insurer's decision. The certificate provides the medical document generally expected, but guarantees no compensation. Consult your policy.

How does the examination with Certi-Fly work?

The medical examination takes place by phone or WhatsApp, with video as an option. A doctor registered with the medical board assesses the situation and, if it is justified, draws up and signs the certificate, usually issued within 24 hours.
