Travel Cancellation Insurance: Which Medical Documents to Provide and When

Travel cancellationUpdated 17 June 2026

When illness or an unexpected health problem stops you from travelling, cancellation insurance may cover part or all of the money you committed, provided you build a solid file. The medical document is the centrepiece, but its quality, its consistency and respecting the filing deadlines often decide the outcome. Here is how to gather the right documents and reduce the risk of a refusal.

Which medical documents does your insurer expect?

Most travel cancellation policies ask for objective medical proof of the event that prevents you from travelling. The item most frequently requested is a medical certificate issued by a doctor registered with the medical board, stating that you are unable to take the planned trip and specifying the period concerned. Depending on the policy, other documents may complete the file.

Requirements differ from one insurer to another, so it is essential to read your contract or general terms before assembling the file. As a guide, the documents often requested include the following:

Within what deadlines must you file the claim?

Meeting the filing deadlines is one of the most sensitive points. Most contracts require you to report the event to your insurer very quickly after it occurs, often within a number of days set out in the general terms. Failing to respect this deadline may, depending on the policy, reduce or even jeopardise compensation.

As a precaution, the safest approach is to notify your insurer as soon as you know you will not be able to travel, without waiting until you have gathered every document. You can open the file first and complete the supporting documents afterwards, within the stated deadline.

The medical certificate is best issued as early as possible, ideally when the health problem arises. A certificate dated within the relevant period is generally given more weight than a document drafted long after the events. The Certi-Fly service lets you obtain a travel cancellation medical certificate signed by a doctor registered with the medical board, after a medical assessment carried out by phone or WhatsApp, which helps you stay within these time windows.

Consistency of dates and information: often the deciding factor

Insurers check the consistency between the various dates in your file. An apparent inconsistency can lead to requests for additional documents, or even a refusal. It is therefore worth making sure that the whole file tells a clear and logical timeline.

The points to check relate in particular to the sequence of dates:

Keep your evidence and build a complete file

A claim is sometimes refused simply because a document is missing or has not been kept. Get into the habit of keeping a copy of every document you send, as well as a record of your exchanges with the insurer.

A few good practices help you present an orderly and defensible file:

Reducing the risk of refusal: useful reflexes

No service can guarantee that a claim will be accepted, because the decision belongs to the insurer and depends on your contract. However, a precise, dated and consistent file clearly reduces the grounds for dispute. The aim is to present the insurer with a clear, complete and verifiable request from the very first submission.

Read your policy's guarantees and exclusions carefully: some situations may not be covered, and it is better to know this before assembling the file. If you have any doubt about a clause, do not hesitate to ask your insurer directly. For the medical part, a clear certificate issued by a doctor registered with the medical board, such as the one offered by Certi-Fly, helps make the file easier to read.

Frequently asked questions

Is a medical certificate enough to get my trip refunded?

The medical certificate is a centrepiece, but on its own it does not guarantee compensation. The decision rests with your insurer and depends on the guarantees, exclusions and deadlines set out in your contract. A clear, dated certificate does, however, make your file easier to assess.

When should I report my cancellation to the insurer?

It is best to notify your insurer as soon as you know you will not be able to travel, without waiting until you have gathered every document. Contracts often impose a specific deadline after the event occurs: check your general terms for the exact window.

What should I do if the dates in my file seem inconsistent?

Check that the timeline is logical: the dates the policy was taken out, the health problem arose, the certificate was issued and the claim was filed should follow one another consistently. If there is a gap, add a written explanation and, if needed, a supporting document provided for by your contract.
