Declaration of work disability

You are incapacitated if you are unable to work due to an illness, accident or pregnancy. Don't forget to complete your declaration.

The first step in completing your declaration is to correctly complete and submit the certificate ('Confidential' form).

Request a certificate

You can download the certificate of disability or request it online .

Complete certificate

Complete the document correctly and completely .

  • Complete the top section yourself and stick a yellow sticker on the certificate. Please indicate that this concerns the onset of incapacity for work.
  • Your doctor must complete and sign the second part in full.
  • If you are incapacitated for work for a full week, your doctor must indicate Sunday as the end date. 

How do you declare your disability?

Has the certificate been completed by you and your doctor? Then submit your declaration of disability to CM. This can be done online or in writing.

Do you live or work abroad? Then other conditions apply.

When to report?

Do you want to avoid a sanction? Then you must notify CM in time if you become incapacitated for work, or if you remain incapacitated for work after your period of recognition. The term depends on your status. You do not have to provide CM with the certificate intended for your employer.

Late declaration

If you notify CM too late when filing the first declaration or extension of your disability, you will lose ten percent of the benefit for the period of lateness.

In certain situations you can submit an application to the National Institute for Health and Disability Insurance (Riziv) to have the sanction lifted .

To lift the sanction, you must meet two conditions.

  • The loss of income due to the late declaration amounts to more than 25 euros.
  • You are in one of the situations below:

After the declaration

After CM has received your correctly completed declaration, the advising doctor will assess your disability. You will receive that decision in writing. You will also receive the following documents:

  • Information sheet : this sheet is used to calculate your benefit. Complete it and return it to CM as soon as possible. This can also be done digitally .
  • Blank certificate of incapacity for work : keep this document. You need this to possibly extend your recognition or to file a new declaration if you become ill again.
  • Proof of return to work or unemployment : you must complete and sign this if you resume work or unemployment before the end of the recognition period.
