Employer notice of dismissal letter: Belgian template
As an employer you end an employee's contract with a notice period. For you the form rules are stricter than for the employee: a mistake makes the notice void. This model contains the mandatory mentions; you fill in the term yourself.
When do you use this model?
Use this model when you end an open-ended contract with a notice period to be worked. If you end the contract immediately with compensation in lieu of notice, other rules apply and this model does not fit.
Form requirements
- Notice is given in writing and states the start and the length of the notice period. If either is missing, the notice is void. According to the FPS Employment, the termination still stands, the contract ends at once and the party giving notice owes compensation in lieu of notice.
- If the employer gives notice, this can only be done by registered letter or through a bailiff. Handing over the letter at work is not enough, except in companies under the joint committee for inland navigation. Notice in any other form is void; the employee cannot waive that nullity and the court establishes it of its own motion.
- A registered letter only takes effect on the third working day after the date it was sent. Every day of the week counts as a working day except Sundays and public holidays.
- The notice period starts running on the Monday after the week in which notice was given.
- How many weeks your notice period lasts depends on your seniority and on who gives notice. The model therefore leaves the term open: calculate it with the calculator and fill in the result.
The model
Mind the language. The legally required language depends on where you work, and a document in the wrong language can be void. Further down this page you can read which rule applies where. This English version is a reading aid: send the version in the language your workplace requires.

Tips
- Work from the sending date: count three working days from the day the registered letter leaves, and base the week of notification on that.
- Have your payroll provider check the letter before you send it, especially the seniority and the calculation of the term.
Which language is required?
Which language is mandatory depends on where the operating site you work at is located. In the Dutch language area it is Dutch (Flemish language decree of 19 July 1973), in the French language area it is French (decree of the French Community of 30 June 1982). Both govern the language of social relations between employer and employee.
In Brussels-Capital and in the Flemish municipalities with language facilities, the federal law on the use of languages in administrative matters applies. In Brussels, documents for staff are drawn up in Dutch or in French depending on the employee's language; in the municipalities with facilities, in Dutch.
Both decrees provide that documents contrary to the language rules are void and that the court establishes that nullity of its own motion. The Flemish decree adds that the annulment may not harm the employee. In Brussels, documents in the wrong language must be replaced.
Frequently asked questions
Can I simply hand over the notice letter?
No. As an employer you only give notice by registered letter or through a bailiff. Handing it over is not enough, except in companies under the joint committee for inland navigation.
What if the start or the length is missing?
Then the notice is void. According to the FPS the dismissal stands, but the contract ends at once and you owe compensation in lieu of notice.
In which language do I write the letter?
That depends on the operating site where the employee works: Dutch in the Dutch language area, French in the French language area, and in Brussels Dutch or French depending on the employee's language. Documents contrary to the language decrees are void.
