The syndic of your co-ownership: appointing, monitoring and changing them
You have just bought an apartment, you sit on the co-ownership council, or the general meeting has to choose a syndic. Here is what a syndic does, the two ways the role can be carried out and the levers you have.

Updated on 25.09.2026- Syndic duties: checking that yours carries out all 16 legal tasks
A decision that was voted on still has not been carried out, and you wonder whether your syndic is really doing the job. Here are the syndic's legal duties, in the order in which they come up, with the deadlines to watch and what you can demand.
- Volunteer syndic: deciding whether it suits your building
The syndic's contract is coming to an end, the fees are a burden, and someone at the general meeting suggests: “Why doesn't one of us take it on?” Here is how to judge, before the vote, whether a volunteer syndic will hold up in your building.
- Professional syndic: checking BIV/IPI accreditation, the contract and the mandate
An estate agent offers to manage your building, or already manages it without you quite knowing what to ask of them. Here is how to check their accreditation, read their contract and keep them in check until the end of the mandate.
- How to become a volunteer syndic: from the general meeting vote to registration with the KBO/BCE
The general meeting has just appointed you syndic of your building, or is about to. Here are the steps in the right order, from the vote to taking over the file, so that you are in order from the start.
- Volunteer syndic pay: working it out, getting it voted, declaring it
You manage the building, the hours are piling up and you wonder whether you can be paid. You can, provided the amount is set out in a written contract approved by the general meeting. Here is how to propose it without putting a foot wrong.
- Syndic liability: proving the fault and obtaining compensation
Funds badly held, a leak nobody deals with, a file never handed over: you suspect the syndic is at fault. Here is who he answers to, what has to be proved and how the association can obtain compensation, whether he is a professional or a volunteer.
- How to change syndic: procedure, timeline and handover of the records
Your syndic is no longer up to the job, or their contract is coming to an end. The vote is only one step: here are the timeline, the items to put on the agenda and the handover of the file, which decides whether the change succeeds.
- Dismiss the syndic: voting it at the GM, handling compensation and resignation
Your general meeting wants to part with the syndic before his mandate ends, or he is the one announcing his departure. Here is how to vote on the dismissal, gauge the risk of compensation, plan the successor and respond to a resignation.
- Syndic contract: reread it clause by clause before you sign
The prospective syndic has given you their draft contract, and the meeting has to approve it. Here is what the Civil Code requires, the terms to insist on and the clauses to reread before signing, whether the syndic is a professional or a volunteer.
Water damage in the stairwell, a unit being sold and a notary waiting for an answer, a general meeting decision that is slow to be implemented: in each of these situations, the person you turn to is the syndic. Decisions are taken at the general meeting (GM). Someone then has to carry them out, pay the invoices, keep the accounts, call the insurer and answer the notary. That someone is the property manager, known in Belgium as the syndic (syndicus). The Belgian Civil Code makes the syndic a mandatory body of the owners' association (VME/ACP)GlossaryLegal entity that brings the co-owners together and whose sole purpose is the preservation and management of the building. It acquires legal personality as soon as a first unit is transferred, provided the deed of division and the co-ownership regulations have been transcribed. See the glossary, also referred to in everyday language as the co-ownership manager.
If you are not satisfied with your building's syndic, or if the general meeting has to appoint one, start by knowing what the law expects of them. The rules come from Book 3 of the Civil Code (Articles 3.78 to 3.100) and from the professional obligations laid down for estate agents. They are federal: they apply in the same way in Flanders and in Brussels.
What is the role of a co-ownership syndic?
Article 3.89 of the Civil Code sets out a list of duties that the syndic performs whatever powers the house rules (ROI)GlossaryRules drawn up by private agreement that set out at least how the general meeting operates, how the syndic is appointed and the fortnight in which the ordinary general meeting is held. They are kept at the association's registered office and can be consulted free of charge. See the glossary give them. These include carrying out the general meeting's decisions, protective measures, managing the funds in separate accounts, representing the association in legal proceedings, keeping clear accounts and preparing the budget estimates.
On top of that come transparency duties: giving access to non-private documents, presenting several quotes when the general meeting has set a tendering threshold, and asking for prior authorisation before entering into a contract with a close relative. The details, point by point, are on our page on the role and duties of the syndic.
The syndic is not the boss of the building. They act on behalf of the owners' association, remain solely responsible for their management and may not delegate their powers without the general meeting's consent. For cases where a fault is committed, see syndic liability.

Volunteer or professional syndic: two statuses, the same obligations
The law does not create two categories of syndic. The duties in Article 3.89 apply to everyone. The difference lies in who carries them out. Our view: the choice between the two is practical before it is legal. It depends on the time available, the skills present in the building and the oversight the co-ownership can organise.
A volunteer syndic is usually a co-owner who manages their own building, without making it their profession. This arrangement is found mainly in small co-ownerships. It takes time and rigour, because the accounting, the deadlines and the public notice requirements are identical. See volunteer syndic and, if you are thinking of taking on the role, becoming a volunteer syndic.
A professional syndic works on a self-employed basis and must be registered with the Professional Institute of Estate Agents (IPI/BIV). They are bound by a code of ethics and subject to disciplinary oversight. The full picture is on the page on the professional syndic.
| Volunteer syndic | Professional syndic | |
|---|---|---|
| Legal duties (Art. 3.89) | Identical | Identical |
| IPI/BIV approval | Not required for a co-owner managing their own building | Mandatory |
| Liability insurance | Mandatory, at the association's expense if the mandate is unpaid | Mandatory |
| Registration of the mandate with the KBO/BCE | Yes | Yes |
| Maximum length of the mandate | Three years, renewable by express decision | Three years, renewable by express decision |
How is the syndic appointed and monitored?
The first syndic may be appointed by the house rules. Failing that, the first general meeting appoints them, and if nobody does, the court can step in. After that, the general meeting decides by an absolute majority of the votes of the co-owners present or represented. The mandate never exceeds three years.
Once appointed, the syndic has eight days to post an extract of their appointment at the building entrance. Their mandate must also be registered with the Crossroads Bank for Enterprises. The relationship with the association is based on a written syndic contract.
Oversight lies first with the general meeting, which can dismiss the syndic at any time. In buildings with at least twenty units (cellars, garages and parking spaces not included), a co-ownership councilGlossaryBody made up of co-owners, mandatory in buildings with at least twenty units, excluding cellars, garages and parking spaces. It ensures that the syndic carries out their duties properly. See the glossary monitors how the syndic carries out their duties. When relations deteriorate, three pages take over: changing your syndic, dismissal and resignation of the syndic and, on the budget side, syndic prices in Belgium.
Frequently asked questions
Can a co-ownership function without a syndic?
No. The Civil Code makes the syndic responsible for carrying out the decisions of the general meeting and for representing the owners' association. If no syndic is appointed by the house rules or by the general meeting, the court may appoint one at the request of any co-owner or any third party with an interest (Art. 3.89, § 1, Civil Code).
How long does a syndic's mandate last?
Three years at most. The mandate can be renewed, but only by an express decision of the general meeting (Art. 3.89, § 1, Civil Code). Tacit renewal is not provided for by law.
Does the syndic have to be approved?
Anyone acting on a self-employed basis, as a main or secondary occupation, must be registered with the Professional Institute of Estate Agents (IPI/BIV). A co-owner who manages the building in which they own a unit on a voluntary basis is not subject to this requirement.
Where can I see who the syndic of my building is?
Within eight days of the start of their mandate, an extract of the appointment must be posted at the building entrance (Art. 3.89, § 2, Civil Code). The mandate is also registered with the Crossroads Bank for Enterprises (KBO/BCE), which can be consulted online.
