Co-ownership Trade Union Council

Verified 28 May 2025 - Directorate for Legal and Administrative Information (Prime Minister)

The trade union council is a mandatory body in all joint owners' union. It plays an important role in linking the trustee and co-owners. The board of trade unions provides an advisory, decision-making and supervisory function for the liquidator. Its organization and operation are regulated by law, but co-ownership retains freedom of organization. We explain the information you need to know.

The union council should not be confused with the condominium trustee.

In principle, the constitution of a trade union council is obligatory. This is a legal obligation. It is therefore not necessary that the co-ownership rules mention or not the existence of a trade union council.

However, there are 3 exceptions to this legal obligation:

  • When the joint owners' union waive the formation of a trade union council. This waiver must be voted at the general meeting of the co-owners at the double majority (Article 26). The co-owners are not, however, definitively bound by this decision. They may thus choose, at another general meeting, to set up a trade union council. This decision shall be voted on by the absolute majority (Article 25).
  • When no candidate presents himself or does not obtain the required majority. In this case, the union council may be appointed by the judge, at the request of the trustee or a co-owner.
  • In the small condominiums.

All co-owner, their ascendants or descendants, partners in the event of a civil property business, buyers or purchasers on a fixed-term basis (variant of life-buying), their spouses, partners linked to them by a Civil partnership, their legal representative, or their usufructuaries may be members of the trade union council.

This may be a natural person (individual) or a legal person.

Where a legal person is appointed as a member of the trade union council, it may be represented there, either by its legal or statutory representative or by a specially authorized proxy holder (person with the powers of a proxy holder) for that purpose.

Warning  

When the trustee is a professional trustee, the trustee, his servants, their partner spouses linked to them by a Civil partnership, concubine, ascendant or descendant, parents in collateral line up to 2è degree, even if they are joint owners, partners or purchasers in the long term (variant of life purchase), may not be members of the trade union council.

To be a member of the union council, you must be appointed by the general meeting of the co-owners. This appointment shall be voted on by the absolute majority (so-called majority of Article 25).

If an absolute majority is not obtained, but the candidature has received at least one third of the votes of all the co-owners, a new vote may take place immediately, at the simple majority (so-called majority of Article 24).

Each member of the trade union council may be nominated:

  • Prior to the general meeting, the person must inform the trustee before sending the summons
  • During the general meeting.

Please note

The co-ownership rules may impose specific rules to govern the applications of members of the trade union council.

The general meeting of the co-owners elects the members of the union council, one by one.

In principle, the trade union council is a collegial body composed of several members.

No text does not, however, impose a minimum number of members to be composed of the trade union council.

The number of members is determined by the general meeting or the condominium rules. In practice, however, a minimum number of 3 members is recommended.

FYI  

One or more alternate members may be appointed under the same conditions as full members.

Trade union council assistance mission

The union council must assist the trustee. It thus gives its opinion, spontaneously or at the request of the trustee, on all questions concerning the joint owners' union.

The trustee must obligatory consult the trade union council in 4 cases:

  • Preparation of theagenda of the general meeting of the co-owners
  • Urgent work carried out at the trustee's initiative to save (preserve) the building
  • Appointment of a provisional administrator (case of syndicate of co-owners in difficulty)
  • Conclusion of contracts and contracts exceeding a certain threshold (e.g €2,000), voted in the General Assembly.

Mission of the trade union council to call for competition for trustee contracts

Prior to the general meeting, the trade union council must carry out a competitive tendering several draft trustee contracts. In practice, this involves interviewing several trustees in order to obtain:

  • A draft contract
  • A fact sheet on the price and the services offered.

These elements allow the co-owners to compare the different proposals.

This call for competition applies in the case of the appointment of a new liquidator (revocation or non-renewal) or a renewal of the trustee's contract already in place. It makes it possible to anticipate the trustee's departure or retention.

FYI  

If there has been no call for competition, the appointment of the trustee shall remain valid.

The trade union council may, however, be exempted from this task of calling for competition by a decision adopted by the absolute majority.

Supervisory mission of the trade union council

The trade union council oversees all management of the condominium trustee, including:

To carry out this mission, all members of the union council can consult the documents relating to the management of the trustee and the administration of the condominium (e.g. emails, letters, registers). They are free to make copies of these documents.

This examination of the documents thus enables the trade union council to exercise effective control.

FYI  

The documents must be forwarded by the trustee. In the event of no transmission beyond one month from the request of the trade union council, €15 per day of delay shall be deducted from the liquidator's annual flat-rate remuneration. These penalties are deducted from the trustee's remuneration when the accounts to be submitted to the AG are drawn up.

Delegation of powers by the trade union council

The general meeting of the co-owners may delegate to the trade union council, composed ofat least 3 members, the power to take decisions by simple majority.

Examples of such decisions include decisions on the day-to-day administration of the building (setting of heating periods, rental of the caretaker's lodge, etc.) or on the maintenance of the building (felling of a tree for safety reasons, cleaning, snow removal, etc.).

However, some subjects are excluded from this delegation. These are:

  • Approval of accounts
  • Determination of the estimated budget
  • Adaptation of the co-ownership rules necessitated by legislative and regulatory changes.

This delegation of powers must be voted by the syndicate of co-owners at the general meeting of the co-owners at the absolute majority.

The duration of the delegation of powers shall be maximum 2 years. She's renewable by a decision of the general meeting of the co-owners.

FYI  

Decisions taken by the trade union council in the course of its delegation duties shall be adopted by a majority of its members. If there is a tie, the President of the union council has the casting vote (upper).

The general meeting shall fix the maximum amount granted to the trade union council to carry out its delegation duties. The amounts allocated are:

  • Be included in the estimated budget,
  • Be fixed at the general meeting, where they relate to expenditure on works not included in the provisional budget.

Liability action against the liquidator

The President of the Trade Union Council may, in the case of failure or inaction of the liquidator, take legal action against the liquidator to seek compensation for the damage suffered by the syndicate of co-owners.

To do so, it must obtain an express delegation from the General Assembly, voted in the absolute majority. In practice, this means that the resolution passed must mention the agreement of the co-owners for the president of the union council to take legal action against the trustee.

The operation of the trade union council shall be determined by the co-ownership rules. If nothing is provided for in the co-ownership regulation, the rules on the organization of the trade union council (number of members, duration of the mandate, the existence or not of alternates, the holding of meetings, voting etc.) are fixed by the general meeting of the co-owners, which votes on the simple majority.

Once elected, the members of the trade union council elect their president among them.

The president's tasks are to:

  • Prepare and convene union council meetings. He moderates the debates, divides the tasks between the members.
  • Forward the union council's opinions to the trustee, co-owners or third parties. He receives the information from the trustee and distributes it to the advisors.
  • Convene General Meeting annual co-owners in the event of the trustee's inaction. He may, on delegation from the general meeting of the joint owners, appeal against the liquidator in the event of his failure or inaction for the damage suffered by the joint owners' union.

Each year, the trade union council reports to the general assembly on the execution of its mission by means of an activity report attached to the meeting notice.

The members of the trade union council are not paid. They shall perform their duties free of charge.

The expenses necessary for the execution of their mission shall be paid by the co-owners, within the framework of the current expenses included in the provisional budget.

The members of the trade union council are elected for a term of office up to 3 years. The term of office shall be renewable by a vote in the General Assembly of the absolute majority.

The term of office of the members of the trade union council shall end in the following ways:

  • By resigning. In practice, the president of the union board and the trustee must be informed of the resignation.
  • By the revocation of their mandate. This decision is taken by the co-owners at the absolute majority
  • When they lose the status that allowed them to be a member of the union council (sale of the lot, death, etc.).

Please note

The trade union council is no longer validly formed when more than ¼ quarter of the seats are vacant, whatever the cause of this vacancy (illness, resignation, revocation...). However, there is no need to re-elect the entire union board, as the incumbents retain their mandate. The general meeting of the co-owners must be convened only to replace the members whose seats have become vacant.

Each member of the trade union council may commit his civil liability or penal in the performance of its tasks, vis-à-vis the syndicate of co-owners, co-owners or third parties. In practice, only serious misconduct is liable to be punished on account of the voluntary nature of the duties of a member of the trade union council.

The syndicate of co-owners must take out insurance for each member of the trade union council to cover their civil liability.
