Union of co-owners

Verified 09 June 2026 - Public Service / (Prime Minister)

What is the syndicate of co-owners? The syndicate of co-owners is an organ of the condominium. It is composed of all the co-owners of a building or a real estate complex. He is responsible for common areas and makes decisions in the interest of the property and its occupants. We present you the information to know.

Please note

The syndicate of co-owners should not be confused with the syndic of co-ownership, responsible for managing the building and executing the decisions taken by the co-owners.

The syndicate of co-owners exists automatically, without any administrative formalities (neither declaration nor registration), as soon as an immovable or a group of immovable is divided into at least 2 batches, belonging to different owners and each comprising a privative part and one share of common areas.

The syndicate of co-owners is thus born when the co-ownership appears, that is to say:

  • From 1er transfer of ownership (sale) of a batch in case of co-ownership of an existing built building
  • From the delivery of 1er lot for buildings to be built.

FYI  

The syndicate of co-owners exists even in the absence of registration of co-ownership.

To justify the existence of the syndicate of co-owners, it is sufficient to produce the condominium rules and to indicate the name of the trustee in charge of the management of the building.

Yes, the syndicate of co-owners has its own rights.

This is because the syndicate of co-owners is a legal person separate from co-owners. In other words, the group constituted by all the co-owners has a legal personality independent of the members which compose it.

FYI  

The syndicate of co-owners is a non-professional legal person since he does not engage in a commercial, industrial, craft, liberal or agricultural activity. He retains this status even if he is represented by a professional trustee.

As a legal person, it has:

  • An own heritage distinct from that of the co-owners
  • The ability to take legal action, including against certain co-owners
  • Management and decision-making powers limited by its purpose (conservation, improvement of the building, administration of common areas) and by the individual rights of co-owners.

These rights are therefore unique to the union, even if they are exercised to defend a private collective interest (the interest of all co-owners).

Please note

As it is not a natural person, the syndicate of co-owners is not treated as a « consumer ».

Therefore, it does not benefit from:

  • Protection against unlawful or unfair terms in contracts with third parties (service providers, suppliers, etc.)
  • The prescription biennial which limits to 2 years the period of action of the creditors professionals, in particular in the context of the recovery of unpaid invoices.

The trade union is identified by:

  • Sound name. In practice, the name is fixed by the condominium rules. In the absence of a specific name, the syndicate of co-owners is designated by the address of the immovable.
  • Sound seat. The registered office is generally the postal address of the location of the immovable unless the co-ownership by-law indicates that it is the domicile of the syndic of co-ownership. All notifications, formal notice or meanings of interest to the syndicate of co-owners must be made at its headquarters or at the home of the trustee.
  • And his registration the National Register of Condominiums (RNC).

FYI  

Information on the identification and organization of the condominium is mentioned in the summary sheet from the building.

The syndicate of co-owners may have 2 shapes different:

  • Ordinary when he has chosen a trustee professional or non-professional (volunteer) to manage and administer the building. This is the most preferred form in practice
  • Or cooperative. We're talking about a cooperative union. The building is then managed and administered by the members of the union council, designated at the general meeting by the co-owners.

In the event that the syndicate of co-owners has the cooperative form, it is mandatory from:

  • Establish a trade union council, except for small condominiums (condominium that includes no more than 5 lots for housing, office or commercial use or when the average forecast budget over a period of three consecutive years is less than €15,000 ). The President of the trade union council, elected by its members, acts as a syndicate of co-ownership
  • Appoint an auditor (natural or legal persons, co-owners or not).

The adoption of the cooperative form must be voted by a majority of all co-owners present, represented and absent (called majority of Article 25).

The syndicate of co-owners has 3 missions.

Conservation of the building

The syndicate of co-owners has the obligation to keep the building in good condition by avoiding damage and by having the necessary maintenance and repair works carried out.

Building Improvement

The syndicate of co-owners may decide to make improvements to the common parts or installations of the building. For example, it can vote on works to improve the comfort of occupants, increase the safety or energy performance of the building, renovate or beautify common areas.

Administration of the common parts of the building

The syndicate of co-owners must also manage the common areas and the collective services of co-ownership.

To this end, it shall:

  • Ensures compliance with condominium rules by co-owners, tenants and third parties
  • Vote in general assembly the conclusion of all contracts necessary for the proper functioning of the condominium (for example, trustee's contract, maintenance contract for common equipment or security systems, cleaning contract, insurance contract, works or renovation contract).

FYI  

Contracts are concluded and signed on behalf of the syndicate of co-owners through its trustee.

In order to carry out its missions, the syndicate of co-owners has several powers. In particular, it:

  • Establishes the condominium by-law, if it does not pre-exist to the condominium, and modifies it according to the needs of the condominium and legal or regulatory obligations
  • Sets the conditions of use and maintenance of common areas
  • Designates or revokes the trustee
  • Designates the members of the union council
  • Vote on provisional budget every year
  • Constitutes the mandatory works funds
  • Concludes contracts in the name and on behalf of the condominium
  • Performs acts ofacquisition,alienation or the creation of rights (e.g. citizenship or easement) that will increase the common parts of the building
  • Decides on the works on the building (maintenance and conservation works, improvement works, etc.)
  • Can use a group loan to finance works on common areas
  • Acts in court on behalf of the condominium. He can initiate legal action against a third party (supplier, service provider, craftsman, neighbor ...) or co-owner. It can also defend the interests of the condominium when it is sued in court.

Please note

The powers of the syndicate of co-owners are exercised in compliance with the clauses of the co-ownership regulation and the destination of the building.

The syndicate of co-owners may be held liable in 2 cases.

Common parts causing the damage

The syndicate of co-owners is fully responsible for damage caused to co-owners or third parties having their origin in common areas from the building. This is an automatic liability that does not require proof of fault on its part.

In this case, it is sufficient for the victim to prove that the damage complained of comes from the common parts of the building.

Example :

Structural disorders or subsidence of the building related to water infiltration from common networks, damage caused by a lack of maintenance or a defect in the construction of the common parts or accidents caused by common equipment (lifts, dikes, safety devices, etc.).

Other

The syndicate of co-owners is also liable, with respect to co-owners, employees or third parties, for all damages resulting from:

  • Of its misconduct in the management and conservation of the building
  • Persons (employees of the condominium) that he has in his custody (janitor, caretaker, building employee)
  • Objects he has in his custody
  • Or the damage caused by the ruin of the building, when it arrived as a result of the lack of maintenance or by the defect in its construction (for example, malfunction).

In these cases, the victim must prove the existence of a fault of the syndicate of co-owners.

The syndicate of co-owners takes legal action to defend the collective interests of the building.

For example, it may bring an action before the court against a third party (supplier or provider of co-ownership) in the event of difficulties related to the performance of a contract (absence or poor performance of the service) or against a co-owner in the event of abnormal neighborhood disorder or unpaid charges.

The syndicate of co-owners is obliged to act through the trustee in co-ownership or the president of the trade union council.

Legal action through the trustee

The syndicate of co-owners is represented in court by his current trustee. While, in principle, the trustee must first be authorized by the general meeting to take legal action, there are certain exceptions for which he may directly bring the matter before the court.

Trustee's authorization

The trustee cannot take legal action on behalf of the syndicate of co-owners without having been there authorized by a decision of the general assembly.

This authorization shall state:

  • The subject of the legal claim (for example, an action to request reimbursement of an invoice)
  • The persons concerned
  • And the nature of the action (for example, an action in interim relief).

FYI  

It is necessary to fill in all these elements because the power granted to the trustee is limited to what is in the resolution.

Whatever the nature or purpose of the legal claim, the authorization granted to the trustee must be adopted by a majority of the votes of the persons present, represented or who voted by post (majority referred to in Article 24).

Authorization waiver

There are several cases where prior authorization from the General Meeting will not be required.

These are:

  • Actions to recover the expenses owed by the co-owners
  • Actions for recovery of a claim of the syndicate of co-owners
  • Means of enforcement (seizure of movable property, entry of remuneration, input-allocation), with the exception of foreclosure
  • Protective measures (e.g. the request for preservation of a sum of money)
  • Opposition to works that allow electric cars to be recharged normally
  • Applications that fall within the powers of the referred (for example, a request for forensic expertise)
  • Legal actions in which the syndicate of co-owners is defendant
  • The appointment of an ad hoc representative or provisional administrator in the case of a condominium in difficulty.

Please note

If the trustee can act directly, without the prior consent of the condominium, he must account for the actions taken at the next general assembly co-owners.

Consequences of lack of authorization

The absence of authorization from the trustee will result in inadmissible the application made by the trustee on behalf of the syndicate of co-owners. However, to avoid the sanction of inadmissibility, the syndicate of co-owners can validate the initiative of the trustee during a meeting. He must do so before the judge makes his decision.

Warning  

Only co-owners against whom legal action is taken by the trustee can invoke the trustee's lack of authorization to take legal action.

Legal action through the president of the trade union council

The syndicate of co-owners may also act through the president of the union council, in the event of inaction or inaction of the trustee.

On authorization express of the general assembly which he himself summoned, the president may bring legal proceedings against the trustee in office in order to obtain compensation for the damage suffered by the syndicate of co-owners.

In the event of a conviction, damages are paid to the syndicate of co-owners.

Please note

Where the co-ownership does not have a union council, this action may be exercised by one or more co-owners representing at least one quarter of the votes of all the co-owners.

The syndicate of co-owners disappears in 3 cases :

  • By unanimous decision of all co-owners to end the state of co-ownership of the immovable. This hypothesis concerns buildings composed of several buildings and for which the division into separate ownership is possible, that is to say when one or more buildings belong to a single co-owner. This or these buildings will be removed from the syndicate of co-owners to form an individual property. This division into autonomous buildings may also be imposed by the judge, at the request of the'provisional administrator, in the case of condominiums in difficulty.
  • By total disappearance of the building in the event of material destruction of the building (collapse, fire, explosion, flood, ruin due to obsolescence) and on the condition that the co-owners decide not to rebuild the building at a general meeting
  • By the meeting all batches in the hands of a single owner. There is then a reconstruction of a unified private property. This situation results from the acquisition of all the lots by the same natural or legal person, of a business intake of all the lots of the building or theexpropriation of the entire building for reasons of public utility.
