What is the purpose of condominium registration?
Verified 11 March 2026 - Public Service / Directorate of Legal and Administrative Information (Prime Minister)
The registration of condominiums consists in registering each syndicate of co-owners in a national registration register maintained by the National Housing Agency (Anah). It facilitates public authorities' knowledge of the state of condominiums. Likewise, it allows the implementation of actions to prevent malfunctions and identify fragile or degraded condominiums.
A condominium must be registered for several reasons.
Knowledge tool for public authorities
The information declared when registering a condominium, or when updating it, allows the State and local authorities to:
- Know the financial situation of each condominium (for example the level of loads unpaid or the existence of a work fund)
- Know the main technical characteristics of the buildings (e.g. period of construction, number of buildings/floors, presence of elevators and heating systems, existence of domestic hot water or ventilation system, mandatory technical diagnostics, etc.)
- Identify fragile condominiums or difficulty to put in place, if necessary, accompanying measures.
Means of combating undignified habitat
The registration also allows to report the existence of a complaint or a conviction for infringements aimed at sleep merchants. That information must be declared by the liquidator when he is aware of it. They allow public authorities to identify condominiums where abusive practices or unsuitable housing conditions exist.
Example :
These are dwellings:
- Degraded or unsanitary (high humidity, significant mold or water infiltration)
- Without access to drinking water, sewage disposal or sanitation facilities
- Very overcrowded or in a space unsuitable for housing (cellar, garage, attic unfurnished)
- Dangerous for the safety of the occupants
- Without heating.
Transparency and information to third parties
The register of condominiums is also used to inform third parties.
It allows notaries to access all the data mentioned in the register for each condominium, in order to secure sales.
It also offers information on the situation of the condominium (financial situation of the condominium, financial situation of the condominium, etc.) to potential buyers of a property or real estate agents.
The registration is mandatory for any building wholly or partially intended for residential use.
Condominiums fully to usage commercial or office buildings are thus excluded from the registration requirement.
The person responsible for registering the syndicate of co-owners will vary depending on the situation of the condominium.

General case
It's the syndic of condominium which must carry out the initial registration of the syndicate of co-owners and ensure the updating.
FYI
All trustees are concerned, whether they are professionals or volunteers.
Creation of the condominium
In the case of new buildings or an old building placed in co-ownership, the initial registration of the syndicate of co-owners is carried out by the notary.
Condominium without trustee
It's the provisional administrator who registers the condominium in the register.
Condominium in difficulty (for example, in case of unpaid expenses)
It's the ad hoc representative who registers the condominium in the register.
The person who performs the procedure (trustee, notary, provisional administrator or ad hoc agent) is designated as the remote declarant.
The remote registrant must first create an account on the website of the national register of condominiums:
Create an account to register a condominium
FYI
The legal representative must then file documents justifying his function or the mandate that authorizes the person to legally represent the syndicate of co-owners):
- For the professional trustee: signed trustee contract or the signed minutes of the general meeting designating him
- For the cooperative trustee: minutes of the general meeting designating the members of union council and the minutes of the union council electing its president
- For the provisional administrator or the ad hoc trustee: prescription of the judge appointing him.
It must then provide several pieces of information:
- Identification data of the syndicate of co-owners (name, address, date of creation of the syndicate of co-owners and condominium rules, number and nature of batches of co-ownership, form of organization, name of professional or volunteer trustee)
- Financial situation of the condominium (amount of provisional budget, amount of work fund, debts owed by the syndicate of co-owners to suppliers, amount of unpaid payments and number of co-owners debtors, presence of union employees)
- Technical characteristics of buildings which constitute the condominium, in particular those provided for in the mandatory diagnostics (e.g. number of buildings, construction period, energy label, type of heating and type of energy, number of lifts, main collective equipment)
- Information on possible difficulties within the condominium (appointment of an ad hoc trustee or provisional administrator, existence of safeguard measures or unsanitary orderand implementation of the identification and support systems by the prefect or the mayor in case of co-ownership in difficulty)
- Information of the existence of a filing a complaint or conviction the offense of subjecting a person (whose vulnerability or dependency is apparent or known to the perpetrator) to conditions of work or accommodation incompatible with human dignity. The same applies in the case of refusal by the lessor to establish a compliant lease or refusal of authorization to rent a dwelling that does not respect the characteristics of decency, if the trustee is aware of it.
The remote registrant receives a attestation after each registration or update, which allows him to justify that he has fulfilled his obligations.
It is the liquidator or the administrator or the ad hoc representative who must update the information on the register. This update must be made every year.
The update of financial data must be done in the 2 months following the general meeting at which the accounts for the financial year were approved.
Other information (identification, building, procedures, etc.) must be updated in case of change, in principle at the time of the annual declaration. This is the case, for example, of the division of a building resulting in the creation of a secondary union.
The procedure for registering the condominium and the annual update of the information concerning it with the register are free of charge.
The register of registrations (or register of condominiums) is dematerialized. It is held by the National Housing Agency (Anah):
In the absence of registration of the condominium, the Anah or a co-owner or any person with an interest in acting (e.g. a notary in charge of a sale) may give formal notice the trustee to register the condominium. This request is made by registered letter with acknowledgement of receipt.
If the trustee does not register the condominium within a1 month following the formal notice, the Anah may apply a on-call duty of at most €20 per condominium lot and per week of delay. The penalty payment shall apply from the end of the period of one month after the formal notice and until the obligation has been fully fulfilled (registration or updating).
Its amount cannot be invoiced by the trustee to the co-owners.
FYI
The lack of registration or updating of the reported data prevents the syndicate of co-owners from benefiting from certain subsidies (e.g. Anah's help, zero interest eco-loan).
