How to keep the condominium register up to date

What the register must contain by law

Article 1130 number 6 of the Italian civil code requires the building manager to keep a condominium register containing the personal details of each owner and of holders of real or personal rights of enjoyment such as usufructuaries, tenants and borrowers, including tax code and residence or domicile, the cadastral data of each real estate unit, and every piece of information on the safety conditions of the building's common parts and common systems.

In practice the register brings together three distinct blocks: the personal and tax data of the entitled parties, the cadastral references linking each person to their unit, and the technical documentation on the safety status of common parts and systems, including conformity declarations, periodic inspection reports and equipment logbooks. The data most often missing is that of tenants and borrowers, who nonetheless have the right to attend the meeting on matters within their competence and must therefore be recorded just like owners.

Who must report the data and under what obligation

The burden of providing the data lies with the co owners themselves: each one must communicate personal details to the building manager within a reasonable time, together with any subsequent change such as a change of residence, a sale of the unit, a new lease agreement or the death of the owner followed by succession. If a co owner fails to submit the data or submits it incomplete, the manager may formally request it and, absent a response, obtain it independently, charging the cost to the defaulting co owner: the rule exists precisely to prevent the register from stalling because of inertia on the part of those who should keep it current.

Sales and leases are the two events most often missed: a notary is not required to inform the building manager, and landlords rarely report a new lease on their own initiative. Where possible it helps to add an explicit reference to this reporting duty in the condominium bylaws, and to request an update at every meeting notice or whenever certification is needed for a sale.

When and how to update the register

The law sets no fixed schedule for updates, but the register must be revised whenever a relevant change occurs: a change of ownership, a new registered lease or loan for use agreement, a cadastral change such as a unit split, merger or reclassification, or new certification on a common system such as a boiler, lift or electrical system, or on a common part following works.

Practical habits worth adopting: check the register before every meeting notice so invitations go to the parties actually entitled to receive them and in the manner required by article 66 of the implementing provisions; cross check the data against the accounting ledger and the expense allocation plan, because a wrong name produces a charge against the wrong person; and keep a record of update requests sent to co owners, useful if the regularity of a meeting notice is later disputed.

• Change of ownership through sale or succession
• New registered lease or loan for use agreement
• Cadastral change to the real estate unit
• New safety documentation on common systems or parts
• Change of residence or domicile of the owner or tenant

Privacy: which data to process and how to keep it

The condominium register processes personal data, including identifying and property information and in some cases housing related details, and therefore falls within the scope of the GDPR. The building manager, acting as data controller for the management activity, must collect only the data required under article 1130 number 6, avoid requests that go beyond that purpose, limit access to the register to those who genuinely need it for their work, and provide co owners with information on how their data is processed.

UNI 10801, the technical standard defining requirements for condominium management services, refers to the correct keeping of personal and property records as part of service quality: an organized, traceable register with controlled access is not only a legal obligation but a verifiable quality element. Software such as AmministraPro keeps personal data, cadastral information and technical documentation in a single environment with profiled access, so the manager can demonstrate, if checked, both the completeness of the data required by law and a proportionate approach to processing.

Why dedicated software reduces errors

Keeping the register on a spreadsheet or on paper forms separate from accounting exposes a building to a real risk: the same person appears with different data in the register, in the expense allocation plan and in the list of certified mail recipients, and the three versions drift apart over time until the first dispute exposes the mismatch. Software that links personal records to real estate units, ownership shares and communications avoids this duplication: a data point is updated once and the change propagates everywhere that co owner appears.

In AmministraPro the condominium register is a dedicated section connected directly to real estate units, ownership shares and communication history: when an owner's name or a cadastral detail changes, the update is immediate and consistent across meeting notices, expense allocations and mailings, with no need to touch several separate files.
