How to calculate the majority for a resolution
Every valid resolution passed by an Italian condominium meeting depends on two numbers that must align: how many owners voted in favor and how many thousandths of ownership share, millesimi, those owners represent. Article 1136 of the Italian Civil Code sets different quorum thresholds depending on the subject matter, from appointing the property manager to costly building improvements, and getting the calculation wrong exposes the resolution to challenge within thirty days. This guide explains how to read the quorum table, how to calculate head count and ownership shares from the meeting minutes, the most common errors seen in real meetings, and how automated calculation tools, like the one built into AmministraPro, reduce the manager's margin for error.
Head count and ownership shares: two tallies that must both add up
In an Italian condominium meeting, a majority is never measured by a single criterion. The Civil Code almost always requires a double quorum: the number of owners present or represented by proxy, the heads, and the value in thousandths of ownership, millesimi, that those owners represent out of the building's one thousand total shares. An owner with a small unit and an owner with a penthouse count equally as one head each, but they carry very different weight in the millesimi tally.
This dual system exists to balance two logics of representation: a democratic one, one head one vote, and a proprietary one, which gives more weight to owners holding a larger share of the building. A resolution passes only when both quorums required by law for that specific subject are met at the same time, meeting only one of the two is not enough.
The quorums under Article 1136 of the Civil Code
Article 1136 distinguishes between the constitutive quorum, the threshold needed for the meeting to be validly convened, and the deliberative quorum, the threshold needed for a proposal to be approved. On first call, the law generally requires a majority of attendees representing at least two thirds of the building's value for the meeting to be validly constituted; on second call, usually scheduled a few days later, quorums drop considerably.
- Ordinary administration and appointment of the property manager: a majority of attendees representing at least half the building's value
- Significant extraordinary maintenance works and building improvements: a qualified majority with a higher millesimi threshold
- Costly or non essential improvements: a reinforced majority protecting owners opposed to the expense
- Amendments to the condominium bylaws: a majority of attendees holding at least half the millesimi
- Replenishing the fund for urgent works or works already provided for by the bylaws: eased quorums compared with ordinary improvements
How the calculation works in practice: a worked example
Consider a building with ten units and a millesimal table assigning different weights to each apartment, totaling one thousand millesimi. Seven owners attend the meeting, representing six hundred millesimi. For an ordinary administration resolution requiring a majority of attendees and at least five hundred millesimi, the manager must verify two separate things: that the favorable votes exceed half the heads present in the room, so at least four out of seven, and that the millesimi held by those who voted in favor exceed the five hundred required by law, calculated on the building's total of one thousand, not only on those present.
The most common mistake is calculating the percentage on the millesimi present at the meeting instead of on the building's full one thousand: this changes the outcome significantly and can lead to declaring a resolution approved when it has not actually reached the legal quorum, leaving it open to challenge.
Automated calculation in AmministraPro
Keeping the meeting minutes, the millesimal table, and the legal quorums aligned by hand, especially in meetings with many proxies, increases the risk of error at the exact moment a resolution becomes binding on everyone. AmministraPro links the condominium's millesimal table directly to the meetings module: as the manager records attendees and votes, the software automatically calculates both the head count and the millesimi against the building's total and flags whether the quorum required by Article 1136 for that specific matter has actually been reached, reducing the risk of minutes that can later be challenged.
Frequently asked questions
What happens if a resolution is approved without reaching the required quorum?
A resolution adopted without meeting the quorum required by Article 1136 is defective and can be challenged in court by owners who were absent, dissenting, or abstained, within thirty days of receiving the minutes, a term that runs from the date of the meeting for those who attended. If the challenge succeeds, the resolution loses effect and the meeting may need to be reconvened to vote again on the same matter with the correct quorum.
Why are there two separate quorums, one by head count and one by ownership share?
The double quorum balances two forms of representation set out in the Civil Code: the head count quorum protects owners with smaller shares from decisions imposed by a few large owners, while the millesimi quorum recognizes that whoever holds a larger portion of the building also bears a larger share of the common expenses and should have proportionate weight in decisions affecting them.
Do proxies count toward both the head count and the ownership share quorum?
Yes, an owner attending by proxy votes on behalf of the person who granted it, and that vote is counted as one head present together with the millesimi belonging to the person who granted the proxy, not the millesimi of the proxy holder. This is why the minutes must record precisely who is representing whom, otherwise the quorum calculation is distorted.
Are quorums always lower on second call?
Generally yes, Article 1136 provides for reduced quorums on second call precisely to prevent the condominium from being stuck when first call fails to attract enough attendees, but some particularly sensitive matters, such as certain costly improvements, keep higher thresholds even on second call, so the specific majority required for the item on the agenda must always be checked.
Can software really prevent errors in calculating majorities?
A tool that links the condominium's official millesimal table to the record of attendees and votes, like AmministraPro's meetings module, removes the risk of manual arithmetic mistakes and automatically recalculates head count and millesimi against the building's total with every vote logged, though it remains the manager's responsibility to verify which specific quorum applies based on the subject matter being decided.
