Quorum and majorities at the owners' meeting in Mexico City

Short answer

On first call an attendance of 75 per cent of the owners is required. On second call the quorum is a simple majority of all owners. On third call the assembly is legally installed with the owners who attend, and resolutions are taken by a majority of those present. In general, resolutions are taken by simple majority of the votes, unless the law, the deed or the internal rules require a special majority.

What this means in practice

Each owner has votes equal to the percentage of indiviso that their unit represents in the value of the condominium. Owners in arrears do not count for the quorum. Representation by simple power of attorney is possible only if the internal rules allow it; one person cannot represent more than two owners, and the administrator cannot represent an owner.

General information, not legal advice. Check with a lawyer in Mexico City before relying on it, and read your building's own documents: they can change how a rule applies.

Where Unitify fits

Unitify records how each owner votes and shows participation (units voted out of the units invited) and the result. Whether a meeting has a quorum and a decision passes is decided by the law above and your own rules; the record helps you check it.
