What other functions does an administrator of a community have apart from those stipulated in the Shared Property Law (la Ley de Propiedad Horizontal). Can the Administrator be held responsible for their actions?

Lawyer’s answer:

The Shared Property Law (la Ley de Propiedad Horizontal) gives the Administrator certain powers to act on behalf of a Community of Property Owners. But any further duties or funcitions undertaken by the property administrator must have the mandate of the property owners.

Property administrators in Spain are certainly not allowed to take unilateral decisions, and under article 1726 of the Civil Code they are responsible for their actions.
