What document is signed by the property owner/developer to create a condominium?

The correct answer is the condominium declaration. This document is crucial in formally establishing a condominium. It outlines the essential features of the condominium, such as the legal description of the property, the individual units, common areas, and the respective rights of unit owners. Additionally, the declaration often includes provisions regarding governance, maintenance responsibilities, and the financial structure of the condominium association.

In essence, the condominium declaration serves as a foundational legal document that outlines how the condominium will operate. This is vital for both the developer and the future owners of the individual units, as it lays the groundwork for communal living and property management within the condominium framework.
