How to cancel the declaration of apartment

A "declaration of apartment" is a legal document that establishes ownership and details about an apartment, including its dimensions, location, and common areas. It's often called a Deed of Declaration or a Deed of Trust.

If the builder is reported to have died, who had executed the deed of declaration?

Whether the construction of entire  apartment and the  complex has been completed and handed over to the apartment owners association?
