Which of the following is required for a stock cooperative's occupancy rights?

Occupancy rights in a stock cooperative are inherently tied to ownership of the stock shares that represent a share in the cooperative corporation. To occupy a unit within such a cooperative, a person must hold these shares as they grant the right to use the property. Therefore, the occupancy rights are directly linked to the transfer of stock shares, meaning that when shares are transferred, the accompanying rights to occupy the unit are transferred as well. This ensures that the new owner has the legal authority to reside in the property connected to the shares they receive.

Other options do not align with the regulations and operational norms of stock cooperatives – occupancy rights aren't typically transferable independently of the stock shares, they aren't limited exclusively to corporation employees, nor do they require verification by a real estate agent to validate their existence or enforceability. The direct connection between stock shares and occupancy is a fundamental principle governing stock cooperatives.
