At this time, HubSpot does not support restricting visibility or access to individual forms based on specific users or teams within your account. User permissions for forms are set at the tool level—meaning that any user with access to the Forms tool will be able to see and manage all forms in your account. Unfortunately, partitioning by teams or limiting rights to only certain forms is not currently available.
Limiting access to forms by user or team is important for our business needs.
