Does an Owner field exist on a detail object in a master-detail relationship?

1. Yes, it does

2. No, it does not

3. Only if it's explicitly defined

4. It depends on the sharing settings

The correct answer is: No, it does not

In a master-detail relationship in Salesforce, the detail record does not have its own owner field. Ownership is managed by the parent (master) record; when a detail record is created, it automatically inherits the ownership from the associated master record. This design facilitates a tightly coupled relationship between master and detail records, where the detail's access and sharing settings align with those of the master. In contrast, the master object holds the Owner field, allowing its records to be assigned to specific users, which governs the sharing model within the organization. This design promotes data integrity and streamlined permissions by ensuring that detail records are automatically linked to the lifecycle of their master records. Thus, when you are working within a master-detail scenario, it is crucial to remember that detail records exist under the ownership of their master and therefore do not possess an Owner field independently.
