Legal Definition
A company subsidiary is a separate legal entity that is owned or controlled by another company, often the parent company, which can be an affiliate or division of the larger organization. In a corporate structure, this term denotes a distinct legal unit operating under the umbrella of a larger corporation.
Plain-English Translation
Imagine a big company that has different parts. A subsidiary is like one of those smaller parts—a separate business owned by the main company. It means the parent company owns and controls another company, which is a part of its overall structure.
