A more thorough explanation:

Corporate domicile refers to the legal home of a corporation, usually its state of incorporation or the state where it conducts most of its business. For example, if a corporation is incorporated in Delaware but has its headquarters in California, its corporate domicile would be California.

For legal purposes, a corporation is considered a citizen of both its state of incorporation and the state where it maintains its principal place of business. This is important for determining whether diversity jurisdiction exists in federal court.

Example: XYZ Corporation is incorporated in Nevada but has its main office in New York. Its corporate domicile would be New York, and it would be considered a citizen of both Nevada and New York for legal purposes.
