Common Examples

Guild Members Destroy Diversity
The National Screen Actors Guild, whose thousands of performer members include many domiciled in State X, sues StreamWave Inc., a State X corporation, in federal court for unpaid residuals. Because the Guild takes on the citizenship of every member, it shares State X citizenship with the defendant and the court lacks diversity jurisdiction.
LLC Partners Overlap With Defendant
Arkview Apartments LLP, whose partners include individuals domiciled in State C, sues MetroManage Corp., a corporation with its principal place of business in State C. The LLP takes on the citizenship of each partner, shares State C citizenship with the defendant, and the federal court therefore lacks diversity jurisdiction.

Indian Association Citizenship Challenged
Affiliated Ute Citizens, an unincorporated association of tribal members, brings suit in federal court against a corporate defendant incorporated in State Y. Several members of the association are domiciled in State Y, so the association shares citizenship with the defendant and diversity jurisdiction fails.
Affiliated Ute Citizens of Utah v. United States406 U.S. 128, 153-154 (1972)
Union Members Share State Citizenship
Textile Workers Union, an unincorporated association, sues a corporate employer in federal court. Multiple union members reside in the same state as the employer, so the union takes on that state citizenship and complete diversity is absent.
Textile Workers Union of Am. v. Lincoln Mills of Ala.353 U.S. 448 (1957)
Cooperative Members Overlap With Plaintiff
Prime Land, a farming cooperative organized as a partnership, is sued by Valley Harvest, a corporation domiciled in Iowa. Several cooperative members reside in Iowa, so the partnership takes on Iowa citizenship and the federal court lacks diversity jurisdiction over the action.
Van Dusen v. Barrack376 U.S. 612 (1964)
Welfare Organization Members Defeat Diversity
Eastern Kentucky Welfare Rights Organization, an unincorporated association, sues a hospital corporation in federal court. Because some association members share citizenship with the defendant hospital, the organization takes on that citizenship and diversity jurisdiction does not exist.
Simon v. Eastern Kentucky Welfare Rights Organization426 U.S. 26, 40–41 (1976)
Common questions
Frequently Asked
4
How is the citizenship of an unincorporated association determined for diversity jurisdiction?+
Federal courts treat an unincorporated association as a citizen of every state in which any of its members is domiciled. The association therefore shares citizenship with any defendant who is a citizen of a state where even one member resides, destroying complete diversity.
Supporting sources
Are LLCs treated like corporations or like unincorporated associations for diversity purposes?+
LLCs are treated as unincorporated associations. Their citizenship is determined by the citizenship of each member rather than by any state of formation or principal place of business.
Supporting sources
Does the citizenship of only managing members control the diversity analysis for an unincorporated association?+
No. Every member’s citizenship counts, not merely the citizenship of those who manage or control the entity. Overlap between any member and an opposing party defeats complete diversity.
Supporting sources
What happens when members of two LLCs overlap across multiple tiers of ownership?+
Citizenship is traced through every tier. Shared members at any level cause both LLCs to take on the same state citizenship, destroying complete diversity even if the entities operate separately.
