Citizenship for Estate Representative
Dominic Drake died domiciled in Texas. His executor, a New York resident, sued a Delaware corporation in federal court asserting diversity jurisdiction. The court treated the executor as a Texas citizen solely because that was the state of the de cujus.
Executor Promise to Creditor
After Diane Dawson's death, her executor orally promised a supplier that the estate would pay an existing debt Dawson had incurred. The supplier later sued on the oral promise. The court held the promise unenforceable because it was an undertaking by the executor to answer for a duty of the de cujus.

Duty Owed to Decedent's Estate

Common questions
Frequently Asked
4
How does the term de cujus affect diversity jurisdiction when an estate sues?+
The legal representative of the estate is deemed a citizen only of the same state as the de cujus. This rule prevents the representative's own citizenship from creating or destroying diversity.
When must a promise by an executor be in writing?+
A promise by an executor to answer for a duty of the de cujus falls within the statute of frauds. The promise is unenforceable unless evidenced by a signed writing.
What happens to a pending tort action when the plaintiff dies?+
If the claim survives, the court may substitute the proper party. The action continues in the name of the estate of the de cujus rather than abating.
Does the term de cujus appear in intestate succession analysis?+
Yes. Courts use the term to identify the decedent whose property passes by intestacy to heirs determined under the probate code.
