MEMORANDUM AND ORDER On March 2, 2020, pro se plaintiff Christopher McKie filed this civil action against an estate and its two co-administrators, who are relatives of the decedent. Presently before the court is defendants’ motion to dismiss the complaint pursuant to Federal Rule of Civil Procedure 12(b)(6). For the reasons set forth below, the complaint is dismissed for lack of subject matter jurisdiction, pursuant to Federal Rule of Civil Procedure 12(h)(3) (“Rule 12(h)(3)”), and defendant’s motion is terminated as moot. BACKGROUND The following factual allegations are taken from the complaint and are assumed to be true for purposes of this Memorandum and Order. Plaintiff was the companion, care-giver, and assistant to Ms. Dickinson during the final years of her life and handled her personal and financial affairs. Ms. Dickinson had intended to name him as the beneficiary of her estate and informally created documents to that effect, but died intestate. Ms. Dickinson had an unpleasant relationship with her aunt, defendant Peggy Kornegay, who, along with her two sons, were the only living relatives known to plaintiff. After the funeral, for which plaintiff paid the costs, Ms. Dickinson’s brother, Defendant Charles Kornegay, appeared. Peggy and Charles Kornegay were appointed co-administrators of the decedent’s estate. The individual defendants subsequently destroyed the documents allegedly describing the decedent’s intentions to provide for plaintiff, and demonstrating plaintiff’s close relationship with the decedent. Further, the individual defendants allegedly used their position as co-administrators to seize all of the decedent’s assets, including a pick-up truck that had been purchased using plaintiff’s funds, but was in the decedent’s name. Plaintiff was not compensated for his work in caring for the decedent and managing her financial, medical and real estate affairs. Plaintiff asserts that this court has jurisdiction pursuant to 28 U.S.C. §§1331, 1335, and 1343(a)(1). Plaintiff’s complaint does not, however, assert any federal question, interpleader, or civil rights violations. Instead, plaintiff asserts only state law causes of action, including fraud, contract, and quantum meruit. Plaintiff also asserts that this court has diversity jurisdiction pursuant to 28 U.S.C. §1332(a)(1), but fails to allege the domicile of any party; instead, he states that plaintiff and defendant Peggy Kornegay are both residents of New York State. Plaintiff requests monetary damages from the individual defendants and from the estate of Doris Dickinson. (Compl.
