An online feud surfaced between members of the late Tejano singer Selena Quintanilla's family over claims of a lawsuit.
The exchange started Sept. 1 when A.B. Quintanilla III posted a statement on his Instagram claiming that he had filed a lawsuit related to his sister, Suzette Quintanilla-Arriaga, as well as "to facts and circumstances related to my father, Abraham Quintanilla."
The brother of Selena said the lawsuit "began a few months ago" but that it stemmed from years of "accumulated situations, decisions and circumstances" involving his family.
He went on to say he would not be granting interviews or provide details of the lawsuit at this time, but will speak "when the right time comes."

The next day, on Selena's Instagram, Quintanilla-Arriaga and the siblings' mother, Marcella Quintanilla, released a statement claiming A.B. Quintanilla III's statement contains "serious and false insinuations."
The statement said Quintanilla-Arriaga was never served a lawsuit, a court-file complaint, summons, petition or other legal pleading.
Texas court records did not show a lawsuit under A.B. Quintanilla III's name as of Sept. 4.
The post on Selena's Instagram said he claimed Quintanilla-Arriaga had stolen, misappropriated or improperly taken money or property belonging to the family or Selena's estate. The mother and daughter asked him to state the claims rather than "leaving the public to speculate."
The same day, A.B. Quintanilla III responded to his family with another Instagram post claiming his sister and her lawyers were notified of a lawsuit with corresponding documents via certified mail and email.
The post includes a photo of a pre-suit legal demand letter, not a filed lawsuit. It shows the letter was sent Aug. 26, 2025, from the Manatt law firm to the law office of Michael A. Trauben. Both firms are based in California.
Most of the letter is redacted, but it references a July 23, 2025, email that "lays bare Suzette Quintanilla's utter disregard for her fiduciary duties to the Estate's beneficiaries."
In his post, A.B. Quintanilla III said his sister was notified of the "lawsuit" related to her fiduciary duties. He claimed she responded but did not provide contracts, documentation and financial information that was requested.
He said his lawyer will "speak out and many things will be made clear" on Sept. 4.
Trauben and the Manatt firm did not immediately respond to requests for comment.
The tiff among the family members comes nine months after the death of Abraham Quintanilla on Dec. 13, 2026. The news was first shared by A.B. Quintanilla III in an Instagram post.
