The Quintanilla family is taking their personal disputes to the public.
On Tuesday, A.B. Quintanilla III — brother of the late Tejana singer Selena Quintanilla — uploaded a statement to Instagram claiming that there is a lawsuit involving Suzette Quintanilla Arriaga, as well as “facts and circumstances” related to their father, Abraham Quintanilla Jr.
According to the Latin Grammy-winning producer and songwriter, the lawsuit began a “few months ago,” but he shared that the circumstances surrounding the case have been simmering for years.
“What led me to this point did not start a few months ago. It comes from years,” stated A.B. “Years of accumulated situations, decisions and circumstances that for a long time I chose to keep silent out of respect, out of loyalty, and above all, because it involved my own family.”
While no clear wrongdoing was presented in his statement, the Kumbia Kings musician shared that, when the time is right, he will disclose his side of the story. “I was never the type to wait for the paycheck from someone else’s hard work to come to my door,” he added.
After his post, Suzette and Marcella Quintanilla, their mother, published a joint statement Wednesday morning on the official Selena Instagram account, claiming that the parties involved were not served a lawsuit, nor have they been able to locate the alleged lawsuit in public records.
“[Suzette] has received no court-filed complaint, summons, petition, or other legal pleading concerning the allegations A.B. is describing,” read their statement. “So, we ask a simple question: What lawsuit? Where was it filed? What is the case number?”
In a subsequent Instagram post uploaded Wednesday by A.B., he alleged that Suzette and her lawyers were notified with the corresponding documents via mail and electronic mail; the carousel also contained a letter by Manatt, Phelps & Phillips addressed to Michael A. Trauben, Esq., of Sign, Sign & Trauben.
“She was notified of a lawsuit related to her fiduciary duties, that is, her legal obligations to act with loyalty, transparency and in the best interests of those she was responsible to,” read the statement uploaded by A.B. “She responded, but did not provide what was being requested: contracts, documentation and financial information.”
The Times attempted to locate the lawsuit in Nueces County, Texas, court — headquarters for Q-Productions, an entertainment company founded by Abraham, as well as the Selena Museum — but was unable to locate any case filings related to “Suzette Quintanilla” or “Suzette Arriaga.”
The only available case involving Suzette is a California lawsuit she filed against clothing company Shein in March over unauthorized merchandise that featured her late sister.
In their Sept. 2 Instagram post, Suzette and Marcella claimed that A.B.’s insinuations concerning Suzette, Abraham and the overall Quintanilla family were false.
The pair also addressed rumors that Suzette is selling personal belongings related to Selena, stating that “any potential sale of an ownership interest in a company is entirely separate and should not be mischaracterized as the sale of Selena’s personal items.”
“There was no theft by Suzette. Suzette has not stolen, misappropriated, or improperly taken money or property belonging to A.B., Abraham, Chris, Selena’s estate or any family-owned or jointly owned business,” read the statement. “If A.B. has evidence that Suzette stole or misappropriated anything, he should present it.”
This online dispute comes almost nine months after Abraham’s death on Dec. 13, 2025. The patriarch played a crucial role in the development of his daughter Selena’s career, establishing his family-led band Selena y Los Dinos in the 1980s as a way to meet financial needs. With A.B. on bass, Suzette on drums and Selena as the tender vocalist, the group would eventually sign their first recording contract with Freddie Records in 1984.
In 1995, after Selena’s tragic death at the hands of Yolanda Saldivar, the former president of her fan club, Abraham dedicated his life to safeguarding her legacy and overseeing primary control over her estate. This included managing the rights to her image, name and likeness — at times, to controversial ends.
“If he is alleging wrongdoing by Abraham, he should clearly state what he is alleging rather than leaving the public to speculate about a man that is no longer here to respond for himself,” stated Suzette and Marcella jointly.
A.B. and Suzette’s representatives did not immediately respond to a request for comment.
In his Wednesday Instagram statement, A.B affirmed that more information will be shared via his lawyer on Friday.
