A.B. Quintanilla Claims Lawsuit In Family Dispute

Suzette Quintanilla Arriaga and their mother, Marcella Quintanilla, publicly stated they had not been served with any lawsuit and could not locate a public filing, asking: 'What lawsuit? Where was it filed? What is the case number?'
A.B. Quintanilla claimed documents were sent to Suzette via certified mail and email, and his posts included a letter from Manatt, Phelps & Phillips addressed to Michael A. Trauben, Esq.
Billboard noted that A.B.’s second post appeared to show a redacted screenshot of a cease-and-desist letter—distinct from a lawsuit—citing allegations about Suzette’s fiduciary duties.
Public-record searches reported by Billboard found no publicly available court filings in major jurisdictions (Los Angeles, New York, Delaware, federal court, or Nueces County probate) to corroborate the lawsuit or associated figures.
Abraham Quintanilla Jr. died in December 2025 at age 86, a detail referenced in reporting about the family dispute and the estate.
A.B. Quintanilla III, brother of late Tejana singer Selena, publicly claimed there is a lawsuit involving his sister Suzette Quintanilla Arriaga and matters tied to their father Abraham Quintanilla Jr., who died in December 2025 at age 86. Fresno Bee reported that A.B. said documents were sent via certified mail and email, though Suzette and their mother Marcella say they have not been served and cannot find any public court filing.
The dispute centers on alleged fiduciary duty violations and marks the latest tension in the Quintanilla family. Billboard found no public court records in Los Angeles, New York, Delaware, federal court, or Texas probate courts to back up A.B.'s claims or unverified figures circulating online like a $30 million stake sale.
A.B. posted what he said were legal documents on social media, including a letter from law firm Manatt, Phelps & Phillips. Billboard noted his posts appeared to show a redacted cease-and-desist letter—not an actual lawsuit filing. The letter cited allegations about Suzette's fiduciary duties to estate beneficiaries.
A.B. said he would reveal more details later but did not immediately provide the lawsuit case number or filing location. He stated the dispute stems from years of family tensions that escalated recently.
Suzette Quintanilla Arriaga and Marcella Quintanilla pushed back hard. Kansas.com reported they publicly stated they had not been served with any lawsuit and questioned: 'What lawsuit? Where was it filed? What is the case number?' They said they could not locate any public filing.
Their denial contradicts A.B.'s claims that he sent certified mail and email notices. The family disagreement over whether documents were actually delivered has become part of the broader public fight.
Billboard searched public records across major courts and found nothing. No filings appeared in Los Angeles, New York, Delaware, federal court, or Nueces County probate court in Texas. This absence raises questions about whether a lawsuit actually exists or if it remains private and unfiled.
Unverified figures have circulated online—including claims of a $30 million stake sale and roughly $48 million in other sums. Complex reported these numbers lack confirmation from the family or any public documents. The lack of verifiable facts has deepened confusion about the dispute's actual scope.
A.B. framed this dispute as rooted in years of accumulated family disagreements. Sun Herald reported his claim that tensions finally reached a breaking point, though he has not detailed the specific grievances publicly. The timing coincides with their father's death just months earlier.
The fight has drawn fresh attention to Selena's legacy and the Quintanilla family's business interests. The public airing of private disputes marks a rare crack in the family's carefully managed public image surrounding the late singer's estate and brand.
