A.B. Quintanilla III has filed a lawsuit against his sister, Suzette Quintanilla-Arriaga, and corporate entities including Q Productions, alleging unpaid profits and a lack of financial accounting related to the estate and entertainment properties of his late sister, Selena Quintanilla-Pérez. The lawsuit, filed on September 10, 2026, in Nueces County, Texas, claims A.B. was entitled to 25% of net profits from Selena's entertainment properties since 2016 and seeks over $1 million in monetary relief. This legal dispute escalates a family disagreement that became public earlier this month.
