CORPUS CHRISTI, Texas - Abraham "A.B." Quintanilla III, the brother of the late Tejano singer Selena Quintanilla, has filed a lawsuit against his sister, Suzette Quintanilla Arriaga, and Q Productions.

Court records show the lawsuit was filed in Nueces County on Sept. 10.

In the lawsuit, Abraham Quintanilla alleges that an agreement signed by members of Selena's family and her husband after her death entitles him to 25% of the net proceeds from certain entertainment properties connected to Selena.
