Selena Quintanilla-Pérez's siblings are engaged in a legal dispute over the late singer's estate, more than three decades after her murder. Selena's brother, A.B. Quintanilla, has filed a lawsuit against his sister, Suzette Quintanilla Arriaga, and her company Q Productions, seeking more than $1 million for what he asserts is his rightful share of Selena's estate.

The lawsuit alleges that Suzette and Q Productions have failed to pay A.B. his complete share of profits derived from Selena's various entertainment properties. Q Productions is responsible for managing Selena's entertainment affairs, intellectual property rights, commercial ventures, and overall legacy.

Prior to the lawsuit's filing, both Suzette and their mother, Marcella, released a joint statement denying any misconduct. "There was no theft by Suzette. Suzette has not stolen, misappropriated, or improperly taken money or property belonging to A.B., Abraham, Marcella, Chris, Selena's estate, or any family-owned or jointly owned business," the statement read.

Chris Perez, who was married to Selena, stated on Facebook that he would not be involved in the legal proceedings in any official capacity. Selena, known for hits like "Como la flor" and "Dreaming Of You," was murdered on March 31, 1995, in Corpus Christi, Texas, by Yolanda Saldívar, the president of her fan club. Saldívar was convicted of murder and sentenced to life in prison. She was denied parole last year and will not be eligible again until March 2030.

Selena's family and Chris Perez had previously expressed gratitude for the parole board's decision, stating that "justice continues to stand for the beautiful life that was taken from us and from millions of fans around the world far too soon."

Selena was a highly popular Mexican-American singer before her death, and her influence in Latin and Tejano music has grown posthumously. Her posthumous album, "Dreaming Of You," released in July 1995, became the first album by a Latin artist to top the Billboard 200 chart. The 1997 biopic about her life and death, also titled "Selena," further solidified her music's cultural impact and marked Jennifer Lopez's breakthrough performance in the lead role.
