Aaliyah’s family is locked in an increasingly bitter legal battle that has now brought a stunning allegation about the singer’s 2001 death back into the spotlight.

Barry Hankerson, Aaliyah’s uncle and longtime manager, is accusing his own son — Aaliyah’s cousin Jomo Hankerson — of failing to properly handle travel arrangements surrounding the Bahamas trip that ended with the singer’s fatal plane crash.

The allegation surfaced as father and son battle in court over money and rights connected to music from Aaliyah and several other major artists.

Jomo has denied wrongdoing.

The dispute has also escalated financially, with Jomo reportedly indicating that he would settle his claims against his father for $20 million.

According to court documents obtained by TMZ, Barry claims Jomo was paid to accompany Aaliyah and coordinate transportation for the singer’s music video shoot in the Bahamas in August 2001.

Aaliyah had traveled there to film the video for “Rock the Boat.”

Barry alleges his son “failed in his responsibility” to properly handle those arrangements.

He further claims Aaliyah ultimately boarded the private aircraft that crashed shortly after takeoff and that the tragedy “may have been avoided” if Jomo had completed the travel coordination he was allegedly paid to handle.

The allegation is Barry’s claim in an ongoing lawsuit and has not been established as fact in court.

Barry also reportedly said his relationship with his son was never the same after Aaliyah’s death.

Aaliyah was just 22 when she died on August 25, 2001.

The singer and members of her team had finished filming “Rock the Boat” in the Bahamas and boarded a small aircraft departing Marsh Harbour Airport.

The plane crashed shortly after takeoff, killing Aaliyah and the eight other people aboard.

Subsequent investigations raised serious concerns surrounding the flight, including the aircraft’s weight and the qualifications and condition of its pilot.

More than 25 years later, the circumstances surrounding that trip have now become part of an unrelated family dispute over music assets.

The family conflict began with Jomo suing his father and Blackground Records over money he claims he is owed under a previous settlement.

The disputed assets reportedly include recording masters and publishing copyrights connected to Aaliyah, Toni Braxton, DMX and Timbaland.

Jomo alleges that he is entitled to 12 percent of money Barry received from those music assets.

He has accused his father and Blackground Records of hiding revenue and creating unrelated expenses in an effort to reduce what Jomo would ultimately receive.

Barry has denied those allegations and argues that the settlement Jomo relies on is invalid because it was allegedly obtained through fraud.

The financial stakes have since grown considerably.

In correspondence between attorneys obtained by TMZ, Jomo’s representatives reportedly said he would settle the ongoing dispute for $20 million.

According to the report, Jomo's position is that if Barry believes the eight-figure demand is excessive, he should turn over financial records showing exactly how much revenue the disputed music catalog has generated.

Earlier filings had Jomo seeking more than $1.2 million in damages, but the latest settlement demand suggests the dispute over the value of the music assets could be substantially larger.

The accusations extend beyond money and Aaliyah’s final trip.

Barry has also alleged that Jomo previously threatened to release unreleased Aaliyah recordings unless his financial demands were met.

Jomo has denied wrongdoing.

Neither side’s claims have been resolved by the court, and the litigation remains ongoing.

The increasingly personal dispute has now turned what began as a fight over royalties and ownership into a painful public family feud involving one of the darkest moments in music history.

More than two decades after Aaliyah’s death, her legacy and catalog remain enormously valuable.
