The six adult children of late soul legend James Brown have lodged a legal challenge in a South Carolina court to how his estate is being handled.
Brown is cited as an influence by many top stars
They have filed an emergency petition seeking the removal of its trustees, claiming assets are in danger.
The trust manages Brown's estate and music rights. His personal items were dealt with separately in his will.
The trustees have denied any mismanagement since Brown died from pneumonia on 25 December.
Trustee Buddy Dallas, who was Brown's lawyer, said everything in the trust was handled "appropriately and properly".
A court hearing has been scheduled for 1 February.
Fans and celebrities lined up to pay tributes to the soul legend, who was best known for hits such as I Got You (I Feel Good) and Living in America.
But since his death a number of legal wrangles have sprung up.
The late singer's partner, Tomi Rae Hynie, and Brown's family have clashed over the will, which did not include her or the five-year-old child she had with him.
