Following the death of Zappa's mother, Gail, in October 2015, it was revealed that Ahmet and his sister Diva were given control of the Zappa Family Trust with shares of 30% each, while his siblings Moon and Dweezil were given smaller shares of 20% each. As beneficiaries only, Moon and Dweezil will not see any money from the trust until it is profitable—in 2016, it was "millions of dollars in debt"—and must seek permission from Ahmet, the trustee, to make money off of their father's music or merchandise bearing his name. The uneven divide of the trust has resulted in several conflicts between Zappa's children, including a feud between Dweezil and Ahmet over Dweezil's use of his father's music in live performances.
