Bedelia Hargrove filed legal papers earlier this month (Feb16), accusing Brown's maternal grandmother Cissy Houston and aunt Pat Houston of failing to distribute funds to allow her to operate the estate of Whitney Houston and Bobby Brown's daughter.

According to, the trust, which was established before Brown passed away last year (Jul15), is used to pay the late 22-year-old's estate expenses. However, the Houstons, who are co-trustees, have reportedly refused to pay the bills unless they deem them "reasonable", and Hargrove insists none of the expenses have been covered. She is seeking unspecified damages and lawyers' fees.

"Respondents are impairing and impeding the proper administration of the estate," the suit filed in Fulton County Superior Court in Georgia reads. "To date, the respondents have failed and refused to pay any expenses of administration of the estate after proper and repeated demands from the petitioner."

Bobbi Kristina passed away in July (15), six months after she was found face down and unresponsive in a bathtub at the Georgia home she shared with boyfriend Nick Gordon. She was taken to a nearby hospital, where doctors placed her in a medically induced coma, from which she never woke.

Hargrove filed a $10 million (£6.9 million) wrongful death lawsuit against Gordon following Brown's passing. In the legal papers, she accused him of giving his girlfriend a "toxic cocktail", which rendered her unconscious on the night of 31 January (15). Gordon maintains he is innocent of all Hargrove's accusations.
