Trustee Stephen Meininger said in a final report filed in bankruptcy court last month that $22,000 should be paid to attorney Allan Watkins.
In an interview with The Associated Press on Monday, Meininger said Watkins spent more money than he is receiving investigating false claims.
Meininger says bankruptcy law provides that the trustee and those working for the trustee get paid first.
Watkins says the $25,000 was loaned to Anthony by a friend so Anthony could buy back the rights to her life story. Meininger says those rights went to the trustee fund once Anthony filed for bankruptcy.
Anthony was acquitted in 2011 of murdering her 2-year-old daughter.
