Ric Flair claims he was supposed to pocket $25,000 for the ESPN "30 for 30" special on his life -- but his manager stole the money ... and now he's out for legal justice.
Nature Boy is suing Legacy Talent and Entertainment -- the management company he used from 2009 until October 2017.
Flair says he had a feeling something fishy was going down behind the scenes so he hired a lawyer to investigate his finances ... and realized he was missing huge amounts of cash.
