Chargers owner and chairman Dean Spanos is being sued by his own family ... who accuse Uncle Dean of secretly diverting money meant for them after the team moved from San Diego.
The allegations are spelled out in a lawsuit filed Friday in San Joaquin County, California.
Dean's nephews, Dimitri and Lex Economou -- beneficiaries of the trust that owns a portion of the NFL team -- have accused Spanos of secretly changing the trust, screwing them out of boatloads of money in the process, according to the lawsuit.
