Amazon CEO Jeff Bezos is seeking over $1.7 million from his girlfriend's brother, Michael Sanchez, to cover legal fees he incurred as a result of Sanchez's unsuccessful defamation lawsuit.

Bezos and his personal security chief, Gavin de Becker, filed a motion Friday with Los Angeles County Superior Court to compel Sanchez to reimburse them for $1,676,919.50 in attorney fees and $36,019.26 in other costs they racked up while defending a defamation suit from Sanchez last year.

"These fees and costs are reasonable and the amount of work performed was commensurate with that necessary to defend vigorously against Plaintiff's abusive and constantly shifting case. Consequently, Defendants' fee request should be granted in full," the motion reads, which is signed by Bezos' attorney, Edward Takashima.

Tom Warren, an attorney for Sanchez, told Insider in a statement that "Mr. Bezos' fee request is obscene, even grotesque, on many levels."
