According to documents filed by Lockwood, he believes Presley failed to produce documents during a recent deposition, including tax returns, income documents, bank statements, property records, expense records, outstanding debts and credit card statements.
Lockwood also claims Presley makes more than she admits from The Promenade Trust -- which was created from an agreement between Lisa Marie and Priscilla -- and gets paid from the uses of image, likeness and trademark of Elvis.
He believes Presley received more than $70 million during their marriage, and wants it revealed to help determine support.
Presley and Lockwood wed in 2006 and have been locked in a contentious divorce since 2016. They have twin 9-year-old daughters.
He believes the documents are needed to help determine if a post-nuptial agreement signed by the parties is valid and enforceable, and also figure out spousal support and division of assets.
