A U.S. federal court has mandated Craig Wright, a self-proclaimed bitcoin inventor, to submit his bitcoin addresses in an ongoing lawsuit filed against him by the estate of a previous business partner.

Ira Kleiman is suing Wright on behalf of the estate of his brother, the deceased Dave Kleiman. Wright is accused of scheming to “seize Dave’s bitcoins and his rights to certain intellectual property associated with the bitcoin technology.”

As a result, Kleiman is seeking to recover a portion of 1.1 million bitcoins (worth around $6.19 billion at the time of writing) mined by the two, or its “fair market value,” together with the payment for infringement of intellectual property.

On May 3, the southern district court of Florida issued an order, saying that Wright must submit a list of his bitcoin holdings as of Dec. 31, 2013. According to the document, Wright stressed however that he does not have a complete list of the bitcoin addresses.

Furthermore, Wright asserted that he moved the ownership of all his bitcoins to a blind trust in 2011.

The court has now requested Wright to also submit a sworn declaration naming the blind trust and its location by May 8. He must also provide a copy of any and all documents pertaining to the “formation, administration and operation” of the trust by May 9.

Furthermore, the court said:

“On or before May 15, 2019, at 5:00 p.m. Eastern time, Dr. Wright shall produce all transactional records of the blind trust, including but not limited to any records reflecting the transfer of bitcoin into the blind trust in or about 2011. The production shall be accompanied by a sworn declaration of authenticity.”

The court did not grant Wright’s attempt to dismiss the lawsuit in December 2018, stating that he “converted at least 300,000 bitcoins upon Dave’s death and transferred them to various international trusts.”
