• Twitter is demanding Elon Musk's texts be searched and relevant ones be handed over.

• Both sides are seeking more information as Twitter's lawsuit to force Musk's acquisition evolves.

• A judge overseeing the case just told Twitter to hand over documents from a former executive.

Twitter is trying to get its hands on Elon Musk's text messages amid its $44 billion legal battle with the billionaire, new court documents show.

The company on Monday said it wants a search conducted of all of Musk's text messages during "the relevant period" for "material" related to its lawsuit.

Twitter sued Musk last month after the billionaire attempted to back out of his April deal to acquire the company for $44 billion. Twitter's demand for Musk's texts came in a proposed order filed Monday which has yet to be signed off on by Judge Kathleen St. Jude McCormick who is overseeing the case.

The proposed order does not specify when exactly the "relevant period" is and many of the documents in the case so far have been filed confidentially, meaning they are not immediately made available on the court's docket. However, the period of Musk's texts sought by Twitter likely cover the time between when Musk first agreed to purchase the company on April 25 and when he attempted to back out of the deal via a letter from his lawyers on July 8.

A spokesperson for Twitter declined to comment. Representatives of Musk did not immediately respond to a request for comment ahead of publication.

Musk and Twitter have been going back and forth for weeks on who has to produce what and how much information may be relevant to the lawsuit. On Tuesday, Musk gained a rare win after the judge ordered the social media company to hand over documents related Musk's quest for information on spam accounts from an executive who was fired earlier this year. Musk maintains that Twitter misled him on the level of its problem with "bots," also known as spam accounts, often meaning numerous accounts operated by a single person or entity for the purpose of pushing products or scams.
