You're asking for details from ages ago. Not many sources still online and not easy to find.

"[SCO] has cut a deal with the law firm Boise Schiller and Flexner to cap its legal fees at a maximum of $31 million in return for the legal lads getting a bigger cut of the spoils should they win." https://www.networkworld.com/article/2325008/sco-s-case-does...

"In return for agreeing to cap its legal fees, Boise, Schiller & Flexner is now entitled to a larger percentage of any legal settlement that may be reached in SCO's lawsuit over IBM's contributions to the Linux operating system. The law firm will now be paid between 20% and 30% of any settlement, depending on the amount awarded, McBride said." https://www.computerworld.com/article/2566954/sco-caps-legal...

There's actually a well preserved blog from the time that covers the entirety of that era, http://www.groklaw.net/
