The LIV Golf Team Championship will be contested from October 27-30 at Trump National Doral outside Miami. Saudi Arabia's Public Investment Fund finances the upstart Tour that's peeled away dozens of players from the PGA Tour and DP World Tour.

ESPN has reported the record prizemoney and, along with golf.com, has also revealed previously unknown details about the team championship's format, which could feature a closest-to-the-pin contest.

LIV Golf's rules and regulations were released by a US District Court in California amid the group's antitrust lawsuit against the PGA Tour. The Team Championship's description was initially redacted before being released on Tuesday.

"The Team Series Championship will be played over four days as a match-play head-to-head knock-out playoff, with the winning Team crowned as the 'Team Series Champion’," one passage says.

"Each team will be ranked and seeded one (1) through twelve (12) for competition in the Team Series Championship based on a shootout undertaken immediately following the Player Draft preceding the Team Series Championship, with each Team Captain having one (1) shot to hit toward a target in a 'nearest the pin'-style shootout."

The winning four-man team would win $US16 million ($A23.7m), or $US4 million ($A5.94m) per player. The second-place team would win $US10 million, with $US8 million going to third, $US4 million to fourth, $US2 million for Nos.5-8 and $US1 million for ninth through 12th, meaning even a golfer on the last-place team would be guaranteed to take home $US250,000.

According to ESPN, a LIV spokesperson said details were not yet finalised and the format would be announced at a later date.
