Patrick Ligner is a lawyer and co-founder of the Goldberg, Ligner and Shyster law firm, alongside Tom Goldberg and Dick Shyster. He is not seen during Grand Theft Auto IV but his photo can be found on the official GTA IV website.
According to the law firm's website, Ligner is dedicated to battering society. He became well-known after bankrupting the law school he recently graduated from with only one lawsuit. He went on constructing cases against his undergraduate college, high school, and elementary school. He wrote the book "Five Easy Ways to Spot a Lawsuit: Rudimentary Case Construction," which became a Liberty Tree bestseller and Weazel News Book of the Week.
He is expected to be taking the remainder of cases that Dick Shyster takes over from Tom Goldberg after Goldberg's death, as it's said that Shyster will be taking most of Goldberg's cases.
- In the mission Wrong is Right, an email from a "Larry Ligner" sent from firstname.lastname@example.org can be found on Oleg Minkov's computer. This would imply that Larry was Patrick's original name.
- His character model (which is also used for Mr. Parker) is also the model used for a generic Italian mobster.
