California Codes, Code of Civil Procedure - CCP, Part 2 — Of Civil Actions, Title 11 — Contribution Among Joint Judgment Debtors, Chapter 1 — Releases From and Contribution Among Joint Tortfeasors, Section 876
(a) The pro rata share of each tortfeasor judgment debtor shall be determined by dividing the entire judgment equally among all of them.
(b) Where one or more persons are held liable solely for the tort of one of them or of another, as in the case of the liability of a master for the tort of his servant, they shall contribute a single pro rata share, as to which there may be indemnity between them.
Notes
Sets each tortfeasor judgment debtor’s pro rata share by dividing the entire judgment equally among all such debtors. When multiple persons are liable solely for one person’s tort, such as master-and-servant liability, requires them to contribute one combined pro rata share, while allowing indemnity among them.
