Quick Summary

The term "negotiorum gestio" originates from Roman law and refers to a situation where one person voluntarily manages another's affairs without their authority, but for their benefit. This act creates an obligation for the manager to claim reimbursement and indemnity from the person whose affairs were managed. It is a form of quasi-contract, meaning it resembles a contract but arises without an explicit agreement. This concept is distinct from "gestio pro haerede," which pertains to conduct as an heir that makes one liable for an ancestor's debts.12
