Obligation to Pay for Non-Gratuitous Acts

In the context of quasi contracts, the obligation to pay for non-gratuitous acts means that if someone benefits from a service or benefit that wasn't given for free, they are expected to compensate the provider. This principle applies even when there’s no formal agreement. For example, if someone mistakenly receives and uses a service that was meant for another, they may have to pay for it because it wouldn’t be fair to let them keep the benefit without acknowledging the provider's effort or expense. Essentially, it ensures fairness in situations where a contract doesn’t explicitly exist.
