Legal Definitions - obligatio quasi ex contractu

The Latin term obligatio quasi ex contractu refers to a legal obligation that arises in situations where there is no formal contract between parties, but the law imposes a duty on one party to act as if a contract existed. This concept is rooted in the principle of preventing unjust enrichment, meaning that one person should not unfairly benefit at the expense of another.

Essentially, it's a legal duty that mimics a contractual obligation, created by law rather than by mutual agreement, to ensure fairness and equity between individuals.

• Example 1: Mistaken Payment

  Imagine a bank accidentally deposits an extra $1,000 into your checking account due to a clerical error. You did not ask for this money, nor did you enter into any agreement with the bank to receive it. However, the law imposes an obligatio quasi ex contractu on you to return the mistaken deposit.

  How it illustrates the term: Even though there's no contract stating you must return overpaid funds, the law creates an obligation for you to do so. This prevents you from being unjustly enriched by money that rightfully belongs to the bank.

• Example 2: Emergency Services Rendered

  Consider a scenario where a person collapses unconscious in a public park. A passing doctor immediately provides life-saving medical assistance. Once the person recovers, they may have an obligatio quasi ex contractu to pay the doctor for the reasonable value of the emergency services provided.

  How it illustrates the term: The unconscious person could not agree to a contract for medical services. However, because the doctor provided necessary and beneficial aid, the law implies an obligation for the recipient to compensate the provider, preventing the recipient from unfairly benefiting from the doctor's professional assistance.

• Example 3: Unsolicited Property Preservation

  Suppose you are on an extended vacation, and a severe storm damages a portion of your roof, causing water to leak into your house. Your neighbor, noticing the damage and knowing you are away, hires a reputable roofing company to make emergency repairs to prevent further, more extensive damage to your property. Upon your return, your neighbor presents you with the bill for the emergency repairs.

  How it illustrates the term: You never contracted with your neighbor or the roofing company. However, because your neighbor acted reasonably to protect your property from significant harm, and you benefited from these necessary actions, the law may impose an obligatio quasi ex contractu for you to reimburse your neighbor for the reasonable cost of the repairs. This ensures your neighbor is not out-of-pocket for an action that directly benefited you and prevented greater loss.
