Legal Definitions - sub suo periculo

sub suo periculo is a Latin legal phrase that translates to "at his own risk." Historically used in legal contexts, it describes a situation where an individual or party undertakes an action, enters into an agreement, or proceeds with a particular course of conduct with the understanding that they alone bear the responsibility for any potential negative consequences, losses, or damages that may result. It signifies that the risk of harm or failure rests solely with that individual or party, and they cannot typically hold others accountable if those risks materialize.

Here are some examples illustrating this concept:

• Imagine a homeowner who insists on using a specific, unproven type of roofing material for their new house, despite their contractor's professional advice against it due to concerns about its durability in the local climate. If the homeowner signs an agreement explicitly stating they accept the risk of the material failing prematurely, they are proceeding with that choice of material sub suo periculo. This means that if the roof later leaks or deteriorates due to the material's unsuitability, the financial burden for repairs would fall on the homeowner, not the contractor.

• Consider a person attending a public event where the organizers have clearly posted signs warning attendees that they enter a specific, designated "high-risk" zone (e.g., a mosh pit at a concert, or a viewing area near a demolition site) at their own risk. If an individual chooses to enter this zone and subsequently sustains a minor injury that is a foreseeable consequence of being in such an area, they would be considered to have entered sub suo periculo. They acknowledged and accepted the heightened dangers associated with that specific location, potentially limiting their ability to claim damages from the organizers.

• In a historical commercial transaction, if a merchant purchased a large quantity of goods without thoroughly inspecting them, despite having the opportunity to do so, and a significant portion of the goods later turned out to be defective, the merchant would have acquired the goods sub suo periculo regarding those defects. This implies that by foregoing due diligence, they accepted the inherent risk of hidden flaws, and might not have legal recourse against the seller for the quality issues.
