What is duty?
Legal Definition
A duty creates a legally enforceable obligation to act or refrain from acting. In a contract it triggers performance, and breach invites damages. The key distinction lawyers watch is whether the duty is express or implied.
Plain-English Translation
Think of a duty like a hall pass: it lets a student walk the corridors, but stepping out of line gets the teacher’s reprimand.

Comparison
duty vs similar terms
| Related term | Plain meaning | Main difference from duty |
|---|---|---|
| Obligation | General requirement to do something | Duty is the contractual source of that requirement |
| Right | Permission to receive or do something | Duty imposes a burden, right confers a benefit |
| Warranty | Promise of product condition | Duty may include performance, warranty is a specific type of duty |
Missing or vague
If duty is missing or vague
If a contract omits a clear duty, parties may argue over who must act and when. Ambiguity can turn a simple payment schedule into a dispute over timing. Courts will interpret missing duties against the drafter, leading to unexpected liability. The result is often costly litigation or renegotiation.

Standard in UCC §2-207 sales contracts and in employment agreements.
Who is affected?
Seller gains the right to receive payment, while buyer risks liability for non‑payment; employer obtains a duty to provide a safe workplace, and employee risks disciplinary action for non‑compliance.
How does it work?
