Define: Acts or Omissions

What Acts or Omissions Means in a Contract

Acts or Omissions is a phrase used to describe the full spectrum of conduct that a party might engage in while performing under a contract, whether that conduct involves doing something wrong or failing to do something required. The term deliberately pairs positive action with inaction, closing a gap that might otherwise let a party escape responsibility simply because harm arose from neglect rather than a deliberate step.

This wording is common in clauses dealing with liability, indemnification, and authority. It signals that both parties intend for consequences, whether financial loss, injury, or reputational harm, to be addressed regardless of whether they stemmed from something a person did or something they failed to do. A party granted authority under a Letter of Authority or similar instrument is typically held accountable for both categories of conduct.

Understanding this phrase matters because contracts often allocate risk based on fault, and fault can arise from either an affirmative step or a missed obligation. Recognizing that both are captured helps parties assess their true exposure under an agreement.

How Acts or Omissions Is Defined or Measured

There is no single universal test for what qualifies as an act or omission; the measurement depends on the standard of care set out in the contract and, where relevant, the law governing the contract. Typically, an act is a discrete, identifiable step taken by a party, while an omission is a failure to perform a duty that the contract or a reasonable standard required.

Courts and drafters generally look at whether the party had a duty to act in the first place. Without an underlying obligation, whether contractual or imposed by law, an omission may not carry legal weight. This is why contracts frequently pair the phrase with qualifiers such as negligent, willful, or reckless, to clarify the threshold of fault required before liability attaches.

• Negligent acts or omissions: failure to meet a reasonable standard of care.
• Willful acts or omissions: intentional or deliberate conduct causing harm.
• Acts or omissions within the scope of authority: conduct tied to a role or delegated power.

Where Acts or Omissions Appears in Agreements

The phrase surfaces most often in indemnification clauses, limitation of liability provisions, and insurance-related agreements. It also appears in employment and agency contexts, where a business wants to make clear that it is responsible, or not responsible, for the conduct of representatives acting under delegated authority.

In industries such as healthcare, construction, and finance, where professional judgment and physical safety intersect with contractual duties, acts or omissions clauses are especially important. A contractor's failure to inspect equipment, or a financial adviser's failure to disclose a risk, can both trigger liability under this language.

The phrase also appears in documents establishing delegated authority, such as a Certificate of Authority, where a principal defines the boundaries of an agent's power and the consequences if that agent's acts or omissions exceed or fall short of that authority.

Why the Exact Wording Matters

Precise drafting determines whether a party can be held liable for passive failures as well as active mistakes. If a clause only references acts, a party might argue that a failure to act falls outside the provision entirely, potentially leaving significant gaps in accountability.

The qualifiers attached to the phrase, such as gross negligence, willful misconduct, or ordinary negligence, materially change the scope of liability. A clause capturing only willful acts or omissions sets a much higher bar than one capturing negligent acts or omissions, and this distinction often becomes central in disputes.

Ambiguity in this phrase can also affect insurance coverage, since many policies are written to respond specifically to negligent acts, errors, or omissions. Misalignment between contract language and policy language can leave a party without the protection it assumed it had.

Drafting Considerations

When drafting or reviewing a clause containing this phrase, consider whether it should be limited to conduct within the scope of employment or authority, or whether it should extend more broadly. Overly broad language can expose a party to liability for conduct it never intended to cover, while overly narrow language can leave real risks unaddressed.

Consider pairing the phrase with a clear standard of care and, where appropriate, a cap on liability. It is also worth specifying whether the clause survives termination, since acts or omissions occurring near the end of a contractual relationship can still give rise to disputes long after the agreement ends, sometimes prompting a formal notice before litigation begins.

Finally, ensure consistency across related documents, including insurance certificates, delegation instruments, and indemnity provisions, so that the scope of acts or omissions is uniformly understood and does not create unintended coverage gaps or liability exposure.
