Contract LawLegal glossary term
Quick answer
Authority usually means legal power to act on behalf of another. In contracts, it matters because unauthorized actions create personal liability. Before signing, verify the scope of authority in writing.
Definitions
What is authority?
Legal Definition
Authority represents the legal power to act on behalf of another or to make binding decisions. In contracts, authority creates enforceable obligations and rights for the parties. Actual authority differs from apparent authority, which can bind principals even without direct permission.
Plain-English Translation
Authority is like a parent's permission slip allowing a child to stay after school. Without it, the teacher won't release the child, even if the child claims they're allowed to stay.
Contract relevance
Why authority matters in contracts
Without proper authority, contracts can be voided, and the unauthorized party faces personal liability. The relying party bears the risk if they fail to verify authority.

Missing or vague
If authority is missing or vague
Without clear authority provisions, parties may disagree on who can bind the organization to contracts. A signatory might claim authority while the principal denies it, leading to disputes over enforceability. Third parties may face uncertainty about whether to rely on unauthorized representations, creating transactional friction. Courts will examine the circumstances to determine authority, which can result in inconsistent outcomes and increased litigation costs.

Document context
How authority shows up in legal documents
Why does it matter?
Without proper authority, contracts can be voided, and the unauthorized party faces personal liability. The relying party bears the risk if they fail to verify authority.
When does it matter?
Authority becomes critical when a party enters into a contract or takes action on behalf of another. Within 30 days of discovering lack of authority, parties may challenge the agreement.
Where is it usually seen?
Authority appears in agency agreements, power of documents, corporate resolutions, and standard in Article 3 UCC negotiable instruments. Courts examine authority in breach of contract and fraud cases.
Who is affected?
Agents gain the right to bind principals but risk personal liability for unauthorized acts. Principals gain the benefit of representation but face liability for agent actions within their actual authority.
How does it work?
First, determine if authority is express (written or oral) or implied by conduct. Then, verify the scope of authority through documentation or past dealings. Finally, ensure actions stay within the authorized scope to avoid personal liability.
