Ownership & Governance

Authority to Bind a Company

By Tim Nichols

In plain English

The legal power to commit a company to a contract or other obligation. It may come from actual authorization or from the company’s conduct creating reasonable apparent authority. A person’s ownership percentage or claimed title alone does not resolve whether they can bind the business.

Types and key distinctions

Actual Authority

Authority a company or other principal has actually given someone to act on its behalf. It can be express, such as a written signing authorization, or implied from an assigned role and responsibilities. Its scope may be limited by governing documents, resolutions, or instructions.

Apparent Authority

Authority a third party reasonably believes a person has because of the principal's words or conduct. The person's own claim of authority is not enough by itself. A company may face an external obligation even when its representative violated an internal limit the other party did not know about.

Representative Capacity

The role in which a person acts for another person or entity rather than individually. A contract should identify the legal entity and the signer's authorized title or role. Clear capacity language helps establish who undertook the obligation, although separate guarantees or personal promises can still create individual liability.
