Partners as Agent of the Partnership
The statutory agency rule at the heart of every general partnership transaction — when a partner’s act binds the firm, when it doesn’t, and how to control the risk.
October 15, 2026 · Reden | Riddell
Core Concept
Under California’s Uniform Partnership Act of 1994 (UPA 1994), each partner occupies a dual role simultaneously: a co-owner of the business and a statutory agent of the firm. Cal. Corp. Code § 16301(1) states the foundational rule — an act of a partner for apparently carrying on in the ordinary course the partnership business binds the partnership, unless (a) the partner had no authority to act, and (b) the person dealing with the partner knew or had received notification that the partner lacked authority. Both conditions must be met to defeat liability.
Outside the ordinary course, the rule flips. Cal. Corp. Code § 16301(2) provides that an act not apparently for carrying on ordinary business binds the partnership only if the act was actually authorized by the other partners. Apparent authority alone is insufficient when the act is extraordinary — the third party takes the risk of dealing with a partner on an unusual transaction without checking actual authority.
The distinction between these two tracks — ordinary-course apparent authority versus out-of-ordinary actual authority — is the central doctrinal divide for partnership liability. Courts ask a contextual question: does the transaction fall within the kind of business the partnership carries on, or is it unusual enough that a reasonable person would inquire further? California courts look at the nature of the partnership’s business, the specific act undertaken, and industry norms when resolving that question.
Bottom Line
Every general partner is a full statutory agent of the firm for ordinary-course transactions, so managing partnership risk means managing partner authority through written agreements, filed statements, and clear internal governance — because a partner’s signature in the ordinary course binds the partnership regardless of what the partnership agreement says internally, if the third party didn’t know.
Key Rules
|
Corp. Code § 16301(1) The Apparent-Authority Rule Any partner’s act for apparently carrying on ordinary-course business binds the partnership. Third party need not verify authority; partnership bears risk of internal restrictions it hasn’t communicated externally. |
Corp. Code § 16301(2) The Actual-Authority Requirement Acts outside the ordinary course require actual authorization. Third party carries risk of dealing with a partner on extraordinary transactions without verifying consent of the full partnership. |
|
Corp. Code § 16303(a)–(f) Statement of Partnership Authority Filed with SoS or county recorder. Grants or restricts partner authority. Constructive-notice effect for real-property transactions — the strongest external control mechanism available to a partnership. |
Corp. Code § 16309 Joint and Several Liability Partners are jointly and severally liable for all obligations of the partnership arising from an act binding under § 16301. Judgment creditor may proceed against any individual partner after obtaining judgment against the entity. |
Applies / Does Not Apply
|
✓ Partner’s Act Binds Partnership ✓ Ordinary-course acts, even without express co-partner authorization ✓ Acts expressly authorized by the partnership agreement ✓ Authority granted in a filed § 16303 Statement of Authority ✓ Wrongful acts in ordinary course (§ 16306 entity liability) |
✕ Does Not Bind Partnership ✕ Ordinary-course act where third party had actual notice of restriction ✕ Outside-ordinary-course acts without actual co-partner consent ✕ Acts denied by a filed § 16304 Statement of Denial ✕ Dissociated partner acts after notice of dissociation (§ 16702) |
In Practice
|
Transactional & Drafting → Draft the partnership agreement to enumerate specific acts requiring unanimous or majority consent — courts narrowly interpret restrictions on agency authority. → For real-property partnerships, file a Statement of Partnership Authority (§ 16303) with the county recorder to create constructive notice of authority limitations. → Upon partner dissociation, file a Statement of Dissociation (§ 16704) immediately to start the 90-day lingering-authority clock under § 16702(b). |
Litigation & Enforcement → To bind the partnership, plaintiff must establish the act fell within ordinary course, or that the partner had actual authority — see CACI 3711 for jury instructions. → Defense defeats § 16301(1) only by proving both prongs: no actual authority AND third party had knowledge of the limitation. Failure to prove the notice element is fatal. → Check SoS and county recorder for filed Statements of Authority — admissible as public records that can prove or defeat the notice element. |
