Statutory text
Bare law
(1) Subject to the provisions of section 22, the act of a partner which is done to carry on, in the usual way, business of the kind carried on by the firm, binds the firm.
The authority of a partner to bind the firm conferred by this section is called his ‘implied authority’.
(2) In the absence of any usage or custom of trade to the contrary, the implied authority of a partner does not empower him to—
(a) submit a dispute relating to the business of the firm to arbitration,
(b) open a banking account on behalf of the firm in his own name,
(c) compromise or relinquish any claim or portion of a claim by the firm,
(d) withdraw a suit or proceeding filed on behalf of the firm,
(e) admit any liability in a suit or proceeding against the firm,
(f) acquire immovable property on behalf of the firm,
(g) transfer immovable property belonging to the firm, or
(h) enter into partnership on behalf of the firm.
Central rule and applicability
Subject to Section 22, a partner's act binds the firm where it carries on, in the usual way, business of the kind the firm conducts. In the absence of contrary trade usage or custom, implied authority does not cover the listed arbitration, own-name banking, compromise, litigation, immovable-property and partnership-entry acts.
Limits and related provisions
Being a partner does not mean unlimited authority. The subsection (2) list concerns implied authority and expressly recognizes contrary trade usage or custom; separately established authority may require another analysis. Check Section 20's agreed extensions or restrictions and Section 22's manner of binding the firm, together with state law.
Hypothetical business example
Hypothetical: A trading partner buys ordinary stock but also proposes opening the firm's bank account in the partner's personal name. The transactions are assessed separately: ordinary inventory purchasing does not establish implied authority for the specifically excluded banking arrangement.
Practical decision flow
Identify the act and compare it with the firm's actual kind of business and usual manner of conducting it.
Check the subsection (2) exclusions and any evidenced contrary trade usage or custom.
Review specific authority, deed restrictions and Section 22 before representing that the firm is bound.
Check the applicable state law
This guide explains the central Section 19 baseline. State amendments, notifications and rules can affect its application. Confirm the law applicable to the firm's location and the relevant partnership agreement before acting.
