Relations of Partners with Third Parties under the Partnership Act

Updated 10 October 2026 · Fact-checked

Under the Indian Partnership Act, 1932, every partner is the agent of the firm. Acts done in the usual way of the firm's business bind the firm. Each partner is liable jointly and severally for the firm's acts while a partner. To solve a question, test authority, restrictions, third-party knowledge, then liability.

Understand Relations of Partners with Third Parties

A firm is not a separate legal person under the Partnership Act. It is a group of partners. So when the firm deals with an outsider, a partner must act for all the others. The Act solves this by making each partner an agent of the firm for the purposes of the firm's business (Section 18).

The next question is how far that agency goes. Section 19(1) says an act done to carry on, in the usual way, business of the kind the firm carries on, binds the firm. This is the partner's implied authority. A partner in a cloth trading firm who buys stock from a regular supplier binds the firm. The same partner selling the firm's factory building does not act in the usual way of that business.

Section 19(2) lists acts that implied authority does not cover, unless a usage or custom of trade says otherwise. These are: submitting a dispute to arbitration, opening a bank account in his own name on behalf of the firm, compromising or relinquishing a claim, withdrawing a suit, admitting liability in a suit against the firm, acquiring immovable property for the firm, transferring the firm's immovable property, and entering into partnership on behalf of the firm. Partners can still give such power by agreement.

Partners may extend or restrict implied authority by contract among themselves (Section 20). A restriction does not hurt an outsider who does not know of it. The firm is bound by an act within implied authority unless the outsider knows of the restriction, or does not know or believe that person to be a partner. In an emergency, a partner can do what a person of ordinary prudence would do in his own case to protect the firm from loss, and the firm is bound (Section 21).

Liability has two sides. Every partner is liable jointly and also severally for all acts of the firm done while he is a partner (Section 25). The firm is liable for a partner's wrongful act or omission done in the ordinary course of business or with the authority of the partners, to the same extent as that partner (Section 26). The firm must also make good money or property misapplied, as set out in Section 27. Liability can continue after retirement or dissolution until public notice is given (Sections 32 and 45).

Key rules to remember

Partner as agent
Partner = agent of the firm for the purposes of the firm's business (Section 18)
This is the starting point. The firm is bound only through acts of partners as agents.
Implied authority
Act done to carry on, in the usual way, business of the kind the firm carries on → binds the firm (Section 19(1))
Two tests: the act must be for the firm's kind of business and done in the usual way.
Acts outside implied authority
No implied power to: arbitrate; open bank account in own name; compromise or relinquish claim; withdraw suit; admit liability in suit; acquire or transfer immovable property; enter partnership for the firm (Section 19(2))
This applies in the absence of a contrary usage or custom of trade. Remember it as a list of eight.
Restriction of authority
Restriction binds the outsider only if he knows of it, or does not know or believe the person to be a partner (Section 20)
An internal restriction alone does not free the firm from an act within implied authority.
Emergency
Acts of ordinary prudence to protect the firm from loss bind the firm (Section 21)
The purpose must be protecting the firm from loss.
Liability of partners
Every partner is liable jointly with the others and also severally for all acts of the firm done while he is a partner (Section 25)
A creditor may sue one partner for the whole amount. That partner can then claim contribution from the others.
Wrongful acts
Firm liable to the same extent as the partner, if the wrong was in the ordinary course of business or with partners' authority (Section 26)
This covers loss or injury to a third party and also penalties incurred.
Misapplication
Firm must make good the loss if (a) a partner within apparent authority receives money or property and misapplies it, or (b) the firm receives it in the course of business and a partner misapplies it while in the firm's custody (Section 27)
Two limbs. Name the limb that fits the facts.
Retirement and notice
Retired partner and the partners remain liable to third parties until public notice of retirement (Section 32(3)); a retired partner is not liable to one who dealt with the firm without knowing he was a partner
The notice may be given by the retired partner or any partner of the reconstituted firm.
After dissolution
Partners remain liable for acts that would have been acts of the firm until public notice of dissolution (Section 45(1)); authority continues only as necessary to wind up and complete unfinished transactions (Section 47)
Under Section 45(1), the estate of a deceased or insolvent partner is not liable for later acts. Nor is a retired partner who was not known to the dealer to be a partner.

How to solve Relations of Partners with Third Parties questions

Use this order for any problem question on partners and outsiders. It keeps your answer structured and lets the examiner award step marks.

  1. 1Identify the parties: the firm, the acting partner, the other partners and the third party. Note whether the person is really a partner.
  2. 2State the rule: a partner is the agent of the firm (Section 18) and implied authority binds the firm under Section 19(1).
  3. 3Test the act: is it of the kind the firm does, and done in the usual way? Check whether it falls in the Section 19(2) list.
  4. 4Check for a restriction among the partners. Apply Section 20: did the third party know of it, or not know or believe the person to be a partner?
  5. 5If it is a wrong or misapplication, apply Section 26 or 27. If it is a debt or contract, apply Section 25 on joint and several liability.
  6. 6Check timing: was the person a partner when the act was done? Look for retirement or dissolution and whether public notice was given (Sections 32 and 45).
  7. 7Conclude clearly: who is liable, to what extent, and who may claim contribution from whom.

Quickest way: Four-question check

When to use it: Use this for short-note questions and for the reasoning behind an MCQ when time is tight.

  1. Was the person a partner at the time of the act?
  2. Was the act in the usual way of the firm's business, and is it outside the Section 19(2) list?
  3. Did the outsider know of a restriction? If not, the firm is bound.
  4. Then liability is joint and several for every partner who was a partner at that time, subject to notice rules.

Common mistakes in Relations of Partners with Third Parties

  • Saying a restriction among partners always frees the firm.

    Students read the restriction clause and stop.

    Fix: Add the second half of Section 20. The firm is still bound for an act within implied authority unless the outsider knew of the restriction or did not know or believe that person to be a partner.

  • Writing that a partner can never do the acts in Section 19(2).

    The list is remembered as a ban.

    Fix: Say implied authority does not extend to them, in the absence of a contrary usage or custom of trade. Partners can grant such power by agreement.

  • Treating joint and several liability as liability only in proportion to profit share.

    Students mix liability to outsiders with sharing among partners.

    Fix: Each partner is liable for all acts of the firm. The creditor can proceed against any partner for the whole amount. Contribution among partners is a separate matter.

  • Ignoring public notice when a partner has retired.

    Students assume retirement ends liability immediately.

    Fix: Under Section 32(3), liability to third parties continues until public notice, except to those who dealt without knowing he was a partner.

  • Making the firm liable for any wrong of a partner.

    Students overlook the condition in Section 26.

    Fix: State that the wrong must be in the ordinary course of the firm's business or with the partners' authority. A personal wrong outside that is not the firm's.

  • Mixing up Section 26 with Section 27.

    Both deal with partners' wrongful conduct.

    Fix: Section 26 covers loss, injury or penalty caused to a third party. Section 27 covers money or property received from a third party and misapplied.

Worked examples

Example 1

Ravi, Sunil and Meena run a firm trading in electrical goods. By agreement, no partner may buy goods worth more than ₹50,000 without the consent of all. Ravi buys goods worth ₹2,00,000 from Kapoor Traders for the firm, in the usual way. Kapoor Traders does not know of the restriction. Is the firm liable?

Show the solution
  1. Ravi is a partner and so an agent of the firm (Section 18).
  2. Buying electrical goods is business of the kind the firm carries on, and it was done in the usual way. So it is within Ravi's implied authority (Section 19(1)), and it is not in the Section 19(2) list.
  3. The partners may restrict implied authority by contract (Section 20). But the firm stays bound for an act within implied authority unless the outsider knows of the restriction or does not know or believe Ravi to be a partner.
  4. Kapoor Traders did not know of the restriction, and it dealt with Ravi as a partner. So the restriction does not protect the firm.
  5. The firm is bound, and all partners are liable jointly and severally (Section 25).

Answer: Yes. The firm is liable to Kapoor Traders for ₹2,00,000. The restriction binds only the partners among themselves. Sunil and Meena may hold Ravi responsible for breaking the agreement.

Example 2

Anil, Bhavna and Charu are partners in a courier firm. Anil, while delivering parcels in the ordinary course of business, negligently damages the car of a customer, Mr Iyer. Mr Iyer claims ₹80,000 and wants to recover it from Charu alone. Advise.

Show the solution
  1. The act was a wrongful act of a partner done in the ordinary course of the firm's business.
  2. Under Section 26, the firm is liable for loss or injury to a third party caused in this way, to the same extent as Anil.
  3. Under Section 25, every partner is liable jointly with the others and also severally for all acts of the firm done while he is a partner.
  4. Charu was a partner when the act was done. So Mr Iyer may sue Charu alone for the full ₹80,000.
  5. Charu may then seek contribution from the other partners, as the partnership arrangement between them requires.

Answer: Mr Iyer can recover the full ₹80,000 from Charu. Her liability is several as well as joint. She can claim contribution from Anil and Bhavna afterwards.

Exam tips

  • For problem questions, name the section and then apply it. Marks go for the rule, the application and the conclusion.
  • Learn the Section 19(2) list as a set of eight acts and always add the words 'in the absence of any usage or custom of trade to the contrary'.
  • In any retirement or dissolution fact pattern, look for the words 'public notice' and whether the outsider knew the person was a partner.
  • In MCQs, watch for the word 'jointly' versus 'jointly and severally' and for acts that fall outside implied authority.
  • Keep your answer in short numbered points. End with a one-line decision on who is liable.

It is the authority of a partner to bind the firm by acts done to carry on, in the usual way, business of the kind the firm carries on (Section 19(1)). Partners may extend or restrict it by contract (Section 20). It does not cover the acts listed in Section 19(2) unless a usage or custom of trade says otherwise.

Are partners liable jointly or severally?

Both. Every partner is liable jointly with all the other partners and also severally for all acts of the firm done while he is a partner (Section 25). A third party can proceed against any one partner or all of them.

Does the firm pay for a partner's fraud or negligence?

The firm is liable for a partner's wrongful act or omission if it was done in the ordinary course of business or with the authority of the partners (Section 26). The firm is liable to the same extent as the partner. For money or property misapplied, see Section 27.

Is a retired partner still liable to outsiders?

Yes, until public notice of the retirement is given (Section 32(3)). The exception is a third party who dealt with the firm without knowing that he was a partner. Notice may be given by the retired partner or by any partner of the reconstituted firm.
