Partnerships are built on trust, fairness, and mutual confidence. Every partner acts as both an owner and an agent of the firm, which means they owe legal and ethical duties to one another. These duties ensure smooth functioning, protect the partnership’s assets, and prevent conflicts that may harm the business.
Below are the core duties of partners, explained clearly and expanded with practical meaning and implications.
1. Duty to Perform True Services
Every partner must:
- Maintain accurate accounts
- Keep authentic vouchers and records
- Allow fair inspection of books by other partners
This ensures transparency within the firm. True services prevent suspicion and promote trust, especially when financial transactions are involved.
Case Scenario
If Partner A collects customer payments but does not record them properly, other partners may suspect misuse. Keeping transparent records prevents conflict and protects financial accuracy.
2. Duty to Be Sincere, Faithful, and Careful
Partners must perform their roles with:
- Honesty
- Fairness
- Diligence
- Loyalty
A partner should never act in a way that harms another partner or the firm. Carelessness, favoritism, or betrayal directly violates this fiduciary duty.
Case Scenario
Partner B manages supplier orders. Instead of placing timely orders, he delays them carelessly, causing inventory shortages. This negligence harms the firm and violates his duty of care.

3. Duty to Work for the Best Advantage of the Firm
Every partner must act in the best interest of the partnership and focus on:
- Improving profits
- Reducing risks
- Enhancing the firm’s reputation
Decisions should always prioritize the benefit of the collective—not personal gain.
Case Scenario
Partner C gets a chance to buy materials at a lower price but chooses a costlier supplier because of personal friendship. This decision reduces firm profit and breaches his duty.
4. Duty to Provide All Necessary Information
Since each partner acts as an agent for the others, they must:
- Share relevant business information
- Report risks, opportunities, or issues promptly
- Avoid concealing financial or operational details
Failure to inform partners can lead to losses and legal disputes.
Case Scenario
Partner D learns that a major client is planning to cancel a long-term contract. If he keeps it secret, the firm loses the chance to respond or renegotiate.
5. Duty to Compensate for Loss Caused by Fraud
If a partner commits fraud or dishonest conduct, they must:
- Compensate the firm
- Reimburse partners for all resulting losses
- Face legal consequences depending on severity
This rule protects innocent partners from unfair financial damage.
Case Scenario
Partner E secretly takes cash from the firm’s account for personal use. After discovery, he must refund the amount and compensate for additional losses.
6. Duty to Use Partnership Property Properly
Partnership property must be used only for:
- Business purposes
- Activities aligned with the firm’s objectives
A partner cannot use business property—land, machines, vehicles, funds—for private benefit unless all partners agree.
Case Scenario
Partner F uses the firm’s vehicle for personal travel for a month, increasing fuel and maintenance expenses. This is improper use and violates partnership rules.
7. Duty to Conduct Business Without Remuneration (When No Agreement Exists)

Unless stated in the partnership agreement:
- Partners are not entitled to salary or commission
- They work based on mutual contribution, not employment terms
Profit sharing is the default form of compensation.
Case Scenario
Partner G handles marketing activities and tries to charge the firm a monthly salary. Without a written agreement, he cannot receive extra payment.
8. Duty to Share Losses Equally (Unless Stated Otherwise)
If there is no written agreement, losses must be:
- Shared equally among partners
- Regardless of capital contribution or effort
However, partners may decide a different ratio by mutual agreement.
Case Scenario
If the firm suffers a loss of $30,000 and there are three partners without an agreement, each must bear $10,000.
9. Duty to Compensate for Intentional Neglect
If a partner’s intentional negligence leads to loss—such as ignoring deadlines, mismanaging funds, or failing to act—they must:
- Indemnify (compensate) the firm
- Restore any financial damage caused
This encourages responsible and timely behavior.
Case Scenario
Partner H intentionally ignores customer complaints, causing a major client to leave. He may be held responsible for resulting financial damages.
10. Duty Not to Carry on Competing Business
As long as the partnership exists, partners must not run a competing business. Doing so may:
- Create conflict of interest
- Divert customers
- Misuse partnership knowledge
If a partner violates this, the firm may claim profits earned from such competing activity.
Case Scenario
Partner I secretly opens another store selling the same products as the partnership. The other partners can claim the profits made from this competing business.
11. Duty to Maintain Business Secrecy
Partners must protect confidential business information such as:
- Financial data
- Client lists
- Pricing strategies
- Trade secrets
Any leakage or breach can lead to personal liability.
Case Scenario
Partner J leaks pricing strategy to a competitor. This directly harms the business and makes him personally liable.
12. Duty Restricting Transfer of Interest
A partner may not transfer their share to a third party without consent because:
- Partnerships depend on mutual trust
- New members must be acceptable to all
Transfer without approval does not make the outsider a partner—it only entitles them to share in profits, if allowed.
Case Scenario
Partner K tries to sell his interest to a friend without informing others. This is invalid because third parties cannot become partners automatically.

13. Duty to Act Within the Scope of Powers
Partners must perform activities only within:
- The authority given by the partnership agreement
- Their assigned roles
- Legal boundaries of business operations
Excess or unauthorized actions may lead to personal liability.
Case Scenario
Partner L signs a high-value contract without consulting others, even though the agreement requires joint approval for deals over $25,000. This exceeds his authority.
14. Duty Not to Take Undue Advantage
Partners cannot use business opportunities, customer connections, or company assets for:
- Personal gain
- Competing interests
- Secret profits
If they do, the earned profit legally belongs to the firm.
Case Scenario
A supplier offers Partner M a personal commission for awarding them a contract. Accepting this private benefit is both unethical and illegal.
15. Duty to Return Profit Earned from Partnership Sources
Any profit earned by a partner through the business or its assets must be returned to the partnership.
Examples include:
- Using partnership contacts for personal deals
- Earning secret commissions
- Benefiting privately from firm’s contracts
Such earnings belong collectively to all partners.
Case Scenario
Partner N uses the firm’s raw material to complete a private order and keeps the payment. The profit belongs to the partnership—not to him individually.
Conclusion
A successful partnership depends on the ethics, transparency, and discipline of its partners. These duties—rooted in trust law and contractual obligations—ensure fairness and protect the partnership from internal conflict and financial harm.
By following these principles, partners help create a stable, profitable, and long-lasting business.
