Key takeaways
- Put your partnership agreement in writing so ownership, profit shares, partner responsibilities, and exit processes are clear from the start.
- Pick a profit-sharing model and document the math and timing so you know how to distribute profits and losses.
- Define decision-making processes, including which decisions a partner can make alone, which need a vote, and how to handle disputes.
- Include exit clauses and buyout provisions so a partner's departure doesn't force you to dissolve the business entirely.
What is a business partnership agreement?
A business partnership agreement is a legally binding document that defines the rights, responsibilities, and financial arrangements between two or more co-owners of a business. It covers how profits are split, how decisions are made, and what happens if a partner wants to leave.
The purpose of a partnership agreement is to guide a business relationship and minimize disputes by defining expectations for everything from managing daily operations to taking out loans to dissolving the partnership. Whether you're forming a general partnership, a limited partnership (LP), or a limited liability partnership (LLP), a written agreement helps protect every partner's interests.
The Small Business Administration outlines several business structures, including partnerships, and highlights the importance of understanding each structure's legal and tax implications before you get started. The IRS also has details on partnerships for a deep dive on everything from forming to ending a partnership.
What should a business partnership agreement include?
A business partnership agreement should include the names and roles of all partners, ownership percentages, how profits and losses are divided, the process for making major business decisions, what happens when a partner exits, and how disputes are resolved. Without a written agreement, partnerships default to the Uniform Partnership Act (UPA) or its revised version (RUPA), a set of standard rules that may not reflect what partners actually want.
A comprehensive partnership agreement typically covers these key elements:
- Partner names and roles: Identify each partner and what they're responsible for in the day-to-day business.
- Ownership percentages: Define each partner's share of the business, which often determines voting power and profit distribution.
- Profit and loss distribution: Specify how financial gains and losses are divided among partners and when distributions happen.
- Decision-making authority: Clarify which decisions each partner can make independently and which require a group vote.
- Partner authority and binding power: Specify which partners can sign contracts, take on debt, or otherwise legally obligate the business without requiring approval from the other partners.
- Capital contributions: Record what each partner is contributing to the business, whether it's cash, property, or services.
- Exit clauses and buyout provisions: A buy-sell agreement is a provision that determines how a departing partner's ownership share is valued and transferred. Without an exit clause, a partner's departure could force you to dissolve the entire partnership.
- Dispute resolution: Outline how disagreements between partners are handled, such as requiring mediation before legal action.
- Partnership duration: State whether the partnership has a set end date or continues indefinitely.
- Amendment process: Describe how the agreement can be changed if all partners agree, including whether amendments require unanimous or majority consent.
You may also want to include clauses covering non-compete agreements, confidentiality expectations, and insurance requirements. The more scenarios you address upfront, the less room there is for misunderstandings later.
Here's a quick reference for the key sections of a partnership agreement and what it covers:
- Ownership: Each partner's percentage stake
- Profits and losses: How financial results are divided
- Decision-making: Who can authorize what
- Partner authority: Who can legally bind the business
- Exit and buyout: What happens when a partner leaves
- Amendments: How the agreement can be updated
- Dispute resolution: How conflicts are handled
How to split profits in a partnership
Profit splits in a business partnership are determined by the partnership agreement and can be structured equally, proportionally to capital contributions, or based on each partner's role. You can split up partnership profits in many different ways, including:
- Equally: Each partner gets an equal share; for example, if there are four partners, they each get 25% of the profits.
- Based on ownership: Profit shares are based on ownership, as determined by capital accounts.
- Pre-defined ratios: Profit shares are based on percentages agreed to by the partners, with no regard to ownership percentages.
- Guaranteed payments plus percentage of profits: A partner gets a set amount, typically in exchange for working in the business, plus a percentage of profits.
Regardless of how you decide to split up profits, make sure it's clearly defined in your partnership agreement. You should also specify how often distributions happen, whether that's monthly, quarterly, or annually.
According to IRS Publication 541, guaranteed payments and a partner's share of profit are taxed as income, but distributions are generally not taxable unless they exceed your basis in the partnership. Each partner reports their share of income on their personal tax return, regardless of whether profits were actually distributed.
The IRS has more details in the instructions to Form 1065 (U.S. Return of Partnership Income).
How decisions get made in a partnership
In a partnership, decision-making authority is defined in the partnership agreement; some decisions can be made by a single partner, while others require group approval. A managing partner is the partner designated to handle day-to-day business decisions without requiring approval from other partners. Major decisions, such as taking on debt or bringing in a new partner, typically require unanimous or majority consent.
The partnership contract or agreement should outline how you make decisions; the more partners you have, the more important this is. It's worth distinguishing between routine decisions that a single partner can handle and major decisions that affect the business's direction or finances. The agreement should explain:
- each partner's authority for making certain types of decisions
- who can contractually bind the partnership by signing legal documents
- which decisions require a vote
- whether you need unanimous or majority approval in a vote
- how to resolve disputes
Clearly defining these boundaries helps prevent conflicts and keeps the business moving when quick decisions are needed.
How to write a partnership agreement step by step
Ready to get started? Here's a step-by-step overview of how to write a partnership agreement. While the process may look different depending on your business, these steps cover the basics for most small partnerships.
1. Brainstorm
Get the partners together to talk about the business's purpose and each partner's roles. Aligning on goals and responsibilities early prevents disagreements once the business is running. This is also the time to discuss your long-term vision for the business and what each partner expects to contribute.
2. Determine contributions
List the cash, assets, and loans provided by each partner. These contributions typically set each partner's initial ownership percentage and capital account balance.
3. Decide how to allocate profits
Allocation may vary based on capital contributions, personal preferences, and each partner's role in the company. Even if partners plan to split everything equally, documenting this prevents misunderstandings during tax season.
4. Start with a template
Use a template to make sure you've covered everything. Have a partner meeting to discuss anything you've overlooked, including exit clauses, dispute resolution, and amendment processes. A template gives you a solid starting point, but don't treat it as one-size-fits-all; every partnership has unique needs.
5. Hire a lawyer
Use a lawyer to draft the final agreement based on your notes or to look over the template before finalizing it. A lawyer can catch gaps that may cause problems later, especially around liability and tax obligations. This is particularly important if your partnership involves significant assets, real estate, or intellectual property.
6. Sign
Have all the partners sign the agreement. Each partner should keep a copy, and if needed, provide one to your state's Secretary of State with your formation documents. Store the original with your business records in a secure location.
Mistakes to avoid with business partnership agreements
The biggest mistake is starting a partnership without a formal written agreement. Without one, you're leaving your business relationship to default state laws that may not match your intentions. To avoid other mistakes, keep these tips in mind:
- Plan for disputes. Disagreements are inevitable, but a plan can minimize their impact. A mediation clause, for example, can save you thousands in legal fees compared to going straight to court
- Restrict transfers. Protect your business by prohibiting transfers to competitors or other outsiders as desired. Without transfer restrictions, a partner could sell their share to someone you'd never want as a business partner
- Give partners first right of refusal. If you allow outside transfers, give the current partners first right of refusal. Then, if a partner gets an offer, they must give the other partner(s) a chance to purchase their shares at the rate offered by the outside buyer
- Address death or incapacity. Under the Revised Uniform Partnership Act (RUPA), a partner's death causes dissociation but does not automatically dissolve the partnership; the business continues by default. However, your agreement should still spell out what happens to the deceased partner's ownership interest. Options include passing ownership to the partner's heirs so they can sell, letting the partner's heirs take over the partner's role, or allowing the other partners to buy out the deceased partner's shares (often funded by life insurance)
- Include an exit clause. Without one, a partner's departure could force you to dissolve the business entirely and negotiate terms from scratch
- Review the agreement regularly. Business circumstances change over time, and your agreement should keep pace. Schedule a review at least once a year or whenever a major change occurs, such as a new partner joining or a shift in profit-sharing arrangements

FAQs on business partnership agreements
Here are answers to common questions about partnership agreements.
Do I need a lawyer to write a partnership agreement?
You aren't legally required to hire a lawyer to write a partnership agreement, but it's strongly recommended for complex arrangements. A lawyer can make sure the agreement complies with your state's laws, covers edge cases like partner death or incapacity, and holds up in court if a dispute arises. Many small business owners use a legal template as a starting point, then have an attorney review the final document before signing.
What happens if a partner wants to leave the business?
When a partner wants to leave, the exit process is governed by the partnership agreement's exit clause. This typically includes a buyout provision that sets the method for valuing the departing partner's share and the timeline for payment. Without an exit clause, partners may need to dissolve the entire partnership or negotiate terms from scratch, which can be costly and contentious. Having a clear exit provision protects all partners from the start.
Can a partnership agreement be changed after it's signed?
Yes, a partnership agreement can be amended after it's signed, provided all partners agree to the changes and the amendment is documented in writing. Most partnership agreements include a clause outlining the formal amendment process, such as requiring unanimous written consent. It's good practice to review and update the agreement whenever there's a significant change in the business, such as adding a new partner, changing ownership percentages, or shifting roles.
Is a handshake agreement legally binding for a partnership?
A handshake or oral agreement can be legally binding, but it's very difficult to enforce in practice. Without a written document, there's no clear record of what was agreed to, which makes disputes nearly impossible to resolve fairly. In the absence of a written partnership agreement, state law applies by default. Laws vary, but many states mandate equal profit and loss shares regardless of each partner's actual contribution.
What is the Uniform Partnership Act?
The Uniform Partnership Act (UPA) is a standard set of laws adopted by most US states that governs how partnerships operate when no formal written agreement exists. It covers default rules for profit sharing, partner liability, and dissolution. The UPA applies automatically unless partners create their own written agreement with different terms, which is why having a partnership agreement is so important.
