Partnership Agreement Between Founders: What to Agree Before Launch

When a company has two or more owners, it is better to document their arrangements before major spending, investment, or conflict begins. A partnership agreement helps establish who makes decisions, how ownership and money are handled, what happens when a founder leaves, and how the company responds to deadlock.

The name and legal form of the document depend on the country and type of company. It may be called a founders’ agreement, shareholders’ agreement, members’ agreement, partnership agreement, or operating agreement. There is no single template that works in every country. The final document must be aligned with the articles, mandatory corporate documents, and the law governing the company.

At a glance: seven questions founders should answer

Before launching a joint business, the founders should put clear answers to at least seven questions in writing:

• who contributes what to the company;
• who owns each interest and when ownership may change;
• who manages the business and which responsibilities belong to each person;
• which decisions require the consent of other owners;
• how profits, losses, and additional funding are handled;
• who owns the product, brand, customer data, and other work created for the business;
• what happens in a dispute, long-term incapacity, transfer of an interest, or founder departure.

An agreement cannot guarantee that disputes will never arise. Its purpose is to reduce uncertainty and give the owners a process they accepted in advance.

How a founders’ agreement differs from constitutional documents

Articles of association and other mandatory corporate documents describe the company in the form required by local law. A private agreement between the owners usually goes further into their relationship: roles, restrictions on transfers, funding, confidentiality, departure, and deadlock.

The documents must work together. If the private agreement conflicts with mandatory law or the company’s articles, a planned mechanism may not operate as expected. The founders should therefore choose the jurisdiction and legal form first and then review the whole set of documents for consistency.

When an agreement is particularly useful

A written agreement is not only for venture-backed startups or equal ownership structures. It is especially useful when:

• one founder contributes money while another contributes time, technology, or business relationships;
• ownership is not divided equally;
• a founder keeps another job or participates in another business;
• the company may raise investment or issue employee equity;
• important decisions require unanimous approval;
• the business depends on intellectual property initially owned by a founder;
• the owners live in different countries;
• the founders are already considering a future sale or departure.

The more the founders differ in contribution, workload, and expectations, the more dangerous it is to leave their arrangements in messages or conversations alone.

What to include in a partnership agreement

1. Parties, business purpose, and effective date

Identify the parties, the company or project covered by the agreement, and the date on which each provision starts to apply. If the company has not yet been incorporated, state which arrangements apply before incorporation and which ones must later be reflected in corporate documents.

2. Contributions and ownership

Record what each founder will contribute: cash, property, equipment, code, rights to existing work, working time, or other resources. For non-cash contributions, describe how they will be valued and when they will be transferred to the company.

State the initial ownership split and the events that may change it. A promise to work on a project does not necessarily have the same effect as transferring an asset or receiving a legally effective ownership interest.

3. Roles and workload

Answer practical questions: who leads sales, finance, product, and the team; how much time each founder commits; whether participation in competing projects is allowed; and whether a founder receives salary or fees in addition to ownership.

Separate ownership from employment and management. Holding shares does not by itself define a person’s obligations as a director, employee, or contractor.

4. Voting and reserved matters

Set the ordinary decision-making process and list matters that require a qualified majority or unanimous approval. They often include:

• issuing new interests or changing the capital structure;
• large loans and transactions;
• approving the annual budget;
• declaring dividends;
• selling material assets;
• changing the main business activity;
• admitting a new owner;
• reorganising or closing the company.

The list and voting thresholds must be checked against local company law and the constitutional documents.

5. Money, distributions, and additional funding

Explain who approves spending, who can access bank accounts, and which payments require a second approval. Separately agree how profits may be distributed, how reserves are created, and how additional funding decisions are made.

If the company needs more money, the founders should know whether it will be treated as an additional contribution, a shareholder loan, or external finance. These terms are difficult to negotiate after the company has already run short of cash.

6. Intellectual property and confidentiality

Identify who owns the software, designs, customer records, domains, trademarks, methods, and other work created before and after launch. If a founder or contractor transfers rights to the company, a reference in the founders’ agreement may not be enough; the relevant jurisdiction may require separate assignments.

Confidentiality, non-compete, non-solicitation, and similar restrictions also need a local legal review. A restriction drafted too broadly may fail to provide the intended protection.

7. Transfers and new owners

Agree whether an owner may transfer an interest freely, whether the other owners receive a prior offer, and who approves a new participant.

For a possible sale of the company, founders may discuss rights to join a transaction and obligations to sell on agreed terms. These mechanisms are often called tag-along and drag-along rights, but their wording and enforceability depend on the jurisdiction.

8. Founder departure and vesting

If ownership is earned through future work, the parties may link the final entitlement to time served or milestones achieved. This is commonly called vesting. The agreement should clearly cover the schedule and the consequences of voluntary departure, dismissal, breach, or long-term inability to work.

The buyout price and valuation process should be capable of calculation. A reference to a “fair price” without a method, deadline, or independent valuation simply postpones the dispute.

9. Deadlock and disputes

In a 50/50 company, a disagreement on a key matter can stop the business. The agreement may provide staged negotiations, an independent mediator, escalation to another decision level, or a defined buyout process.

The parties also need to address governing law, the method of dispute resolution, and the place where a dispute will be heard. These provisions are particularly important when the owners and the company are based in different countries. They should be reviewed by counsel familiar with the chosen jurisdiction and the cross-border consequences.

10. Death, incapacity, and closure

Difficult scenarios are easier to address before they occur. The document may cover what happens to a deceased owner’s interest, whether heirs participate in management, when a buyout right arises, and how the interest is valued.

For closure, the agreement should establish how the decision is made and how remaining assets are dealt with. It does not replace the mandatory dissolution procedure in the country where the company is registered.

How to prepare the agreement without relying on a generic template

1. Each founder separately records their contribution, role, income expectations, and acceptable exit terms.
2. The founders compare their answers and identify disagreements before legal drafting begins.
3. They select the country, legal form, and mandatory corporate documents.
4. They prepare an agreed term sheet and a decision matrix with voting thresholds.
5. A lawyer in the relevant jurisdiction reviews the form, enforceability, and consistency of the documents.
6. The agreement is reviewed after investment, ownership changes, relocation, or a material change in management.

Common mistakes

• Copying a template without checking the country. Similar wording may have different legal effects.
• Discussing ownership only. Roles, time, money, and access to decisions often cause the real conflict.
• Failing to transfer intellectual property. Ownership in the company does not automatically transfer rights to work created by a founder.
• Ignoring departure. Without a valuation method and deadlines, a buyout becomes a new dispute.
• Creating inconsistent documents. The agreement, articles, employment contracts, and owner resolutions must be reviewed together.
• Signing once and never reviewing it. Material changes in the business should trigger an update.

Before signing, use the general contract review checklist. Other practical materials are available in the Contracts section.

Questions and answers

Is a founders’ agreement required to register a company?

The answer depends on the country and legal form. Registration may require a statutory set of documents while a separate agreement between owners remains voluntary. The fact that an agreement is not filed at incorporation does not remove the need to define the owners’ relationship.

Can one template be used in every country?

No. The checklist of business questions may be universal, but the legal text is not. It must be aligned with local law, the articles, ownership structure, and the founders’ actual roles.

Does an agreement help when ownership is split 50/50?

Yes. In that structure, a practical deadlock mechanism is especially important. “We decide together” is not a complete process when a decision is urgent and the votes are evenly divided.

Do friends or relatives need a written agreement?

Personal trust does not define business rules. A written agreement separates expectations from obligations and reduces the risk that the same conversation is remembered differently.

When should the agreement be reviewed?

Review it after changes in ownership, investment, employee equity, leadership, entry into another country, transfer of important intellectual property, or a material change in the business model.
