Partnership & Founder Agreements
A partnership or founder agreement is the written plan for who owns what, who decides what, and what happens if the business changes. If you are starting a company with another person, bringing in an investor, or changing ownership later, this is one of the most important documents to get right.

What partnership and founder agreements cover
A partnership or founder agreement sets the working rules between owners. It can be used for two founders launching a new company, a small team dividing equity, spouses or relatives starting a business together, or existing owners adding someone new.
The exact document depends on the business structure. An LLC is a limited liability company, a business entity that can separate the owners' personal liability from business debts in many situations. An LLC often uses an operating agreement, which is the internal contract that explains ownership, management, voting, profit sharing, and what happens if an owner leaves. A corporation may use founder stock documents, shareholder agreements, bylaws, or other ownership documents.
These agreements often cover:
- each person's ownership percentage or units
- money, work, property, or contacts each person is contributing
- who makes day-to-day decisions and which decisions need a vote
- how profits, losses, and distributions are handled
- whether ownership earns over time through vesting
- what happens if someone quits, dies, becomes disabled, gets divorced, or stops contributing
- whether an owner can transfer or sell their interest
- how disputes are handled
- confidentiality, invention ownership, and non-solicitation terms when appropriate

Who usually needs this service
This service is common for businesses that have more than one owner, or expect to. It matters most when people are putting in different amounts of money, time, experience, or risk.
You may want this service if:
- you are starting a business with one or more co-founders
- you formed an LLC or corporation but never clearly documented ownership rules
- one founder is providing cash and another is providing labor or technical work
- you want ownership to vest over time instead of all at once
- you are bringing in a spouse, relative, friend, adviser, or early employee as an owner
- you want a clear plan if someone leaves or stops pulling their weight
- you expect future investors, lenders, or buyers to review your documents
For a single-owner business with no partners, simple formation may be enough at first. In that case, you may want to start with business entity formation. But if there is shared ownership, shared decision-making, or even a handshake deal about equity, an attorney is often worth the cost.
What an attorney actually does
A licensed business attorney does more than fill in a template. They help turn hard conversations into a workable written agreement that fits your state, your tax posture, and how the business will really run.
An attorney often helps with:
- choosing the right type of agreement for your entity and state
- spotting missing issues before they become disputes
- drafting or revising ownership, voting, vesting, buyout, and exit terms
- aligning the agreement with formation documents already filed with the state
- coordinating related contracts such as an NDA, or non-disclosure agreement, which is a contract to keep certain business information confidential, and an MSA, or master services agreement, which is a contract that sets the general legal terms for ongoing work between a business and a client or vendor
- reviewing founder compensation, reimbursement, intellectual property assignment, and restrictive covenants where allowed by law
- explaining what may need tax or accounting review in addition to legal review
If your company has already filed articles of organization, which are the formation papers filed with a state to create an LLC, or has a DBA, which means "doing business as" and is a business name registration used when operating under a name different from the legal name, the attorney can check that the agreement matches those records.

Typical process and how long it takes
Most partnership and founder agreement projects follow a similar path, though the timing depends on how many owners are involved, how settled the business terms are, and whether there is disagreement.
- Intake and issue spotting. The attorney learns who the owners are, what each person is contributing, and what the business plans to do.
- Document review. If the business already exists, the attorney reviews the formation papers, prior contracts, cap table, and any draft terms.
- Term sheet or key business points. The owners confirm practical questions such as ownership split, vesting, salary, voting, deadlock rules, and exit rights.
- Drafting. The attorney prepares the agreement and any related consents, assignments, or amendments.
- Review and revisions. The owners comment, negotiate, and finalize the terms.
- Signing and follow-up. The agreement is signed, and the attorney may suggest related updates to records or filings.
A straightforward matter may take a few days to a couple of weeks after everyone provides clear information. A more complex matter can take longer, especially when there are multiple founders, investor rights, cross-border issues, or major disagreements.
For related work, you may also need contracts and agreements or business compliance and licensing.
Flat-fee ranges, when DIY may be enough, and when an attorney is worth it
Costs vary by state, document complexity, and whether the work is a fresh draft or a negotiated rewrite. These are general flat-fee ranges only, not quotes.
Common state-dependent flat-fee ranges include:
- basic founder or partnership agreement for a simple two-owner startup: about $500 to $1,500
- custom operating agreement or shareholder/founder documents with tailored voting, transfer, and exit terms: about $1,000 to $3,500
- agreements with vesting, buy-sell terms, intellectual property assignment, or multiple related documents: about $2,000 to $5,000+
- heavily negotiated matters or deals involving several owners, investors, or major restructuring: often higher
DIY may be enough if:
- there is only one owner
- no one else has equity now or promised equity later
- the arrangement is very simple and temporary
- you are using a state default structure while you gather more information
An attorney is usually worth it if:
- there are two or more owners
- people are contributing different things, such as cash, labor, code, equipment, or contacts
- you want vesting or a buyout formula
- one owner may leave soon or is part-time
- friends or relatives are involved and you want clarity without conflict later
- investors, lenders, or acquirers may review the company soon

What to ask an attorney and how free matching works
Before you hire an attorney, ask practical questions that help you compare fit, scope, and price.
Good questions to ask include:
- What document do we actually need for our entity and state?
- What issues do founders usually miss in a business like ours?
- Should ownership vest over time, and if so, how?
- How do you handle founder departures, buyouts, and deadlocks?
- What is included in your flat fee, and what could cost extra?
- Will you review our existing formation papers and contracts?
- Do we also need intellectual property assignment, confidentiality, or employment documents?
- What information should we prepare before you start?
With FoundryCounsel, matching is free for business owners. You share contact details and a short description of the legal need, and we try to connect you with a licensed attorney who handles this type of business-law work. Participating attorneys pay a flat marketing fee to be part of the service.
Please do not send sensitive information through a form, including Social Security numbers, tax ID numbers, immigration details, bank account numbers, or confidential business secrets. Contact details and a short summary are enough to get started.

An honest note
This is general educational information, not legal advice, and does not create an attorney-client relationship. Laws and fees vary by state and change over time — confirm details with a licensed attorney and official sources before you act.
If more than one person owns part of the business, a clear written agreement can prevent expensive confusion later, and we can help you find a lawyer for that.
Common questions
Do we need a founder agreement if we already trust each other?
Usually yes. A written agreement helps protect the relationship by making expectations clear before there is stress, money pressure, or a change in plans.
Can we just use a free template online?
Sometimes a template can help you start a discussion, but it may miss state-specific issues, tax-related consequences, or important exit terms. If more than one person owns part of the business, an attorney review is often a smart step.
Is an operating agreement the same as a partnership agreement?
Not always. An operating agreement is the internal ownership and management contract for an LLC, while a partnership agreement is usually used for a partnership. Some people use the terms loosely, but the right document depends on the entity.
What if one founder already started working without paperwork?
That is common, but it is better to document the arrangement as soon as possible. A lawyer can help sort out ownership, contributions, and intellectual property before the facts get harder to prove.
Does FoundryCounsel give legal advice or review our agreement?
