Do you need a lawyer for a partnership agreement? The technically accurate answer is no — California does not require a written partnership agreement for a general partnership to exist. But operating a business with another person without a written agreement is a financial decision. Just one made without documentation.
What Happens Without a Partnership Agreement
Under California's Revised Uniform Partnership Act, a general partnership formed without a written agreement is governed by the state's default rules. Each partner has equal management rights. Profits and losses are split equally. Any partner can bind the partnership in contracts. Any partner can trigger dissolution.
These defaults may not match your actual intentions. If one partner is contributing more capital, more time, or more specialized expertise, "equal" is rarely actually equal.
What a Partnership Agreement Actually Covers
A properly drafted partnership agreement addresses: ownership percentages and capital contributions, how profits and losses are allocated, who has decision-making authority and for what types of decisions, what happens when a partner wants to leave, how disputes are resolved, and what triggers dissolution of the partnership.
It also addresses the scenarios that feel uncomfortable to discuss at the beginning of a business relationship — which is precisely why they need to be documented before the relationship is tested by them.
The Cost of Skipping It
Partnership disputes are among the most expensive business litigation categories in California. The absence of a written agreement doesn't prevent disputes — it makes them harder to resolve and more expensive to litigate. Courts spend significant time determining what the parties intended when they didn't write it down.
The cost of a properly drafted partnership agreement is a fraction of the cost of a partner dispute. This is not a close comparison.
When to Get Legal Help
You should work with an attorney for a partnership agreement when the stakes are real: when you are contributing capital, when the partnership owns intellectual property, when you are signing client contracts in the partnership's name, or when any partner's departure would create a genuine business problem. If all of those things are true — which they usually are — this is not a DIY document.
