Two women agreed, nothing signed and no split of profits even discussed, to start a nail polish company together. One of them later said the whole thing started as barely more than an idea over wine. A jury found the two were partners anyway, and awarded the one who was pushed out more than a million dollars. Holmes v. Lerner, decided August 20, 1999 by a California Court of Appeal, is the case cited whenever someone asks whether a handshake deal can really create a legal partnership. It can, and the company at the center of it, Urban Decay, is still a recognizable cosmetics brand today.

What follows is the case from the opinion, what made the agreement enforceable with nothing in writing, and the short document that would have settled the question the jury had to answer instead. The broader default rules for an unwritten partnership are in Partnership Without a Written Agreement and What the Law Fills In. This is general information; a lawyer in the founders' state should read any agreement they do have, and help them write one where they have none.

An idea at the kitchen table

Patricia Holmes trained horses. Sandra Lerner, a co-founder of Cisco Systems, had left the company and invested the proceeds, including in horses Holmes trained. The two met in 1993 and became friends. On a 1995 trip to England, the pair got to talking about nail polish colors that did not exist anywhere on the market, unconventional shades with names like Plague and Smog, aimed at a customer the big cosmetics houses were not selling to.

On July 31, 1995, at Lerner's West Hollywood home, the conversation became a decision. Lerner asked Holmes whether they should start a company; Holmes said yes. Lerner said they would 'do everything we can to get the company going', with the two of them handling the creative side and hiring other people to do the operational work. A housekeeper who overheard part of the conversation recalled Lerner saying it would be 'our baby' that they would work on together. None of it was written down, and the two never settled how profits would be split. Holmes went on to contribute creative work to what became Urban Decay while drawing no salary; Lerner used her contacts and capital to raise venture funding. By late 1995, Lerner and her business adviser, David Soward, had cut Holmes down to an offered 1% stake, excluded her from company decisions, and eventually kept her from board meetings altogether. Holmes sued.

From an agreement over wine to a jury verdict

  1. 1993
    Holmes and Lerner meet

    A horse trainer and a Cisco Systems co-founder become friends through Lerner's horses.

    The idea

    The two discuss unconventional nail polish colors nobody else is selling.

  3. July 31, 1995
    The agreement

    At Lerner's home, the two agree to start the company that becomes Urban Decay. Nothing is signed; no profit split is set.

  4. Late 1995
    Holmes is sidelined

    Lerner and adviser David Soward offer Holmes 1%, cut her out of decisions, and later keep her from board meetings.

  5. Aug. 20, 1999
    The ruling

    The Court of Appeal affirms the jury's finding that a partnership existed and the verdict against Lerner.

Why no signature and no profit split mattered less than Lerner argued

Lerner's defense leaned on the absence of the things people assume a partnership needs: a signed document and an agreed split of the money. The court rejected both as requirements. Under California's Uniform Partnership Act, a partnership is simply 'an association of two or more persons to carry on as coowners a business for profit.' Nothing in that definition calls for a writing. As for profit sharing, the statute treats the actual division of profits as evidence that a partnership exists, not as a precondition for one; the court read the legislature's placement of that language, in the evidentiary section rather than the definitional one, as confirming the point directly.

The actual sharing of profits (with exceptions which do not apply here) is prima facie evidence ... which is to be considered, in light of any other evidence, when determining if a partnership exists.

What the jury needed instead was evidence that the two women had agreed to the same thing in the same sense: to be co-owners of a business run for profit, sharing in its direction and its risk, not simply that one was hiring the other or that one was financing an idea the other merely suggested. Lerner's own words at the July 1995 meeting, that the two of them would do everything to get the company going and would be the creative force behind it while others were hired to do the operational work, read to the jury less like an employer talking to an employee than like one co-founder talking to another. That the two never worked out the exact split afterward went to how badly Lerner later treated Holmes, not to whether a partnership had been formed in the first place.

The decision also shows what an unwritten partnership risks for the people around it, not just the founders. The jury's award was split between Lerner and her adviser, David Soward, with Soward separately liable for helping cut Holmes out. The Court of Appeal reversed one theory against Soward (that he had interfered with the Holmes-Lerner contract) for a logical reason: the jury had found Lerner never actually intended to perform the agreement, so there was no valid contract left for Soward to have interfered with, even as the underlying partnership finding against Lerner stood. It reinstated other claims against Soward, for aiding and abetting the breach and for conspiracy, and sent those back for trial.

What the rule means for a founding conversation

The Uniform Partnership Act's modern form keeps the same low bar: 'the association of two or more persons to carry on as co-owners a business for profit' forms a partnership whether or not the people involved intend to form one. That is true in every state that has adopted the uniform act in some form, and it is the reason two founders who agree on an idea, divide up the work, and start spending time and money on it can be partners in the law's eyes well before either of them has thought to use the word. The upside of the rule is real: Patricia Holmes recovered more than a million dollars for a company she was later cut out of, precisely because the law did not require her to have had a lawyer in the room on July 31, 1995. The downside is just as real for the founder who never meant to give anyone a claim on the business: an investor, an adviser, or a friend who pitched in early can later argue, with real legal force, that a partnership existed.

The fix is not a long contract. It is a short one, signed at the point where Holmes and Lerner's conversation would have ended with a decision rather than an understanding.

Sample clause: founders' memorandum
Founders' Memorandum. This memorandum confirms the understanding of [Name A] and [Name B] (the 'Founders') as of [date]: (a) the Founders are forming a business to [one-sentence description of the business]; (b) ownership of the business is [__]% to [Name A] and [__]% to [Name B], subject to a formal operating or partnership agreement to be signed within [30] days; (c) each Founder's initial contribution is as follows: [Name A] contributes [cash, time, assets]; [Name B] contributes [cash, time, assets]; (d) if a formal agreement is not signed within that period, this memorandum governs until it is, and either Founder may require the other to proceed to a formal agreement on these terms or to wind up the business; (e) a Founder who stops actively working in the business forfeits any unvested share of ownership as set out in the vesting schedule to be included in the formal agreement.

This is one page, meant to be signed the day two people agree to go into business, before anything else happens. Paragraph (d) is the safety net: it keeps an informal deal from drifting for years with nothing decided, which is exactly the gap that let Holmes and Lerner's disagreement turn into years of litigation instead of a quick read of a contract.

Founder Vesting Schedules and How to Start a Business Partnership go further into what the formal agreement should say once the memorandum buys time to write one. Holmes v. Lerner is one of 20 decisions summarized in Business Partnership Dispute Cases. Urban Decay is proof the idea at the kitchen table can become a real company; the case is proof that whoever is in the room when it happens may already be a partner, signed or not.
