Selling to a Partner or Co-Owner: California Buyout Agreements Explained

Rokita Law P.C. — Fri, 02 Oct 2026 15:14:43 GMT

Selling your ownership interest to an existing partner or co-owner is a buyout, but the legal process depends on your business structure and governing documents. A partnership interest, LLC membership interest, and corporate shares can each involve different transfer rules, approval requirements, and buyout terms. Before agreeing to a price or signing a buyout agreement, you need to understand what your governing documents require and what California law allows.

What Is a Partner Buyout?

A partner buyout is a sale of your ownership interest to someone who already owns part of the business, not to an outside buyer. That usually means fewer third-party consent issues. It does not mean the deal is simple. The price still has to be set, and the terms still have to be documented.

Why Entity Type Changes the Rules in a Buyout

Partnerships

Check your written partnership agreement first. It often sets the buyout price, notice requirements, and payment terms.

If it’s silent, Corporations Code Section 16701 provides a default. When a partner dissociates and the business continues, the partnership must generally buy that partner’s interest at the amount the partner would have received if the assets were sold at going-concern or liquidation value, whichever is greater, with interest from the date of dissociation. If no price is agreed, payment is due within 120 days of a written demand, and either side can ask a court to set the price.

A written partnership agreement can override this default, which is why the agreement is the first document to pull.

LLCs

The operating agreement controls. Look for:

Transfer restrictions
Right of first refusal terms
Notice requirements to other members
Any consent threshold needed to approve the sale
A stated valuation method or appraisal process

If the operating agreement is silent on member-to-member sales, the transfer generally defaults to whatever the members agree to, subject to any amendment rules the agreement requires.

Corporations

A shareholder or buy-sell agreement typically governs. It usually specifies whether the buyout is:

A cross-purchase, where the buying shareholder buys your shares directly, or
A redemption, where the corporation itself buys back your shares

These carry different tax and control consequences. Without a shareholder agreement, check the bylaws and any restrictions printed on the stock certificates.

Do not assume a rule for one entity type applies to another.

How the Buyout Price Gets Determined

The price comes from one of three places:

Your governing document’s own formula or method, if it has one.
An independent appraisal or negotiated figure, where the document is silent.
The statutory default under Section 16701, for partnerships without a controlling provision.

Common valuation methods include a fixed price stated in the agreement, a formula tied to book value or an earnings multiple, an independent appraisal, or a straight negotiation. Which one applies depends on your documents and financials, and the resulting number is a job for a qualified appraiser or accountant, not a legal argument.

Tax treatment differs depending on how the buyout is structured, sale of a partnership interest, redemption, or an installment sale. Consult a qualified tax professional before finalizing the structure.

If You Can’t Agree on a Price

Many governing documents build in a resolution process for exactly this. If yours doesn’t, or it doesn’t produce an answer both sides accept, the practical options are a jointly selected independent appraiser, mediation, or, for a partnership, the Section 16701 court process. Litigation over valuation is expensive relative to what’s usually at stake, so resolving the price mechanism in the agreement upfront is worth the effort.

How Buyouts Get Financed

Cash, from the buying partner’s own funds
A seller-financed note, with you accepting installment payments, typically secured by the interest itself or other collateral
A bank or SBA loan the buying partner obtains
A corporate redemption, funded by the business itself, more common in corporations than partnerships or LLCs

If you’re financing part of the price through a note, specify the interest rate, payment schedule, default terms, and whether you retain a security interest until it’s paid off. Seller financing offers flexibility but leaves you exposed to the business’s future success.

What the Buyout Agreement Should Address

The purchase price and how it was determined
Payment terms: lump sum, installment note, or a combination
Representations that there are no undisclosed liabilities affecting the price
Releases between you and the buying owner
What happens to your management authority, signing authority, and any personal guarantees on business debt, a buyout doesn’t release you from a guarantee unless the lender separately agrees
Non-compete terms, if requested. California generally voids non-competes under Business and Professions Code Section 16600, but Section 16601 allows a narrow, geographically limited exception when you’re selling your ownership interest, so long as the buyer continues a similar business. Courts construe this narrowly.
Amendments to the governing documents reflecting the change in ownership

What Happens at Closing

Once the buyout is finalized, several steps are completed to officially transfer the ownership interest:

Ownership is transferred: For an LLC or partnership, the ownership interest is formally assigned to the buyer. For a corporation, the shares are transferred to the buyer.
Required approvals are obtained: Any approvals required from the board, members, or other owners are completed.
Payment is made: The buyer pays the agreed amount according to the terms of the buyout agreement.
Personal guarantees are addressed: If the departing owner personally guaranteed a business loan or other debt, the buyout agreement does not automatically release them from that guarantee. The lender must separately agree to release the guarantee.
Business records are updated: Ownership ledgers, operating agreements, shareholder records, and other governing documents should be updated to reflect the new ownership.
Licenses and filings are updated: Any required business licenses, registrations, or government filings should be updated to reflect the ownership change.
Transaction records are kept: Keep copies of the signed buyout agreement, valuation documents, payment records, approvals, and other documents related to the transaction.

Completing these steps helps make sure the ownership change is properly documented and that both sides have a clear record of what was agreed to and completed.

Documents to Gather First

Ownership agreements: Partnership agreements, operating agreements, shareholder agreements, and any amendments.
Financial records: Recent financial statements and business tax returns.
Personally guaranteed debts: A list of business loans or other debts that you have personally guaranteed.
Buy-sell or valuation provisions: Any existing provisions that explain how an owner’s interest can be sold or how the business should be valued.
Past distributions or draws: Records showing money previously distributed or withdrawn by the owners.

Common Mistakes to Avoid

Negotiating a price before checking whether your governing document already sets one
Assuming a partnership buyout right applies to an LLC or corporation
Forgetting personal guarantees survive the buyout
Drafting a non-compete broader than the goodwill actually sold
Skipping written releases
Treating the deal as informal because you already know and trust the buyer

Key Takeaways

Your partnership, operating, or shareholder agreement governs first, not a one-size-fits-all rule.
California partnership law provides a statutory default buyout process, but a written agreement generally overrides it.
LLC and corporate buyouts follow the operating agreement’s or shareholder agreement’s specific terms.
Personal guarantees survive a buyout unless the lender agrees otherwise.
A post-sale non-compete is only enforceable within the narrow scope California law allows.

What Counts as a Breach of Fiduciary Duty Between Business Partners in California

Rokita Law P.C. — Fri, 18 Sep 2026 15:19:50 GMT

When two or more people run a business together, California law treats them as more than co-owners. They are fiduciaries to one another, meaning each partner is legally required to put the interests of the partnership ahead of personal gain. A breach of fiduciary duty happens when a partner crosses that line and acts in a way that harms the business or the other partners for their own benefit.

California Corporations Code Section 16404 sets out the specific duties every partner owes. Understanding what the statute actually requires makes it easier to recognize a real breach, separate it from an ordinary business dispute, and decide whether legal action is warranted.

The Fiduciary Duties Partners Owe Under California Law

California Corporations Code Section 16404 identifies two core fiduciary duties that partners owe to the partnership and to each other: the duty of loyalty and the duty of care. The statute also imposes a separate obligation of good faith and fair dealing. A breach of any of these can give rise to a claim.

The Duty of Loyalty

The duty of loyalty is the strictest obligation a partner carries. Under Section 16404(b), a partner must do three things.

First, account to the partnership for any property, profit, or benefit gained from partnership business, from use of partnership property, or from taking a business opportunity that belonged to the partnership.
Second, refrain from dealing with the partnership as, or on behalf of, a party whose interests are adverse to the partnership.
Third, refrain from competing with the partnership before it dissolves.

Common breaches of the duty of loyalty include:

Diverting a client, contract, or opportunity that came to the partnership and taking it for a side business.
Self-dealing, such as steering partnership money into a company the partner secretly owns.
Using partnership funds, equipment, or confidential information for personal projects.
Secretly competing against the partnership while still a partner.
Taking undisclosed commissions, kickbacks, or rebates connected to partnership business.

The Duty of Care

The duty of care sets a floor for how carefully a partner must manage the business. Section 16404(c) limits this duty to refraining from grossly negligent or reckless conduct, intentional misconduct, or a knowing violation of law. This is an important distinction. An ordinary mistake or a business decision that simply turns out badly does not breach the duty of care. The conduct has to rise to the level of gross negligence or worse.

Examples that can support a breach of the duty of care include:

Overspending the partnership budget while ignoring obvious and foreseeable financial risk.
Signing major contracts without any effort to investigate whether the other side could perform.
Failing to keep basic financial records, leading to serious and avoidable losses.
Knowingly violating a law or regulation that exposes the partnership to liability.

The Obligation of Good Faith and Fair Dealing

Section 16404(d) requires each partner to discharge their duties and exercise their rights consistently with the obligation of good faith and fair dealing. This obligation runs through every partnership decision. A partner who technically follows the partnership agreement but manipulates the process to squeeze out another partner, hide information, or gain an unfair edge may still be acting in bad faith.

What Does Not Count as a Breach

Not every conflict between partners is a breach of fiduciary duty. California law makes several points clear. A partner does not violate a duty simply because their conduct also serves their own interest, as stated in Section 16404(e). Pursuing profit is expected. The problem arises only when a partner advances personal interests at the expense of the partnership through disloyalty, gross carelessness, or bad faith.

Likewise, honest disagreements about strategy, ordinary business losses, and reasonable decisions that later prove wrong do not create liability. Competing with the business after the partnership has dissolved is generally permitted, because the duty not to compete applies before dissolution.

How a Breach of Fiduciary Duty Is Proven

To succeed on a breach of fiduciary duty claim in California, the aggrieved partner generally must establish that a fiduciary duty existed, that the other partner breached it, and that the breach caused measurable harm to the partnership or to the partner. Evidence often comes from financial records, bank statements, emails, contracts, and testimony that shows the diverted money, the hidden transaction, or the taken opportunity. A forensic accounting is frequently used to trace funds and quantify the loss.

Remedies Available to an Aggrieved Partner

California partners have several potential remedies when a breach occurs. A partner can seek monetary damages for the losses caused by the breach. Courts can order disgorgement, which forces the breaching partner to give up profits wrongfully obtained. A formal accounting can be demanded to reveal the true state of the partnership finances. In cases where assets or operations are at risk during the dispute, a partner may petition for injunctive relief to freeze harmful conduct while the case proceeds. In serious cases, the breach can support removal of the partner or dissolution of the partnership.

When to Speak With a Business Litigation Attorney

Fiduciary disputes tend to escalate quickly, and evidence can disappear once a partner realizes they are being watched. If you believe a business partner is diverting money, taking opportunities, or running the business into the ground through reckless conduct, acting early protects both your rights and the value of the business. A California business litigation attorney can review the partnership agreement, evaluate whether the conduct meets the legal standard for a breach, and advise on the fastest path to protect partnership assets.
