Buy-Sell Agreement Law in California

A buy-sell agreement is a contract among business owners that governs the transfer of ownership interests upon specific events like death, disability, retirement, or withdrawal. California law requires these agreements to comply with entity-specific formation rules, mandatory share certificate legends for corporations, and community property spousal consent requirements—while providing no default buyout rights for LLC members outside judicial dissolution.

What is a buy-sell agreement?

A buy-sell agreement is a contractual arrangement among business owners that governs the transfer of ownership interests upon specified triggering events. The agreement creates either obligations or rights for shareholders or partners to purchase a departing owner's interest, or obligations or rights for the business entity itself to redeem such interests.

Do I need a buy-sell agreement?

You need a buy-sell agreement if you own a business with other people and want to control who can become an owner, ensure business continuity, and provide liquidity for departing owners or their estates. These agreements are triggered by events including death, disability, retirement, voluntary withdrawal, bankruptcy, or attempted transfer to non-permitted transferees.

What happens when a business owner dies?

When a business owner dies, the buy-sell agreement dictates who can purchase the deceased owner's interest and at what price. The agreement typically uses one of two structures: a cross-purchase agreement, where surviving owners buy the interest directly from the estate, or an entity redemption agreement, where the business entity itself redeems the interest. The choice between these structures has significant tax and estate planning consequences.

How do I fund a buy-sell agreement with life insurance?

You can fund a buy-sell agreement with life insurance using either a cross-purchase or entity redemption structure. In a cross-purchase, individual owners hold policies on each other. In an entity redemption, the business owns the policies. California law expressly authorizes employer-purchased life insurance to fund buy-sell obligations, but only after obtaining the written consent of the individual being insured (Cal. Ins. Code § 10110.1(c)). The insurable interest must exist when the insurance contract becomes effective (Cal. Ins. Code § 10110.1(f)).

What are the requirements for a buy-sell agreement in California?

Corporate Entities: Certificate Notation Requirements

For corporations, California mandates specific disclosures on share certificates to make transfer restrictions enforceable against third parties. Under Cal. Corp. Code § 418(a), certificates must conspicuously state: - That shares are subject to transfer restrictions - That shares are subject to voting agreements or irrevocable proxies - That shares are redeemable - That shares are convertible, with the conversion period

Unless these facts appear on the certificate, no restriction, voting agreement, or proxy is enforceable against a transferee without actual knowledge (Cal. Corp. Code §§ 418(a)(1)–(5), 418(b)).

For close corporations (defined as those with 35 or fewer shareholders under Cal. Corp. Code § 158), certificates must additionally bear a conspicuous legend declaring close-corporation status, the maximum holder number, that noncompliant transfers are void, and referencing restrictions on file with the corporate secretary (Cal. Corp. Code §§ 418(c), 158).

Corporate Repurchase: Financial Capability Certification

When a buy-sell agreement provides for corporate repurchase, the transaction constitutes a distribution governed by Cal. Corp. Code § 500. The corporation must satisfy one of two tests before repurchasing shares:

The board may base its determination on financial statements, fair valuation, or any reasonable method (Cal. Corp. Code § 500(c)). The statute does not specify whether a failed repurchase is void, voidable, deferred, or creates corporate debt.

Partnerships: Mandatory Statutory Buyout Procedures

For partnerships, the Uniform Partnership Act establishes a default mandatory buyout upon dissociation. When a partner dissociates and the business continues, the partnership must purchase the dissociated partner's interest at a price equal to what would be distributable if assets were sold at the greater of liquidation or going-concern value, plus interest (Cal. Corp. Code §§ 16701(a), (b)).

The partnership must provide detailed disclosures with any payment: a statement of assets and liabilities, the latest balance sheet and income statement, an explanation of the calculation, and notice that the payment satisfies the obligation unless the partner sues within 120 days (Cal. Corp. Code § 16701(g)). Enforcement actions must be commenced within 120 days after tender or one year after demand if no tender (Cal. Corp. Code § 16701(i)).

LLCs: Explicit Contractual Provisions Required

California's RULLCA provides no default buyout mechanism upon member dissociation outside judicial dissolution. Under Cal. Corp. Code § 17706.03, a dissociating member's interest converts to a transferee interest with economic rights but no governance rights—effectively locking capital in the entity unless the operating agreement provides otherwise or judicial dissolution is sought.

The statutory buyout mechanism of Cal. Corp. Code § 17707.03 applies only in judicial dissolution proceedings, where other members may purchase the moving parties' interests at fair market value to avoid dissolution.

Community Property Businesses: Spousal Notice and Consent

For businesses constituting community property, Cal. Family Code § 1100(d) requires the managing spouse to give prior written notice to the other spouse before any sale, lease, exchange, encumbrance, or disposition of "all or substantially all" of the business's personal property. We are not aware of any California case law defining this quantitative threshold.

Additionally, Cal. Family Code § 1100(b) prohibits any gift of community personal property or disposition for less than fair and reasonable value without the other spouse's written consent. Written consent is also required for transfers of the family dwelling, furniture, fittings, or clothing (Cal. Family Code § 1100(c)).

How is my business valued in a buy-sell agreement?

Your business can be valued in a buy-sell agreement using methods including book value, fair market value, agreed value, or formula methods. Private agreements can specify any method but must be definite enough for enforcement. If no agreement exists, statutory default standards apply in dissolution proceedings:

Both statutes provide default methodologies when parties have not agreed otherwise, mandate three disinterested appraisers with majority-award finality, and permit judicial adjustment of valuation dates for good cause.

What makes a buy-sell agreement unenforceable in California?

Retroactive Restrictions Without Shareholder Consent

Transfer restrictions adopted after shares are issued are unenforceable against pre-existing shareholders who did not vote in favor (Cal. Corp. Code § 204(b)).

Waivers of Mandatory Corporate Protections

Close corporation shareholders' agreements may not alter or waive mandatory Corporations Code provisions including transfer restriction rules (§§ 417, 418), distribution limitations (§ 500), and dissolution procedures (Cal. Corp. Code § 300(c)).

Unreasonable Restrictions on Alienation

Transfer restrictions that constitute an unreasonably restrictive curtailment of the right of alienation or unreasonably deprive shareholders of substantial rights are unenforceable. In Tu-Vu Drive-In Corp. v. Ashkins, 61 Cal.2d 283 (Cal. 1964), the California Supreme Court upheld a right-of-first-refusal provision as reasonable because it served legitimate purposes of preventing unwanted outsider intrusion and preserving entity integrity—while noting restrictions must be proportionate to shareholder rights.

Vague or Uncertain Terms

Agreement terms not sufficiently certain to make the precise act clearly ascertainable bar specific performance under Cal. Civil Code § 3390(e). This creates particular risk for valuation formulas that are incomplete, ambiguous, or fail to specify accounting standards, appraisal procedures, or adjustment methodologies.

When will a California court enforce a buy-sell agreement?

Consideration and Contract Formation

Standard contract formation requirements apply. For liquidated damages provisions, Cal. Civil Code § 1671(b) establishes a presumption of validity for commercial agreements unless the challenging party proves unreasonableness at the time of contracting—the stricter standard of § 1671(d) applies only to consumer retail and residential leases.

Specific Performance Requirements

California courts require five elements for specific performance: (1) valid, binding contract with sufficiently definite terms; (2) fair terms with adequate consideration; (3) plaintiff's performance or readiness to perform; (4) inadequacy of monetary damages; and (5) definite and certain terms permitting enforcement without continuous supervision.

Under Cal. Civil Code § 3386, specific performance may be compelled if the counterperformance has been substantially performed or its future performance is assured, even if the agreed counterperformance would not otherwise be specifically enforceable.

Categorical bars under Cal. Civil Code § 3390 include: personal service obligations; acts beyond the party's lawful power; agreements conditioned on third-party consent; and agreements with insufficiently certain terms.

How is California buy-sell agreement law different from other states?

No Default LLC Buyout Rights

Unlike many states and unlike California's partnership law, RULLCA provides no statutory buyout upon member dissociation outside judicial dissolution. This creates a fundamental drafting necessity: LLC operating agreements must explicitly establish buyout triggers, valuation methods, funding mechanisms, and payment terms.

Community Property Integration

California's community property system imposes spousal notice and consent requirements absent in common-law property states. The managing spouse must provide prior written notice before dispositions of "all or substantially all" community business property, and written consent is required for gifts or below-market transfers.

Close Corporation Partnership Substitutes

California's Cal. Corp. Code § 300(b) provides statutory validation for comprehensive shareholders' agreements that treat close corporations as partnership substitutes—including management arrangements, profit divisions, and liquidation distributions that would be impermissible in general corporations.

What are common mistakes in California buy-sell agreements?

Failure to Update Certificates of Agreed Value

Agreements requiring periodic valuation updates that are never executed undermine reliability for enforcement and estate planning. Inadequate documentation invites challenges to agreed pricing.

Ignoring Mandatory Share Certificate Legends

Omitting required § 418(a) or § 418(c) legends renders restrictions unenforceable against transferees lacking actual knowledge—potentially allowing unwanted third-party shareholders to acquire interests free of buy-sell obligations.

Missing Community Property Integration

Failure to obtain spousal consent for below-market transfers or to provide required notice for business dispositions creates post-transaction remedies under Cal. Family Code § 1101, including accounting, title addition, and monetary awards of 50% or 100% of affected assets plus attorney's fees.

Vague Pricing Formulas

Valuation provisions that fail to specify accounting standards (GAAP or otherwise), appraisal procedures, appraiser qualifications, or adjustment methodologies risk being deemed insufficiently certain for specific performance under Cal. Civil Code § 3390(e).

Insurance Funding Defects

Procuring life insurance without the insured's written consent voids the policy. Failing to secure insurable interest at policy inception (though it need not exist at loss) also voids coverage.

Corporate Repurchase Without Solvency Analysis

Repurchases that fail Cal. Corp. Code § 500 financial tests expose directors to liability. Because the statute does not specify the remedy for non-compliance, the transaction's validity and the corporation's obligations remain uncertain.

LLC Dissociation Without Contractual Buyout

Members who dissociate without a contractual buyout provision become transferees with no governance rights and no statutory liquidity mechanism—potentially locking capital indefinitely unless judicial dissolution is sought.

Because the enforceability of specific buy-sell provisions depends on your entity type, ownership structure, and the precise language of your agreement, Ask Sawyer researches California corporate, LLC, and partnership law to answer questions about your specific facts.
