Successor Liability in California: When a New Company Inherits the Old One's Debts

Last updated: November 2026. Reviewed by Pavel Kolmogorov, California business litigation attorney (State Bar No. 321018).

Successor liability is the rule that decides when a company that takes over another's business also takes on its debts. A California asset buyer normally does not. There are four exceptions: it agreed to assume the debts, the deal was in substance a merger, the new company is a mere continuation of the old one, or the transfer was made to escape them. (Ray v. Alad Corp. (1977) 19 Cal.3d 22, 28.) Kolmogorov Law, P.C. litigates these claims in Orange County, Los Angeles, and statewide.

The general rule of successor liability and its four exceptions

Start with the default. A company that buys the principal assets of another does not assume the seller's liabilities. The California Supreme Court lists four exceptions. The first two are an express or implied agreement to assume the liabilities and a transaction that amounts to a consolidation or merger. The others are a purchaser that is a mere continuation of the seller and a transfer made for the fraudulent purpose of escaping the seller's debts. (Ray, supra, 19 Cal.3d at p. 28.)

A true statutory merger is different. There the surviving corporation is subject to all debts and liabilities of the disappearing one, as if it had incurred them itself. (Corp. Code, § 1107, subd. (a).)

Ray then went on to recognize a separate exception for strict tort liability over defective products when the buyer continues the same product line. (Ray, supra, 19 Cal.3d at p. 34.) The court declined to change the general rule for other liabilities. (Id. at p. 30.) A contract creditor cannot rely on the product line exception, and it is outside the commercial debts this page covers.

Mere continuation: same business, new name

The pattern is familiar. A company falls behind with a supplier or sees a lawsuit coming. A new LLC appears. The trucks, the crew, the phone number, and the customers move over a weekend, and the old company is left with its debts and little else.

California decisions have imposed liability on a mere continuation only on a showing of one or both of two facts. One: no adequate consideration was given for the old company's assets and made available to meet the claims of its unsecured creditors. Two: one or more persons were officers, directors, or stockholders of both companies. (Ray, supra, 19 Cal.3d at p. 29.)

Courts do not agree on whether inadequate consideration is indispensable. Some Court of Appeal decisions call it essential. Another declined to require it in every case, and stressed that successor liability is an equitable doctrine examined on each case's own facts. (Cleveland v. Johnson (2012) 209 Cal.App.4th 1315, 1330, 1333-1334.)

In practice the two facts tend to travel together. An owner selling to himself rarely pays full price, and what he pays rarely reaches creditors.

Transfers made to escape the seller's debts

The fourth exception turns on purpose. If assets were moved to a new entity to get out from under a debt, the new entity can be held liable for it. In Cleveland, evidence that the owner shifted a line of business into a new corporation and hid it from the plaintiff supported liability on this ground too. (Cleveland, supra, 209 Cal.App.4th at p. 1334.)

Timing is often the strongest evidence. A new entity formed the month after a demand letter, or while a lawsuit was pending, invites the inference.

This exception overlaps with the Uniform Voidable Transactions Act, but the remedies differ. A voidable transfer claim is generally aimed at the asset or its value. Successor liability makes the new company answerable for the debt itself. We often plead both, and our fraudulent transfers page explains the statute. Where the owner treated both companies as a personal wallet, alter ego is a third route, aimed at the owner personally.

Assumed liabilities and de facto mergers

The first two exceptions usually come from the deal documents.

An asset purchase agreement normally lists assumed and excluded liabilities. If your claim is on the assumed list, the analysis is short. The agreement to assume can also be implied, and that turns on the facts.

A de facto merger is an asset sale that works like a merger. The Supreme Court has described two settings. In one, the buyer takes all the assets without giving consideration that could be made available to the seller's creditors. In the other, the price is paid wholly in the buyer's stock, which goes promptly to the seller's shareholders as the seller liquidates. (Ray, supra, 19 Cal.3d at pp. 28-29.)

If you sold a business and the buyer has not paid you, that is a different dispute, covered on our page about breach of a business purchase agreement.

If you are the creditor

Name the new company as a defendant at the outset when the facts support it.

Gather what shows continuity: the same address, phone number, website, and a similar trade name; the same managers and employees; the same customers, equipment, and licenses. Pull the Secretary of State filings to see who formed the new entity and when.

Then look at consideration, which is the first thing I ask about. Was there a written sale? What was paid, and where did the money go?

If the old company filed dissolution papers, its former owners may also be reachable up to what they received. Our page on suing a dissolved corporation or LLC explains that claim and its deadline.

If you bought the assets

A buyer who paid fair value at arm's length, to the selling company, with no overlap in ownership, is in the position the general rule protects.

Buyers get into trouble at the edges. The price went to the owner personally instead of the company. The seller's principal stayed on with equity in the buyer. The marketing told customers nothing had changed. The purchase closed while everyone knew a judgment was coming. No single fact decides the case, but together they give a creditor a story to tell.

What to bring to the first meeting

Creditors should bring the contract, invoices, or judgment that establishes the debt, plus anything showing the move: old and new websites, letterhead, emails from the same people under a new name, and public filings for both entities. Buyers should bring the purchase agreement, proof of payment, any appraisal, and the creditor's demand or complaint.

Frequently asked questions

The business that owes us closed and reopened under a new name at the same address with the same owner. Can we sue the new company?

Often, yes. California courts have applied the mere continuation exception on a showing that the two companies share owners, officers, or directors, or that the assets moved without adequate consideration available to creditors. Same owner, same address, and same customers are the facts to document, although no single fact decides the question. You would typically sue both companies and consider a voidable transfer claim alongside.

What is successor liability in California?

Successor liability is the doctrine that determines when a company acquiring another's assets is also responsible for its debts. The California Supreme Court's rule in Ray v. Alad Corp. is that the purchaser is not liable unless it assumed the liabilities, the deal amounted to a merger, the purchaser merely continues the seller, or the transfer was a fraudulent attempt to escape debts.

I bought the equipment and customer list of a company that was being sued. Am I responsible for its debts now?

Not automatically. Under California law an asset purchaser generally does not take on the seller's liabilities. The risk rises if you agreed to assume them, paid less than fair value, share owners or officers with the seller, or bought to help the seller avoid a creditor. Keep the purchase agreement, proof of payment to the selling company, and any valuation.

Does an asset purchase protect the buyer from the seller's liabilities?

Usually, but not in every case. California starts from the rule that buying assets, unlike a statutory merger, does not transfer the seller's debts. Four exceptions can override the structure: assumption by agreement, a de facto merger, a mere continuation, and a transfer made for the fraudulent purpose of escaping liability. Courts treat the question as equitable and fact-specific.

What is the mere continuation exception to successor liability?

It applies when the buyer is really the seller under a new name. California decisions have required one or both of two showings: the assets changed hands without adequate consideration available to the seller's unsecured creditors, or the two companies shared officers, directors, or stockholders. Appellate courts differ on whether inadequate consideration must be present every time.
