Personal Guaranty After a Loan Default in California

The short answer

If you signed a personal guaranty of a commercial real estate loan and the loan is now in default, assume the following until a lawyer reads your documents:

• The lender does not have to foreclose first. The one-action rule protects the borrower, not the guarantor, and a guaranty can also waive any right to make the lender go after the property first. (Union Bank v. Gradsky (1968) 265 Cal.App.2d 40, 43, fn. 3; Civ. Code, § 2856, subds. (a)(3), (c)(1).)
• The antideficiency statutes mostly do not help you. Code of Civil Procedure sections 580b and 580d each say expressly that they do not affect the liability a guarantor "might otherwise have." (§ 580b, subd. (c); § 580d, subd. (b).)
• Your guaranty may well have waived the main defense that remains, the Gradsky defense, along with most of the suretyship rights in Civil Code sections 2787 through 2855. Section 2856 makes those waivers enforceable without magic words.
• The real decisions are practical: what to sign, whether to buy the loan or bid at the sale, how to structure a workout so the guaranty is actually released, and whether your facts support a defense the waivers cannot reach.

The weeks after the default can matter more than anything you do after a judgment.

Lenders are moving. On November 9, 2026, the Los Angeles Business Journal ran the headlines "Scoop: Lenders Set Foreclosure Auction for Radford Studio Center" and "Godfrey Hotel Hits Default." We know nothing about those deals beyond the headlines, and nothing here suggests either involves a guaranty. They are a sign of the climate. For owners, sponsors and LLC members who guaranteed their own building loans, the question is personal.

What might my guaranty have waived?

California treats a guarantor as a surety. Civil Code section 2787 says: "The distinction between sureties and guarantors is hereby abolished." That matters because the Civil Code gives sureties a set of default protections, and a commercial guaranty is often drafted to give nearly all of them up.

The default protections

Without a waiver, a guarantor has rights such as these:

• No greater liability than the borrower. A surety's obligation "must be neither larger in amount nor in other respects more burdensome than that of the principal." (§ 2809.)
• Exoneration if the deal changes without consent. A surety is exonerated if, by any act of the creditor, "without the consent of the surety the original obligation of the principal is altered in any respect," or the creditor's remedies against the borrower are impaired or suspended. (§ 2819.)
• Make the lender go after the borrower first. A surety may require the creditor "to proceed against the principal," and is exonerated to the extent prejudiced if the creditor neglects to do so. (§ 2845.)
• The benefit of the lender's security. A surety "is entitled to the benefit of every security for the performance of the principal obligation held by the creditor." (§ 2849.) If the surety's own property is pledged along with the borrower's, the borrower's property is applied first. (§ 2850.)

What section 2856 lets the lender take away

Civil Code section 2856, subdivision (a), lets any guarantor, "including a guarantor of a note or other obligation secured by real property," waive three categories:

1. Suretyship rights. Subrogation, reimbursement, indemnification and contribution, and any other rights or defenses available under sections 2787 to 2855. (§ 2856, subd. (a)(1).) That reaches sections 2809, 2819, 2845, 2849 and 2850.
2. Election-of-remedies defenses. Any rights or defenses arising from the creditor's election of remedies. (§ 2856, subd. (a)(2).)
3. Real-property defenses. Any rights or defenses arising because the borrower's obligation is secured by real property, including those based on Code of Civil Procedure sections 580a, 580b, 580d or 726. (§ 2856, subd. (a)(3).)

A waiver is effective "without regard to the inclusion of any particular language or phrases" or any reference to statutes or cases. (§ 2856, subd. (b).) Subdivisions (c) and (d) then supply model paragraphs that are deemed effective. The subdivision (c) paragraph tells the guarantor that "The creditor may collect from the guarantor without first foreclosing on any real or personal property collateral pledged by the debtor," and that after a foreclosure, "The amount of the debt may be reduced only by the price for which that collateral is sold at the foreclosure sale, even if the collateral is worth more than the sale price." If your guaranty contains language close to that, assume you signed it.

There is one exclusion. Subdivisions (b), (c) and (d) do not apply to a guaranty of a purchase-money loan on a dwelling of four or fewer units occupied by the borrower. (§ 2856, subd. (e).) That rarely describes a commercial building loan. Waivers signed before January 1, 1997 are judged under the law in effect when they were signed. (§ 2856, subd. (f).)

The Gradsky defense, and how it is waived

Under Code of Civil Procedure section 580d, subdivision (a), no deficiency is owed on a note secured by real property after a trustee's sale under a power of sale. That protects the borrower. In Union Bank v. Gradsky (1968) 265 Cal.App.2d 40, the Court of Appeal held that a lender that forecloses nonjudicially also loses its claim against the guarantor, because the sale destroys the guarantor's right to be reimbursed by the borrower: "We hold that the creditor cannot recover from the guarantor the unpaid balance upon the note following the creditor's nonjudicial sale of the security." (Id. at p. 41.) The bar rested on estoppel, not on section 580d itself.

Gradsky allowed waiver by express contract or later conduct, but absent an explicit waiver would not strain the guaranty to find one by implication. (Id. at p. 48.) In Cathay Bank v. Lee (1993) 14 Cal.App.4th 1533, the court found a bank's form waiver insufficient. The Legislature then enacted section 2856, which the Court of Appeal called an "apparent response" to Cathay. (River Bank America v. Diller (1995) 38 Cal.App.4th 1400, 1418.) Subdivision (d) now provides a model waiver of defenses arising from an election of remedies "such as a nonjudicial foreclosure." For a guaranty governed by section 2856, do not rely on Cathay's strict standard.

Section 580d, subdivision (b), provides that the bar on a deficiency "does not affect the liability that a guarantor, pledgor, or other surety might otherwise have with respect to the deficiency." Note the word "otherwise": the subdivision preserves whatever liability the guaranty creates, but it is not itself a waiver of the Gradsky defense. Section 580b, subdivision (c), contains the same carve-out for the purchase-money rules. As the Court of Appeal put it in LSREF2 Clover Property 4, LLC v. Festival Retail Fund 1, LP (2016) 3 Cal.App.5th 1067, 1075: "The antideficiency statutes' protections generally do not extend to guarantors."

Can the lender sue me before it forecloses?

Generally, yes. Code of Civil Procedure section 726, subdivision (a), says "There can be but one form of action for the recovery of any debt or the enforcement of any right secured by mortgage upon real property or an estate for years therein." That one-action rule protects the borrower. It does not protect a guarantor. In Gradsky, the court stated that "The one-action rule (Code Civ. Proc., § 726) is inapplicable to a suit by a secured creditor against a guarantor, endorser or other surety." (265 Cal.App.2d at p. 43, fn. 3.) The Gradsky defense discussed above arises only after a nonjudicial sale; it does not stop a suit on the guaranty before the lender resorts to the security. (Id. at p. 44.) A guaranty can also waive the section 2845 right to make the lender go after the borrower first; the Gradsky guaranty did. (Id. at p. 43, fn. 3.)

In practice, a lender holding a defaulted building loan and a solvent guarantor has several paths, and it can combine them:

1. Sue on the guaranty immediately, either alone or by joining you in a judicial foreclosure. Gradsky listed both options. (265 Cal.App.2d at p. 43.)
2. Record a notice of default and sell by trustee's sale, then sue you for the shortfall. With the section 2856 waivers in place, the Gradsky defense is gone and the debt is credited only with the sale price. Our article on the notice of default and cure period covers the minimum timeline.
3. Foreclose judicially and seek a deficiency, a route Cathay Bank v. Lee called "relatively cumbersome" (14 Cal.App.4th at p. 1535) and that our judicial vs. nonjudicial article compares.
4. Take the rents first by enforcing its assignment of rents or asking for a receiver, which does not by itself count as the one action. (Civ. Code, § 2938, subds. (c), (e)(2); Code Civ. Proc., § 564, subd. (d).) See our article on assignment of rents and receivers.

One procedural point helps guarantors. An arbitration award against the borrower alone "shall not be, be deemed to be, or be utilized as, an award against his surety." (Civ. Code, § 2855.) A lender that wants your liability decided has to bring you in.

Sham guaranty, briefly

A guaranty signed by someone who is really the borrower adds nothing, and the antideficiency statutes then apply with full force. (River Bank, supra, 38 Cal.App.4th at p. 1420.) Later published decisions have applied that defense narrowly. Courts look at whether there is "adequate legal separation between the borrower and the guarantor," and whether the lender structured the deal to put the real obligor in the guarantor's seat. (LSREF2, supra, 3 Cal.App.5th at p. 1075, quoting CADC/RADC Venture 2011-1 LLC v. Bradley (2015) 235 Cal.App.4th 775, 787.) If you chose the single-purpose LLC to limit your liability, LSREF2 answered with California Bank & Trust v. Lawlor (2013) 222 Cal.App.4th 625, 639: "Individuals may structure their own business dealings to limit their personal liability, but they must accept the risks that accompany the benefits of incorporation." It turns on the facts, not on the waiver clause.

What deadlines matter after the trustee's sale?

The borrower's three-month rule. After a trustee's sale, an action for the balance due on the secured obligation "must be brought within three months of the time of sale," and recovery is capped at the debt minus the property's fair market value. (Code Civ. Proc., § 580a.) Section 337, subdivision (a), has a parallel proviso that such an action "shall not extend beyond three months after the time of sale." The clock starts on the date of the trustee's sale.

Do not assume those limits protect you. Two published decisions hold that section 580a does not apply to a true guarantor. (Mariners Sav. & Loan Assn. v. Neil (1971) 22 Cal.App.3d 232, 234; Talbott v. Hustwit (2008) 164 Cal.App.4th 148.) Mariners relied on Bank of America etc. Assn. v. Hunter (1937) 8 Cal.2d 592, where the California Supreme Court held that the section 337 three-month proviso has no application to an action on a guarantor's independent obligation. (Id. at pp. 597-598.) Talbott reached the same result, though a concurring justice criticized the rule. Our judicial vs. nonjudicial foreclosure article leaves fair value for guarantors open; on the cases above, a guarantor should not count on either the fair value cap or the three-month window. Your guaranty may have waived section 580a anyway. (§ 2856, subd. (a)(3).)

The general limitations period. A suit on a written guaranty generally falls under the four-year period for an obligation founded on a writing. (Code Civ. Proc., § 337, subd. (a).) When it starts depends on the guaranty's terms, such as whether liability arises on default or on demand. Partial payments can matter under section 360, which section 337, subdivision (d), cross-references. The six-year period for promissory notes discussed in our article on the six-year rule for promissory notes governs a negotiable note payable at a definite time, and a separate guaranty is not automatically carried along.

The sale date itself. Anything you want to do about the property, including buying the loan or lining up a bidder, has to happen before the trustee's sale.

What can a guarantor actually do now?

1. Collect every document you signed

Get the guaranty, loan agreement, note, any environmental indemnity, and every later modification, forbearance or reaffirmation. Identify the type: full payment, a capped amount (in LSREF2 the guaranty covered $1.5 million of a $25,025,000 loan), or a nonrecourse carve-out guaranty. The cap and the trigger define your exposure more than any statute does.

2. Read before you sign anything new

Lenders working out a loan may ask the guarantor to sign a forbearance, modification or reaffirmation. Section 2819's exoneration applies to changes made "without the consent of the surety," and many guaranties waive it in advance. A new document can add releases, waivers or collateral. Treat it as a renegotiation of your guaranty.

3. Consider buying the loan or taking an assignment

A guarantor who pays is entitled to the benefit of the lender's security under section 2849, subject to any waiver of subrogation. Buying the note and deed of trust before the sale can put you in control of the foreclosure instead of on the receiving end of a deficiency claim. Turning down that kind of offer can hurt: in Mariners, the guarantor lost the Gradsky defense based on his explicit waivers and on his refusal, before the trustee's sale, of an offered assignment of the note and deed of trust conditioned on his paying the guaranty. (22 Cal.App.3d at pp. 236-237.)

4. Think about the sale price

Under the subdivision (c) language, the debt is reduced only by the sale price, so a low credit bid by the lender increases your deficiency. Bringing a bidder to the sale, or bidding yourself, may cost less than the deficiency.

5. Get the release in writing

A discounted payoff, deed in lieu or consensual sale deals with the loan. Any such agreement should also state expressly what happens to your guaranty and to any other guarantor.

6. Look for the defenses waivers cannot reach

Waivers do not save a guaranty that is a sham. Disputes about the amount owed, whether the plaintiff actually holds the guaranty, and whether a contractual trigger occurred are not among the categories section 2856 lists, although your guaranty may address some of them separately. If the foreclosure itself was defective, see our article on wrongful foreclosure and the tender rule.

Carve-out guaranties

Some larger loans are nonrecourse to the borrower, with a guaranty that springs into full recourse only if something specific happens. We found little published California appellate authority on these "bad boy" guaranties. The leading published case we found is GECCMC 2005-C1 Plummer Street Office Limited Partnership v. NRFC NNN Holdings, LLC (2012) 204 Cal.App.4th 998. The guaranty made a $44 million nonrecourse loan "fully recourse to Guarantor" if a lease was terminated without the lender's consent. The tenant stopped paying and left, but the court held the leases had not terminated, so the guaranty was never triggered, and it reversed a judgment of roughly $42.2 million. The court described the structure this way: "Thus, both the borrower and the guarantor are liable only if the borrower engages in the specified bad acts." (Id. at p. 1002.)

The trigger language controls. We have not found a published California decision construing a trigger based on a bankruptcy filing, an unpermitted transfer or a new lien. Read the carve-out list before taking any step it might cover.

Our contract disputes practice handles guaranty enforcement and defense, including the written-contract issues these cases turn on.
