New California Debt Collection Law: What SB 1286 Changes

California’s debt collection landscape shifted on July 1, 2025, when SB 1286 amended the Rosenthal Fair Debt Collection Practices Act. Under the state’s new debt collection law, protections that had applied only to consumer debts now extend to certain commercial debts as well. If you personally borrowed for business purposes, or you personally guaranteed a business loan, the same anti-harassment, disclosure, and dispute rules that consumers have relied on for decades now apply to you.¹

What SB 1286 Changed

Before July 2025, if you took out a personal loan to fund a small business or co-signed on your company’s credit line, the Rosenthal Act largely left you on your own when collectors called. SB 1286 closed that gap by adding “covered commercial debt” to the law.

A commercial debt qualifies for protection when three conditions are met:

The debtor is a natural person, not an LLC or corporation. This includes an individual who personally guaranteed a loan taken out in a business’s name.
The commercial credit transaction is valued at $500,000 or less.
The debt was entered into, renewed, sold, or assigned on or after July 1, 2025.

A sole proprietor who borrowed $80,000 for equipment, or someone who co-signed on a $200,000 business loan, now gets the same protections consumer debtors have.² One boundary: debts owed by business entities themselves, such as an LLC that took on debt without any personal guarantee, remain outside the law’s reach.

Who the Rosenthal Act Covers

The Rosenthal Act reaches further than its federal counterpart, the Fair Debt Collection Practices Act. Federal law regulates only third-party collectors. California’s law applies to anyone who regularly engages in debt collection, whether collecting their own accounts or someone else’s.³ So if a credit card company’s in-house collections team harasses you, federal law may not help, but the Rosenthal Act can.

The law also covers debt buyers, the companies that purchase delinquent accounts in bulk. California requires both debt collectors and debt buyers to hold a license from the Department of Financial Protection and Innovation.

On top of that, California Civil Code Section 1788.17 requires every debt collector pursuing a consumer debt to also comply with the key provisions of the federal FDCPA.⁴ California consumers get the protections of both statutes, with the stronger rule applying wherever the two overlap.

Disclosures Every Collector Must Give You

Every written or digital communication from a debt collector has to display the collector’s California license number in at least 12-point type. Collectors must also give you that number verbally if you ask.⁵ Checking that number against the DFPI’s online search tool is one of the quickest ways to tell a legitimate collector from a scammer.⁶

Under both state law and incorporated federal rules, a collector must send a written validation notice as their first communication or within five days of first contact. That notice has to include the name of the creditor, an itemized breakdown of the current debt amount reflecting interest, fees, and payments, and a clear statement of your right to dispute the debt within 30 days.⁷

For the newly covered commercial debts, SB 1286 adds notice requirements. Collectors must explain your right to request records showing their authorization to collect the debt, the balance including interest and fees, dates of delinquency, the creditor’s name and account number, and your last known address from the creditor’s records. If the original agreement was made in a language other than English, the collector must provide the notice in that language.

When Collectors Can Contact You

Debt collectors cannot call before 8 a.m. or after 9 p.m. unless you have given them permission.⁸ They also cannot call at times or places they know are inconvenient for you.

California law prohibits calling repeatedly or continuously to annoy you, and bars contacting you with a frequency that amounts to harassment.⁵ There is no magic number that crosses the line. Courts look at the pattern and context. If your phone rings five times a day from the same collector, the pattern speaks for itself.

Tactics That Are Off Limits

The Rosenthal Act bars a range of deceptive and abusive practices. A debt collector cannot:

Communicate under any name other than the collection agency’s or the creditor’s.
Falsely represent that they are a lawyer, or send correspondence on an attorney’s letterhead without that attorney’s approval.
Claim to be affiliated with or acting on behalf of a government agency unless they actually are.
Trick you into accepting a call or incurring long-distance charges by lying about the purpose of the call.

These restrictions apply to the collection of any covered debt, including the commercial debts brought under the law by SB 1286.⁹

Disputing a Debt

If a validation notice arrives and you believe the debt is wrong, you have 30 days to dispute it in writing. Once you send that dispute, the collector must pause all collection activity on the disputed amount until they provide adequate verification.⁷ Adequate verification means actual documentation, not a restatement of the same claim.

For commercial debts under SB 1286, collectors face an additional duty. If you submit a written request for information, they must produce proof of their authority to collect, a balance breakdown, delinquency dates, the creditor’s name and account number, and their California license number within 30 calendar days. If they cannot produce that information on time, all collection activity must stop until they can.

What a Violation Is Worth

A debt collector who violates the Rosenthal Act is liable for the actual damages you suffered. If the violation was willful and knowing, a court can add a statutory penalty between $100 and $1,000.¹⁰ The real financial exposure for collectors comes from attorney fees. A prevailing debtor is entitled to reasonable attorney fees and court costs, which often dwarf the statutory penalty. Because Section 1788.17 also incorporates the federal FDCPA, a collector may face liability under both laws, and the federal statute allows up to $1,000 in additional statutory damages per individual action.¹¹

One important limit: Rosenthal Act claims must be brought individually. You cannot pool your claim with other consumers who were mistreated by the same collector.

The 15-Day Cure Window

Collectors get one chance to avoid liability. If a collector discovers a violation or receives your written notice of one, they have 15 days to notify you and correct the problem. If they fix it within that window, civil liability disappears. A collector can also escape liability by showing the violation was unintentional and that they maintained reasonable procedures to prevent it. That is why a well-drafted letter identifying the specific violation and citing the statute often produces a correction inside 15 days without any lawsuit at all.

How to File a Complaint

You have two paths when a collector breaks the rules: a private lawsuit under the Rosenthal Act, and a regulatory complaint with the DFPI. You can pursue both at the same time.

The fastest way to file with the DFPI is the online complaint form on the department’s website, which takes about five minutes. You can also download the form and mail it to the Consumer Services office at 651 Bannon Street, Suite 300, Sacramento, CA 95811. For help completing the form, call 1-866-275-2677.¹²

For a private lawsuit, the attorney fee provision means many consumer attorneys will take Rosenthal Act cases on contingency. Document everything from the start. Save voicemails, screenshot text messages, keep envelopes showing postmark dates, and write down the date, time, and substance of every phone call. Solid records are what turn a claim into a quick settlement instead of a stalled one.
