Ask the dealer in writing for every contract version and the signing record behind each signature you dispute; an electronic signature is attributable to you only if it was your act. Charges may not be added without full disclosure and your consent, and California’s Attorney General sends motor-dealer complaints to the DMV Division of Investigations.

Compare the versions before arguing about the outcome

Make a separate row for each document, including the maintenance agreement you received at the sale and the replacement the dealership later produced. Keep the original files intact. Use copies for highlighting and comparison. This worksheet is an organizational aid, not proof that a document is forged.

Section 1633.9 addresses electronic records and signatures; if a disputed signature is handwritten, note that separately and raise it with counsel.

A signature image and authorization are different questions

Under California Civil Code section 1633.9, where the electronic-transactions law applies, an electronic record or signature is attributable to a person if it was that person’s act. The act can be shown in different ways, including an applied security procedure. Ask the dealer to identify what supports its assertion that you authorized the disputed version.

The same statute treats the effect of an attributed record as a context question, including the circumstances of creation, execution or adoption and the parties’ agreement. Separate “who signed?” from “what did that signing agree to?” A completion record can be useful evidence to request, but this guide does not assume every platform collects the same information.

Use a factual description such as “I dispute authorizing this version” unless you have a basis for a stronger allegation. Our electronic-signature guide can help organize the format question. Keep the attribution dispute tied to the actual transaction records.

Identify every signature, initial or approval entry you dispute.
Request the corresponding signing record and document version from the dealer.
Ask how the dealer attributes that act to you, rather than accepting the image alone.
Record what you recall reviewing and receiving, alongside the surrounding messages.

Separate the maintenance promise from the price and financing

The California Attorney General’s buyer guidance says charges may not be added without full disclosure and consent. It also describes an itemized price list for optional add-ons such as service contracts. Compare that list, your financing itemization and the actual plan agreement.

For a conditional sale contract covered by the Automobile Sales Finance Act, Civil Code section 2982 includes disclosure of the amount charged for a service contract, as applicable. Ask counsel to select the applicable statutory version for your transaction date.

Do not assume a maintenance package, a manufacturer’s warranty and a separately sold service contract are the same document. Ask the dealer and provider to identify the product they say you bought, its covered services and the basis for any replacement. Use the documents’ own names in your dispute.

An illustrative maintenance-plan discrepancy

Your retained agreement lists scheduled services, while the later version identifies a different package. The financing amount might be unchanged even though the promised services differ. Mark both the benefit difference and any price difference. If you challenge an added charge, California’s disclosure-and-consent guidance is relevant. If you challenge missing services instead, state that issue separately.

Ask the provider which version it received and whether it recorded any later instruction. Preserve the response. Do not label the original agreement canceled merely because another version appeared in the dealer’s records.

Can a written agreement change after signing?

Yes. California Civil Code section 1698 permits modification by a written contract. It also recognizes oral modification to the extent the parties execute it. Unless the contract expressly provides otherwise, an oral modification supported by new consideration may be permitted.

If the modified contract falls within the statute of frauds, the statutory writing requirements must also be satisfied. Have counsel review the applicable formalities and modification clause. If the dealer relies on an oral approval, ask it to identify the agreement, the performance by both parties it relies on, and any new consideration. Check whether your contract expressly limits changes to a signed writing.

For a dealer’s claimed oral approval, write down the exact conversation you dispute, when it allegedly occurred, who participated and what performance followed. Our contract amendment guide can help organize the original clause and the proposed change for review. Keep an oral-promise issue separate from a signature-attribution issue.

Send a factual evidence request, then review the legal notice

Ask for the versions the dealership relies on rather than demanding that it immediately concede fraud. Request the original deal documents, disputed replacements, any claimed authorization, the version supplied to the lender and the version supplied to the plan provider. Save your request and all responses. This request is a practical evidence aid; it does not represent that a particular statute entitles you to every requested internal record.

A formal damages claim under the Consumers Legal Remedies Act has a different notice rule. Civil Code section 1782 calls for notice thirty days or more before starting that damages action. It requires notice of the particular alleged violations and a demand to rectify the goods or services.

The written notice must use certified or registered mail, return receipt requested, to the transaction location or the person’s principal place of business within California. Have counsel prepare it for the particular claims. Do not treat an ordinary records-request email as automatically satisfying that procedure.

The statute separately permits an injunctive-relief action without compliance with that pre-action subdivision. That distinction is a reason to review the desired remedy with counsel, not a general instruction to delay every kind of legal action.

Sample document-dispute request for counsel to adapt

Re: [vehicle and transaction identifier]. I dispute authorizing the [document title and version/date] you supplied on [date]. My retained agreement is [identifier]. The discrepancies are [pages, signature entries, price or covered services]. Please identify the version you consider operative and provide the documents and authorization records supporting that position, including the versions supplied to the lender and plan provider. Please preserve the relevant records and explain any claimed change to my original maintenance agreement. I am requesting records and an explanation, not agreeing to replacement terms.

Choose the agency that matches the problem

California’s Attorney General directs motor-dealer disputes to the DMV Division of Investigations. The DMV complaint instructions identify the Record of Complaint Form, INV 172A. Attach photocopies, not originals, and submit the form in person, by fax or by mail to your local DMV Investigations office.

A DMV investigation is not a monetary-award process. Keep your regulatory complaint and request for private relief distinct. A submitted complaint does not prove the signature allegation.

The Bureau of Automotive Repair handles general automotive repair and service complaints. It handles new or used vehicle-sale complaints only when repairs were part of the sale. Filing a BAR complaint does not automatically establish a law violation.

The Attorney General also directs vehicle-service-contract questions to the California Department of Insurance. Ask which product and regulator apply to your particular maintenance agreement, rather than assuming every plan has the same cancellation or refund rules.

Review possible remedies without assuming a guaranteed result

Civil Code section 1770(a)(14) prohibits specified misrepresentations about a transaction’s rights, remedies or obligations. Business and Professions Code section 17200 includes unlawful, unfair or fraudulent business acts within unfair competition. Those provisions are potential review questions, not a finding that your dealer violated them.

For the writing itself, Civil Code section 3399 addresses revision when fraud or the specified mistake means a written contract does not express the parties’ intention. It also protects rights third persons acquired in good faith and for value. A lender’s involvement is therefore a reason to identify all the documents and parties, rather than assume only the dealer’s copy matters.

Civil Code section 1689 lists rescission grounds, including consent obtained through fraud, duress or other specified circumstances. Ask counsel whether your evidence supports revision, rescission, a damages theory or a negotiated correction. Do not assume that a disputed signature automatically cancels every agreement connected with the sale.

Take a clear version dispute to counsel

Bring every version; label the differences; identify the signatures you dispute; separate the maintenance benefit from any financed charge; collect the lender and provider responses; and ask for review of the applicable law, contract procedures and deadlines. Use the contract review checklist to locate notices, dispute clauses and the agreement’s change provisions.

If the dealer demands the car back or threatens collection, ask for the basis in writing and get prompt advice from a California lawyer. The financing notice required by current section 2982 warns that default may lead to repossession. Do not assume a records complaint itself changes payment obligations or resolves a return demand.

Frequently asked questions

Does a signature image prove I agreed to the replacement contract?

Not by itself as an attribution analysis. California’s electronic-transactions statute asks whether the record or signature was your act and recognizes evidence such as an applied security procedure. The effect of an attributed signature also depends on context and the agreement.

Can the dealer add a maintenance-plan charge without consent?

California’s Attorney General says charges may not be added without full disclosure and consent. Compare the price disclosures and agreement you received with the later version, then identify the particular charge you dispute.

Can a verbal agreement change a written contract in California?

Sometimes. Section 1698 recognizes an oral agreement to the extent executed by the parties, and certain oral modifications supported by new consideration unless expressly barred by the contract. Writing requirements may still apply.

Can I sue a dealership for lying about repairs?

A California lawyer can assess the representation and supporting evidence. The CLRA includes specified misrepresentations about transaction rights or obligations. BAR handles repair and service complaints within its scope, but a complaint does not automatically establish a violation.

Can the dealership take the car back after I signed?

If the dealer demands the car back, ask for its stated basis in writing and have a California lawyer review the contract; the required 2982 financing notice addresses repossession after default.

Will a DMV complaint get my money back?

A DMV investigation is not a monetary-award procedure. Discuss a separate civil remedy with counsel while preserving the complaint evidence.

Is my evidence-request email the formal CLRA notice?

Do not assume so. Section 1782 prescribes timing, content and certified or registered mail with return receipt requested for a CLRA damages-action notice. Have counsel check compliance for the claim you intend to bring.
