Online Marketplace Liability Philippines: When Are Platforms Responsible?

Last correction: 18 October 2026. CyberCode updated the marketplace-liability tests, evidence checklist and complaint route after checking Republic Act No. 11967, especially Sections 3, 20–28, and the DTI implementing materials. This was a focused review of marketplace responsibility and consumer escalation; it was not a full review of payment-provider, criminal-fraud or data-privacy remedies.

Who is responsible first?

Situation	Likely starting point	When platform liability becomes a real issue	Evidence to keep
The item is defective, not as described, incomplete or never delivered	The online merchant or e-retailer is ordinarily primarily liable under Section 25	If the platform is the same entity as the merchant, or a Section 26 or 27 condition is supported by the facts	Order page, listing, seller identity, receipt, delivery record, photos or video, messages and refund request
The platform did not follow merchant-verification, listing, privacy or redress duties	Complain to the merchant and platform	Section 26 may apply if the failure to exercise ordinary diligence under Sections 21 or 22 caused the consumer’s loss or damage	Missing seller details, inaccurate listing fields, unanswered tickets, screenshots and a clear timeline connecting the failure to the loss
The foreign seller has no legal presence in the Philippines	Use the platform’s redress channel and request usable seller contact details	Section 26 may apply if the platform fails, despite notice, to provide the foreign merchant’s contact details	Your dated request, ticket ID, platform response and the seller profile or listing
The listing infringes intellectual-property rights or is covered by a government takedown order	Notify the platform with specific supporting material	Section 26 may apply if the platform fails after notice to act expeditiously to remove or disable access	Notice, rights or order relied on, exact listing URL, screenshots and whether the listing remained accessible
The goods or services are prohibited by law, imminently injurious, unsafe or dangerous	Notify the platform promptly; use the appropriate safety or enforcement route when urgent	Section 27 may impose solidary liability if the platform fails after notice to act expeditiously to remove or disable access	Product page, warning or test evidence, injury or hazard records, notice and post-notice availability

The three liability rules under RA 11967

1. The seller is ordinarily primarily liable

Section 25 places primary responsibility on the e-retailer or online merchant for indemnifying the online consumer in a civil action or administrative complaint arising from the transaction. For an ordinary defective-item or non-delivery dispute, that is why the seller is normally the first party asked to repair, replace or refund.

There is an important exception: if the marketplace or platform and the online merchant are found to be the same entity, the law treats their liability as one and the same. Labels in terms and conditions are relevant, but the actual transaction structure may also matter.

2. A platform can be subsidiarily liable in three situations

Section 26 identifies three routes to subsidiary liability:

• The platform failed to exercise ordinary diligence in meeting its obligations under Sections 21 or 22, and that failure resulted in the consumer’s loss or damage.
• After notice, the platform failed to act expeditiously to remove or disable access to goods or services that infringe intellectual-property rights or are subject to a takedown order from an appropriate government agency.
• The merchant has no legal presence in the Philippines, and the platform failed, despite notice, to provide the merchant’s contact details.

The statute limits this subsidiary liability to damages directly resulting from the transaction. It also protects a platform that relied in good faith on a merchant’s representations or documents if the platform can show good faith and reasonable efforts to check and maintain their accuracy, authenticity and veracity. A seller’s false document therefore does not, by itself, prove that the platform is liable.

3. A platform can be solidarily liable for prohibited or dangerous offerings

Section 27 uses a stronger rule for goods or services that are prohibited by law, imminently injurious, unsafe or dangerous. A marketplace or digital platform may be solidarily liable when, after notice, it fails to act expeditiously to remove the offering or disable access to it. “Solidary” does not mean every unsafe listing automatically makes the platform pay; the statutory conditions—including notice and failure to act expeditiously—still need evidence.

What duties can matter under Sections 21 and 22?

An e-marketplace that retains oversight over the transaction must, among other things, make the transaction and the responsible merchant identifiable; require specified identity, address and contact information from merchants as far as practicable; maintain and regularly verify a merchant list; take privacy and information-security precautions; address regulated goods; provide an effective and responsive redress mechanism; and require essential offer details such as the name, brand, price, description and condition.

Other digital platforms that do not retain oversight over consummation of the transaction have a different but related set of Section 22 duties. These include helping consumers distinguish commercial from private accounts, requiring essential listing and contact information, providing a redress mechanism, maintaining merchant-account information as far as practicable, and observing privacy and information-security duties.

The distinction matters because RA 11967 does not treat every website, app or social platform as performing the same role. The Act also excludes consumer-to-consumer transactions from its coverage. A person who regularly sells in the ordinary course of business, however, is not necessarily a private C2C seller merely because the sale took place through a social-media account.

Evidence first: build the record before the listing or chat disappears

Keep copies outside the marketplace app. Record what you could see on the date of purchase and what changed later. For a fuller preservation list, use the online scam evidence checklist.

Action: complain in the right order

1. Identify the transaction and both parties. State the order number, seller, platform and date. Do not describe the marketplace as the seller unless the record supports that conclusion.
2. Ask for a specific remedy. Depending on the problem, request repair, replacement, refund, delivery, correction, seller contact details, or removal of a dangerous or unlawful listing. See the guide to e-commerce returns and refunds for remedy selection.
3. Open the platform’s internal case. Section 24 requires an aggrieved party to use the internal redress mechanism before filing a complaint with a court, government agency or alternative-dispute-resolution forum. The mechanism is deemed exhausted if the complaint remains unresolved after seven calendar days.
4. State the platform issue separately. If you rely on Section 26 or 27, identify the exact failure: lack of ordinary diligence that caused loss, failure to remove after notice, failure to provide a foreign merchant’s contact details, or failure to act against prohibited or dangerous goods after notice.
5. Escalate with the complete record. If unresolved, follow CyberCode’s step-by-step guide on filing a DTI complaint against an online seller. Name the seller and platform where the facts justify both, and attach the internal ticket and timeline.

Do not miss a shorter platform deadline while waiting for day seven. Start the return, refund or dispute process immediately. The seven-day rule concerns exhaustion of the internal mechanism; it is not a reason to delay an in-app claim.

Worked examples

Example 1: defective appliance from an identifiable local seller

Mara buys a small appliance through a marketplace. It arrives defective. The seller is clearly identified, the platform opens a return case, and the listing does not involve a prohibited or dangerous product. The seller is ordinarily the primary party responsible for the remedy. The defect alone does not prove platform liability.

Example 2: foreign merchant details withheld after notice

Paolo’s order from a foreign seller never arrives. The merchant has no Philippine legal presence. Paolo asks the platform through a dated ticket for usable merchant contact details, but the platform does not provide them. Those facts may engage Section 26(c); Paolo should preserve the request, ticket and response rather than relying only on the missing order.

Example 3: dangerous product remains listed after notice

Lea reports a product that is subject to a documented safety warning and gives the platform the exact listing URL and supporting material. The listing remains accessible and purchasable after the notice. Section 27 may become relevant if the item is prohibited, imminently injurious, unsafe or dangerous and the platform failed to act expeditiously. A regulator or court would still assess the evidence and circumstances.

Important limits

• C2C transactions: RA 11967 excludes consumer-to-consumer transactions. Other contract, fraud, criminal or platform-policy remedies may still matter.
• Payment disputes: A bank, e-wallet or payment processor may have a separate dispute process and regulator. Marketplace liability and payment reversal are different questions.
• Fraud: A scam may require police, cybercrime or financial-account action in addition to a consumer complaint. Preserve evidence before confronting an account that may disappear.
• Foreign platforms: Lack of a Philippine office does not by itself remove a business from the Act. Section 5 addresses businesses that avail of the Philippine market and have minimum contacts here.
• Time limit: Section 28 states that a consumer may claim damages in court or before the DTI within two years from the time the cause of action arose. Do not treat that outside limit as permission to postpone a platform dispute.

Frequently asked questions

Can I name both the seller and marketplace in a DTI complaint?

You may identify both when the facts support claims against both, but explain each party’s conduct separately. The seller’s defective performance does not automatically establish a Section 26 or 27 claim against the platform.

Is an ignored support ticket enough to make the marketplace liable?

Not by itself. An ignored ticket is useful evidence, but the relevant statutory test still needs to be connected to the loss or to the platform’s post-notice duty. Keep the ticket, dates, content and result.

Does “subsidiary liability” mean I must sue the seller first?

Section 26 describes the platform’s liability as subsidiary, while Section 25 makes the seller primarily liable. The exact parties, sequencing and proof in a particular administrative or civil case can depend on the claim and forum. For a consumer complaint, the practical course is to identify both parties, use the internal redress mechanism, and present the facts supporting each liability theory.

Where can I read the controlling sources?

• Senate issuance record for Republic Act No. 11967
• Supreme Court E-Library copy of Republic Act No. 11967
• Accessible text of RA 11967, Sections 3 and 20–28
