Quick answer

If a person or business used your property address without permission, act promptly: verify exactly where the address appears, document that you did not authorize its use, send a written demand to the registrant, and notify the government offices holding the incorrect record—usually the DTI or SEC, the city or municipal Business Permits and Licensing Office, and the BIR Revenue District Office.

Using your address does not, by itself, make you the business owner, guarantor, taxpayer, employer, or debtor. Contracts generally bind only their parties under Article 1311 of the Civil Code. A corporation also has a legal personality separate from its shareholders and property owners. However, an incorrect registered address can bring tax notices, collection letters, inspections, customers, court papers, or law-enforcement inquiries to your property, so a clear paper trail matters.

The correct response depends on what was registered, who made the filing, and whether any lease, consent, identification document, or signature was falsified.

First, confirm what “using your address” means

An address may appear in several different records:

A DTI business-name registration for a sole proprietorship
SEC records for a corporation or partnership
BIR registration records or invoices
A barangay clearance or mayor’s/business permit
An online marketplace, social-media page, website, invoice, delivery account, loan application, or bank record
A contract, lease, utility bill, affidavit, or proof-of-address document
A signboard or an operation physically conducted at the property

These are not interchangeable. A DTI business-name registration, for example, registers the name of a sole proprietorship; it is not by itself authority to operate at the property. A business generally also needs applicable local permits and tax registration.

There may also be an innocent explanation. A former tenant may have failed to update an old address, an encoder may have made an error, or someone may have used the address only for correspondence. Do not accuse anyone publicly of fraud until the records and documents are checked.

Step 1: Preserve evidence before contacting the registrant

Create a dated file containing:

Screenshots, advertisements, invoices, delivery labels, directory listings, and social-media pages showing the address
The complete business name and any DTI, SEC, BIR, permit, or registration number
Photographs of signs, deliveries, visitors, or business activity at the property
Unopened envelopes addressed to the business
Dates, names, identification details, and stated purpose of inspectors, process servers, collectors, customers, or delivery riders
Your title, tax declaration, deed of sale, lease, property-management record, or other proof of your legal relationship to the property
Existing and former leases, including their effective and termination dates
Messages showing whether consent was requested, granted, restricted, or withdrawn
Specimen signatures and copies of any document suspected to contain a forged signature
CCTV footage, access logs, and witness statements, if relevant

Keep original documents and unedited electronic files. Back them up. A screenshot is more useful when it shows the URL, account name, and date, not merely the disputed address.

If you are a tenant rather than the owner, notify the owner or property administrator in writing. If the suspected registrant is or was a tenant, review the lease before asserting that all business use was unauthorized.

Step 2: Verify the business and its legal form

For a suspected sole proprietorship, use the official DTI Business Name Search. The search requires an exact business name, so try the spelling shown on the document you received. The DTI BNRS also provides registration services and guidance.

For a corporation or partnership, obtain or verify its SEC records. The SEC’s official company-information services may show the registered office, registration number, and status. If ordinary public lookup does not provide enough detail, submit an inquiry or records request through the SEC iMessage system.

Also ask the city or municipality’s Business Permits and Licensing Office—often called the BPLO—to check whether a permit or pending application uses the address. Business permits are issued by the city or municipal government, and local documentary requirements and procedures vary.

Ask the BIR Revenue District Office with jurisdiction over the address whether it can receive your written report concerning a business that is not operating there. Do not expect the BIR to disclose confidential taxpayer information to you; the purpose of the report is to place your denial and evidence on record.

Step 3: Send a written notice and demand

Send the registrant a calm, factual notice stating:

Your name and legal relationship to the property
The address being used
Where you discovered the use
That you did not authorize it, or that any prior authority ended on a specified date
A demand to stop representing the property as its office or business address
A demand to correct all DTI, SEC, BIR, LGU, marketplace, banking, and commercial records
A reasonable deadline for written confirmation and proof of correction
A request for copies of any document supposedly showing your consent

There is no single statutory deadline that fits every unauthorized-address case. A short, reasonable period—such as several business days—may be used in the demand, but urgent reports to agencies should not be delayed while waiting for a reply.

Send the notice through a traceable method, such as registered mail, a reputable courier with proof of delivery, or email with delivery records. Keep the signed letter, attachments, receipt, tracking result, and any response. If the registrant’s real location is unknown, document your attempts and proceed with agency reports.

Step 4: Report the incorrect record to the proper offices

If it is a DTI-registered sole proprietorship

DTI business-name registration applies to sole proprietors. The proprietor—not the business name as a separate entity—is legally responsible for the enterprise. The Supreme Court has repeatedly recognized that a sole proprietorship has no juridical personality separate from its owner, including in Mangila v. Court of Appeals.

Submit a written concern to DTI identifying the exact business name and explaining that your address was used without permission. Attach:

Proof of identity
Proof of ownership, tenancy, or administration
Evidence showing the registered or advertised address
Your sworn or signed denial of consent
The demand letter and proof of delivery, if available
Any suspected false or falsified supporting document

The DTI BNRS FAQ identifies bnrshelpdesk@dtiphmail.dti.gov.ph for BNRS concerns. Ask DTI whether the matter should be handled as a correction, investigation, or formal proceeding affecting the registration. You generally cannot cancel another person’s registration through the ordinary owner-controlled cancellation feature merely because your property address appears in it.

If it is an SEC-registered corporation or partnership

A corporation’s articles must state its principal office in the Philippines under the Revised Corporation Code. SEC registration systems instruct applicants to provide correct and complete principal-office information.

File a ticket through SEC iMessage, the SEC’s official platform for inquiries, complaints, incidents, and requests. Include the entity’s exact name and SEC registration number if known, and request that the SEC examine the allegedly false or outdated principal-office address.

Only the entity or its duly authorized representative can normally file its corporate amendment. The SEC’s eAMEND portal allows qualifying registered entities to apply for a change of principal office, but a property owner should not access the entity’s account, impersonate an officer, or file an amendment on its behalf.

Do not assume that every incorrect address automatically constitutes a criminal offense. Liability under the Revised Corporation Code for false or misleading reports depends on the particular filing, the responsible person’s knowledge and intent, and the evidence.

Notify the city or municipal BPLO

Give the BPLO a written notice that you dispute the business’s authority to use or operate from the property. Request:

Verification of whether a permit or application uses the address
Inspection, if the records indicate operations there
Annotation, correction, denial, suspension, or other action allowed by the local ordinance and due process
A receiving copy or reference number for your report

Also notify the barangay if it issued a clearance or if customers, employees, inventory, or business activities are actually appearing at the property.

Local requirements differ. The BPLO may ask for a title, tax declaration, lease, barangay certification, owner’s authorization, occupancy document, or sworn statement. Ask for its current checklist rather than relying on requirements from another city.

Notify the BIR

Send a signed report to the BIR RDO with jurisdiction over the address. State that:

You are the owner, tenant, or administrator;
The named taxpayer does not operate there or lacks authority to use the address;
You are not its proprietor, officer, employee, or authorized representative, if true; and
You request verification and appropriate correction or enforcement.

Attach supporting documents but redact unrelated sensitive information where possible. You may also use the BIR eComplaint system or seek routing assistance through the BIR contact page. The BIR currently lists (02) 8538-3200 and contact_us@bir.gov.ph for taxpayer queries and concerns.

A property owner normally cannot amend another taxpayer’s BIR registration. Your objective is to formally dispute the address and provide evidence to the office authorized to act.

Notify platforms and private organizations

If the address appears on an online marketplace, delivery application, map listing, website, lender’s record, or payment account, use the platform’s impersonation, fraud, privacy, or inaccurate-information channel. Provide only the minimum proof necessary. Ask for removal or correction and preserve the ticket number and response.

If deliveries continue, tell the courier that the addressee does not operate at the location. Do not accept cash-on-delivery parcels, sign as the business, or represent yourself as its agent.

What to do with mail, tax notices, and court papers

Do not open mail addressed solely to another person or business. Mark ordinary mail “not at this address” or “moved—address used without authority,” return it through the carrier, and keep a photograph of the unopened envelope and notation.

Do not destroy official notices. If a sheriff, process server, tax officer, or regulator visits:

Identify yourself truthfully.
State that the business does not operate there and that you are not authorized to receive documents for it, if accurate.
Show proof of your relationship to the property if appropriate.
Ask the officer to record your statement in the return, report, or field notes.
Record the officer’s name, office, case or reference number, and contact details.
Notify your lawyer immediately if your property, name, or interests appear in the document.

Service of summons on a domestic corporation is governed by Rule 14 of the Rules of Civil Procedure and generally concerns service on specified corporate officers or, in stated circumstances, designated recipients—not merely any unrelated person found at a listed address. Still, never ignore a document bearing your own name or naming you as a defendant. Court deadlines can run from valid service, and the correct response depends on the document and manner of service.

Are you liable for the business’s debts or taxes?

Ordinarily, no. Ownership of the premises or receipt of misdirected correspondence does not alone make you liable.

Under Article 1311 of the Civil Code, contracts generally take effect only between the parties, their assigns, and heirs, subject to the law’s exceptions. Corporate obligations are generally the corporation’s obligations because it has a personality separate from its shareholders and other persons.

The analysis changes if you:

Signed as borrower, co-maker, guarantor, surety, partner, proprietor, or corporate officer
Knowingly allowed your documents or property to be used to obtain credit or permits
Participated in or benefited from the business
Held the business out as your own
Leased the premises for the disputed activity
Accepted service or correspondence as an authorized representative
Own the sole proprietorship using the business name

For a sole proprietorship, the registered proprietor and the enterprise are not separate legal persons. But an unrelated property owner does not become the proprietor merely because the proprietor entered that property’s address.

When the Data Privacy Act may help

A street address connected to an identifiable individual can be personal information. If the incident involved your name, identification documents, signature, contact details, or other personal data—not merely the location of a building—the Data Privacy Act of 2012 may apply.

First send the organization or personal information controller a written request to correct, block, remove, or explain the disputed processing. Preserve its response. If your personal information was misused or your data-subject rights were violated, consult the National Privacy Commission’s official guidance on the right to file a complaint.

Not every property-address dispute is automatically a privacy case. A complaint is stronger when the address is linked to you as an identifiable person or when your personal documents were collected, copied, disclosed, or used without a lawful basis.

When to involve the police, NBI, or a lawyer

Seek prompt legal help if you discover:

A forged lease, owner’s authorization, affidavit, signature, identification card, or utility bill
Loans, bank accounts, tax registrations, permits, invoices, or contracts made in your name
Repeated deliveries of suspicious goods or visits connected with illegal activity
Threats, harassment, trespass, or refusal to stop actual operations on the property
A search warrant, subpoena, summons, levy, closure order, tax assessment, or other compulsory process
Use of the address as part of an investment, lending, recruitment, e-commerce, or identity-fraud scheme
Risk that evidence or CCTV footage will be erased
A tenant operating outside the lease or refusing to vacate

A police or NBI report can document the incident, but it does not automatically cancel a DTI, SEC, BIR, or local-government record. Separate reports to the record-holding agencies remain necessary.

Possible criminal or civil remedies depend on proof. Falsification, use of falsified documents, fraud, computer-related offenses, privacy violations, damages, injunction, or breach-of-lease remedies each have different legal elements. A lawyer should review the actual document and evidence before a specific accusation is made.

Common mistakes to avoid

Assuming a DTI certificate is the same as a mayor’s permit or SEC registration
Confronting the suspected registrant before preserving online and physical evidence
Posting accusations, personal details, or registration documents publicly
Signing for mail, parcels, or legal papers as though you represent the business
Opening or discarding someone else’s mail
Trying to enter the business’s government account or file changes in its name
Reporting only to one agency when the address appears in several systems
Sending original titles, IDs, or evidence without keeping secure copies
Accepting a verbal promise to correct the address without written proof
Ignoring documents because the business is “not yours”
Claiming fraud when the evidence may show an expired lease, clerical error, or unreported transfer

A practical written-report checklist

Each agency submission should contain:

Your full name and reliable contact details
Your relationship to the property
The complete disputed address
The exact business or entity name
Registration and permit numbers, if known
A short chronological statement of facts
A clear statement that consent was never given, was limited, or ended on a particular date
The specific correction, verification, inspection, or investigation requested
Numbered attachments
Your signature and date
A request for a stamped receiving copy, ticket number, or written acknowledgment

Use facts you can prove. If something is uncertain, say “I was informed,” “the document appears to show,” or “I request verification” rather than presenting it as established fact.

FAQ

Can someone register a business at my house without my signature?

The answer depends on the registration system, entity type, and supporting documents required at the time of filing. Some initial registrations may collect address information without obtaining a separate notarized consent from the property owner. That does not create a right to occupy or use the property and does not prevent you from disputing false information.

Can I cancel the business registration myself?

Usually not. Ordinary cancellation or amendment is generally filed by the proprietor, corporation, partnership, or authorized representative. As the property owner or lawful occupant, you can submit evidence and ask DTI, SEC, the BPLO, or BIR to investigate and take the action allowed by their rules.

Should I confront the person first?

Preserve evidence first. A written demand may resolve an error quickly, but do not delay urgent agency, police, or legal action where there is suspected forgery, active fraud, illegal activity, or compulsory legal process.

Does the registration give the business ownership or tenancy rights?

No. Listing an address in a registration does not transfer title, create a lease, or by itself prove a right to possess the property. Property and tenancy rights depend on the title, lease, consent, and surrounding facts.

Can creditors seize my property because the business used my address?

The address alone does not make your property answer for another person’s obligations. If a sheriff, creditor, or collector claims otherwise, present proof of ownership and your written dispute, do not sign admissions, and obtain legal advice immediately if a levy or seizure is threatened.

What if the business belonged to a former tenant?

Check the lease and termination documents. Demand that the former tenant update every registration and account, and inform the relevant agencies that the tenancy and any address authority ended on a specific date. Attach the lease termination, turnover record, or comparable proof.

What if I previously allowed the address to be used?

State the precise scope and duration of your consent. If it was revoked or expired, send written notice and retain proof of receipt. Whether withdrawal alone is sufficient may depend on the lease, contract, corporate documents, and agency rules.

Is there a deadline for reporting the address?

There is no single universal deadline for every agency or claim. Report promptly. Court papers, tax processes, privacy complaints, civil claims, and criminal offenses may have separate procedural or prescriptive periods, so obtain legal advice immediately when a formal document, forged instrument, financial loss, or threatened enforcement action is involved.
