When a sole proprietorship becomes a One Person Corporation (OPC), its existing contracts do not automatically disappear—but they also do not automatically move to the OPC. The critical point is that a sole proprietorship and an OPC are legally different. The sole proprietorship is legally the owner himself or herself, while the OPC is a separate corporation created only after the Securities and Exchange Commission (SEC) issues its certificate of incorporation. Existing leases, loans, supplier agreements, customer contracts, employment arrangements, and other obligations must therefore be reviewed and transferred properly.

The Short Answer: Existing Contracts Stay With the Sole Proprietor

A sole proprietorship has no legal personality separate from its owner. In Yon Mitori International Industries v. Union Bank of the Philippines, G.R. No. 225538, October 14, 2020, the Supreme Court emphasized that a sole proprietorship is not a separate juridical person. A contract signed under the business name is legally a contract of the registered owner. (Lawphil)

An OPC, on the other hand, is a corporation with one stockholder under Sections 116 to 132 of the Revised Corporation Code, Republic Act No. 11232. Once incorporated, it has its own corporate personality, assets, obligations, tax registration, permits, and capacity to enter into contracts. (Lawphil)

This means:

Contracts signed by the sole proprietor remain enforceable against the proprietor.
The OPC does not automatically become the new contracting party.
The proprietor remains personally liable for old debts unless the creditor clearly agrees to release him or her.
Contractual rights may sometimes be assigned to the OPC, but contractual obligations generally require the other party’s consent.
Some contracts cannot be transferred at all because of their nature, the wording of the contract, or a specific law.

A Sole Proprietorship Does Not Legally “Convert” Into an OPC

People commonly describe the process as “converting a sole proprietorship into an OPC,” but legally, it is usually a two-stage transaction:

A new OPC is incorporated with the SEC.
The sole proprietor transfers the business, assets, contracts, employees, and operations to the OPC.

Section 131 of RA 11232 provides a formal conversion procedure only when an ordinary stock corporation becomes an OPC after one person acquires all its shares. In that situation, the converted OPC automatically succeeds to the ordinary corporation’s outstanding liabilities.

That statutory succession rule does not apply to a DTI-registered sole proprietorship. A sole proprietor must create a new OPC and separately document what the OPC will acquire or assume. (SEC Appointment System)

The Department of Trade and Industry also does not allow the ownership of a registered business name to be transferred. Its current guidance states that the owner must cancel the old business-name registration when the business is sold or transferred. (BNRS)

Why Contracts Do Not Automatically Transfer

Article 1159 of the Civil Code of the Philippines, Republic Act No. 386 states that contractual obligations have the force of law between the contracting parties and must be complied with in good faith. The creation of an OPC does not erase or rewrite those obligations. (Lawphil)

Article 1311 further provides that contracts generally take effect only between the parties, their assigns, and heirs, except when the rights or obligations are non-transferable by:

Their nature;
The parties’ agreement; or
A provision of law. (Lawphil)

The practical result is that contract rights and contract obligations must be treated differently.

Assignment of Contractual Rights

A proprietor may sometimes assign rights to the OPC, such as:

The right to collect customer receivables;
The right to receive deliveries;
The right to enforce warranties;
The right to receive commissions or service fees; or
Rights under transferable supply or distribution agreements.

However, the contract may prohibit assignment or require prior written consent.

For receivables, written notice to the customer or debtor is important. Under Article 1626 of the Civil Code, a debtor who pays the original creditor before learning of the assignment is generally released from the obligation. An assignment intended to affect third persons should also be placed in a public instrument under Article 1625. In practice, this usually means using a notarized deed of assignment. (Lawphil)

Transfer of Contractual Obligations

Moving obligations is more difficult. Examples include:

A bank loan;
The obligation to pay rent;
The duty to deliver products;
Warranty and refund obligations;
Service-level commitments;
Customer deposits;
Supplier payables; and
Obligations secured by a mortgage, guaranty, or suretyship.

Under Articles 1291 to 1293 of the Civil Code, substituting a new debtor requires the creditor’s consent. The proprietor and the OPC cannot privately agree between themselves that the OPC will replace the proprietor and then force the creditor to accept the change. (Lawphil)

Novation Is Usually the Safest Method

Novation means replacing or materially changing an existing obligation with the agreement of the necessary parties. For a complete transfer, the usual document is a tripartite agreement among:

The sole proprietor;
The OPC; and
The customer, landlord, lender, supplier, or other counterparty.

The agreement should clearly state:

That the OPC replaces the proprietor from a specified effective date;
Which rights and obligations are transferred;
Whether the proprietor is fully released from future and past liabilities;
Whether guarantees and security arrangements remain effective;
How deposits, advance payments, warranties, and pending claims will be handled; and
Whether all other terms of the original contract remain unchanged.

Novation is never presumed. In Bendecio v. Bautista, G.R. No. 242087, December 7, 2021, the Supreme Court explained that merely accepting payment or performance from a third person does not release the original debtor when there is no agreement expressly releasing that debtor. The result may simply be an additional debtor, with the original debtor remaining liable. (Lawphil)

Ways to Handle Existing Contracts

Method	What Happens	Is the Proprietor Released?	Best Used For
Keep the contract under the proprietor	The old contract continues until expiry or termination	No	Short-term contracts close to expiry
Assign contractual rights	OPC receives specified benefits, such as receivables	Usually no	Collection of accounts and transferable rights
OPC assumes obligations	OPC promises to perform the proprietor’s duties	Not necessarily	Temporary arrangements where the counterparty does not release the proprietor
Amend the contract	Parties add the OPC or change selected provisions	Only if clearly stated	Continuing supplier or customer relationships
Execute a full novation	OPC replaces the proprietor as contracting party	Yes, if the release is express	Leases, loans, major customer contracts and long-term agreements
Enter into a new contract	Old contract is terminated and replaced	Depends on the termination document	Contracts that are difficult to amend

The agreement should expressly use words such as “released,” “discharged,” “substituted,” and “no longer liable” when the intention is to end the proprietor’s personal liability.

Step-by-Step Process for Moving Contracts to the OPC

1. Incorporate the OPC First

The OPC must exist before it can validly acquire property or become a contracting party.

The SEC currently accepts OPC applications through eSPARC. Applications that fit OneSEC or SEC ZERO requirements may be processed electronically, while regular applications are reviewed through the regular eSPARC system. The SEC states that regular-processing applicants should generally receive a review status within seven working days, although corrections, regulated activities, foreign-equity questions, and name issues may extend the process. (Esparc)

An OPC generally needs:

Articles of incorporation;
A nominee and alternate nominee;
Acceptance documents for the nominee and alternate nominee;
A corporate secretary who is not the single stockholder;
A treasurer;
Beneficial ownership information; and
The required SEC authentication or digital signing.

2. Prepare a Complete Contract Inventory

List every arrangement connected with the sole proprietorship, including contracts that may not be stored in a formal contract folder.

Check:

Office, warehouse, and equipment leases;
Bank loans and credit lines;
Supplier purchase agreements;
Customer service agreements;
Distributor or dealership arrangements;
Franchise agreements;
Insurance policies;
Software subscriptions;
Payment-gateway and merchant-acquiring agreements;
Employment contracts;
Government contracts;
Intellectual-property licences;
Data-processing agreements;
Utility accounts;
Customer deposits and prepaid packages; and
Oral or informal arrangements supported by emails, purchase orders, or invoices.

Record the counterparty, expiration date, renewal date, termination period, security deposit, outstanding balance, and transfer restrictions for each contract.

3. Review Assignment, Consent, and Termination Clauses

Look for language involving:

Assignment;
Transfer;
Delegation;
Subcontracting;
Change of ownership;
Change of legal structure;
Change of control;
Prior written consent;
Personal performance;
Automatic termination; or
Events of default.

An anti-assignment clause may allow the counterparty to terminate the contract or reject the transfer. Moving operations to the OPC without consent may therefore create a breach even when the same person continues managing the business.

4. Pass an OPC Written Resolution

Section 128 of RA 11232 allows an OPC to act through a written resolution signed and dated by the single stockholder and recorded in the corporate minutes book.

The resolution should authorize the OPC to:

Acquire specified business assets;
Accept assignments of contracts and receivables;
Assume identified liabilities;
Sign novation agreements;
Open bank and payment accounts;
Hire or absorb employees; and
Authorize a named officer to sign transfer documents. (SEC Appointment System)

This helps establish that the OPC—not merely the individual owner acting informally—approved the transaction.

5. Document the Transfer of the Business and Assets

A general business transfer agreement, deed of sale, or deed of exchange may cover assets such as:

Inventory;
Furniture and equipment;
Vehicles;
Receivables;
Trade names and branding;
Websites and domain names;
Copyrights and trademarks;
Customer lists, subject to privacy requirements;
Security deposits;
Prepayments; and
Selected liabilities.

Attach detailed schedules. Avoid vague wording such as “all business assets” when the business owns registered vehicles, land, trademarks, mortgaged equipment, or substantial receivables.

6. Obtain Contract-Specific Consents

For important contracts, send the counterparty:

The OPC’s SEC certificate of incorporation;
Articles of incorporation;
Corporate resolution;
BIR Certificate of Registration, when available;
Updated business permits;
Draft deed of assignment or novation;
Updated billing and payment instructions; and
Identification and authority documents of the OPC signatory.

Banks, landlords, franchisors, insurers, payment processors, large corporations, and government agencies often use their own consent or onboarding forms.

7. Establish a Clear Cutover Date

Choose a specific date when:

New sales will be invoiced by the OPC;
Payments must be deposited into the OPC’s account;
New purchase orders will be issued by the OPC;
Employees will move to the OPC payroll;
The OPC will assume warranty and service obligations;
Old and new accounts will be separated; and
The sole proprietorship will stop entering into new contracts.

Do not use the sole proprietor’s invoices, bank account, tax registration, or official receipts for OPC transactions after the cutover.

8. Close the Sole Proprietorship Only After the Transition Is Stable

Do not cancel the sole proprietorship immediately if it still has:

Uncollected receivables;
Pending tax returns;
Unsettled employee claims;
Customer deposits;
Open warranties;
Outstanding loans;
Pending litigation; or
Contracts awaiting consent.

Closing the DTI registration does not extinguish the proprietor’s debts. The owner must separately address the LGU business permit, BIR registration, books and invoices, and other agency registrations.

The BIR requires a formal application for closure or cancellation of business registration. Outstanding returns, open cases, unused invoices, books of accounts, and unpaid taxes commonly need to be resolved before the registration is fully closed. The applicable requirements should be confirmed with the registered Revenue District Office or the BIR’s official closure service. (Bureau of Internal Revenue)

Special Contracts That Need Extra Care

Commercial Leases

Article 1649 of the Civil Code states that a lessee cannot assign a lease without the lessor’s consent unless the lease itself provides otherwise. Even when the owner, premises, employees, and business remain the same, the OPC is a different lessee. (Lawphil)

The landlord may require:

A new lease;
A lease amendment;
Updated security deposits;
Personal guarantees from the stockholder;
New postdated checks; or
Updated insurance coverage.

Operating under the old lease without written consent may expose the proprietor to continued liability and the OPC to possible eviction or unauthorized-occupancy issues.

Loans, Mortgages, and Guarantees

A bank loan does not move to the OPC merely because the OPC starts paying the installments. The bank may require:

A new credit evaluation;
A formal assumption agreement;
New promissory notes;
Registration of new security documents;
Updated appraisals;
Personal guarantees; or
Full payment of the old loan followed by a new OPC loan.

Unless the bank expressly releases the proprietor, the proprietor normally remains personally liable.

Customer and Supplier Contracts

For ordinary customer or supplier agreements, an amendment or novation may be sufficient. The document should address:

Existing purchase orders;
Advance payments;
Credit balances;
Product returns;
Warranties;
Rebates;
Confidentiality obligations;
Pending disputes; and
Data already collected from customers.

For receivables, notify customers in writing of the assignment and provide verified OPC bank details. A customer who pays the proprietor before receiving notice may generally be treated as having validly paid the original creditor.

Employees

Employees are not assets that can simply be transferred through a business-transfer agreement. In Bank of the Philippine Islands v. BPI Employees Union-Davao Chapter, G.R. No. 164301, August 10, 2010, the Supreme Court stated that an employer cannot unilaterally transfer employees to another employer like property. (Lawphil)

A well-documented absorption arrangement should address:

The employee’s consent;
Recognition of the original hiring date;
Continuity of tenure;
Salary and position;
Accrued leave;
Retirement and separation benefits;
Service incentive leave;
Existing disciplinary records;
Loans and deductions;
SSS, PhilHealth, and Pag-IBIG reporting; and
Responsibility for pre-transfer labor claims.

Where the sole proprietor truly closes the old establishment and terminates employees, Article 298 of the Labor Code may require written notice to the employee and the Department of Labor and Employment at least one month before termination, together with applicable separation pay. A paper “termination and rehiring” arrangement used only to erase tenure or reduce benefits may create illegal-dismissal or diminution-of-benefits disputes. (Lawphil)

Licences, Permits, and Accreditations

Business permits and regulatory licences are generally issued to a specific person or entity. They should not be treated as ordinary transferable contracts.

The OPC may need new or amended registrations with:

The barangay;
City or municipal Business Permits and Licensing Office;
BIR;
SSS;
PhilHealth;
Pag-IBIG Fund;
Food and Drug Administration;
Department of Environment and Natural Resources;
Philippine Contractors Accreditation Board;
Land Transportation Office;
Intellectual Property Office of the Philippines; or
Other industry regulators.

Government contracts, permits, franchises, and accreditations may require prior agency approval before assignment.

Personal Data and Customer Records

Transferring customer databases to the OPC involves the Data Privacy Act of 2012, RA 10173. Review privacy notices, contractual confidentiality clauses, data-sharing arrangements, and the legal basis for transferring personal information.

Customers should be clearly informed of the new data controller where required. Access controls, retention periods, breach procedures, and vendor agreements should also be updated.

Tax Consequences of Transferring Assets to the OPC

The transfer of business assets is not automatically tax-free merely because the same person owns the sole proprietorship and the OPC.

A direct sale of assets may create:

Income tax or capital-gains consequences;
Value-added tax, where applicable;
Creditable withholding tax;
Documentary stamp tax;
Transfer taxes;
Registration fees; and
Local taxes.

Section 40(C)(2) of the National Internal Revenue Code, as amended by the CREATE Act or RA 11534, may allow nonrecognition of gain or loss when property is transferred to a corporation solely in exchange for shares and the transferor gains control of the corporation. A sole proprietor who receives all the shares of an OPC may potentially satisfy the control requirement, but the transaction must still meet all statutory and BIR documentation requirements. (Lawphil)

A deed should not be labelled “tax-free” without confirming:

The nature of each asset;
Whether consideration consists solely of shares;
The transferor’s resulting control;
The substituted tax basis;
Required accounting entries;
BIR filings;
Electronic Certificate Authorizing Registration requirements; and
Taxes or fees that remain payable despite nonrecognition treatment.

Real-property transfers must also be registered with the Registry of Deeds and supported by the appropriate BIR clearance or eCAR.

Foreign Owners and Documents Signed Abroad

A foreign natural person may organize an OPC, subject to constitutional and statutory restrictions on foreign participation in the specific business. (SEC Appointment System)

A foreign-owned OPC cannot use incorporation to bypass Philippine land-ownership rules. Article XII, Sections 2, 3, and 7 of the 1987 Constitution restrict the acquisition of Philippine land. A corporation generally must satisfy the applicable Filipino-ownership requirement to acquire private land, while corporations may only lease alienable public land within constitutional limits. (Lawphil)

Foreign owners must also consider whether their industry is reserved partly or entirely for Filipinos.

Documents signed abroad may need:

Notarization in the country of execution;
An apostille where the country is a party to the Apostille Convention; or
Philippine consular authentication where the apostille system does not apply.

SEC ZERO and eSAP may permit remote digital authentication for supported incorporation documents, but separate deeds of sale, assignments, powers of attorney, land documents, and novation agreements may still require notarization or authentication. (Esparc)

Typical Documents and Processing Time

Item	Common Documents	Practical Timing
OPC incorporation	Articles, nominee documents, authentication, beneficial ownership data	One day for qualifying OneSEC cases; regular review may take seven working days or longer
Contract inventory	Contract copies, purchase orders, account schedules	Several days to several weeks
Asset transfer	Deed of sale or exchange, asset schedules, corporate resolution	Several days after valuation and tax review
Contract novation	Original contract, SEC documents, tripartite agreement	A few days for small counterparties; several weeks for banks, landlords, and large companies
Employee transfer	Employee consent, absorption agreement, payroll and benefit records	Ideally completed before the payroll cutover
LGU permits	Barangay clearance, lease, occupancy documents, SEC and BIR records	Varies significantly by city and business activity
BIR registration and closure	Registration forms, returns, books, invoices and tax clearances	New registration may be relatively quick; closure can take longer if there are open cases
Real-property transfer	Notarized deed, tax returns, eCAR, transfer-tax payment, title documents	Commonly several weeks or longer
DTI cancellation	Cancellation request and supporting documents	After the proprietor has stopped using the business name and addressed remaining obligations

The largest delays usually come from incomplete contract records, slow counterparty approvals, landlord or bank requirements, unresolved tax filings, and assets registered under the proprietor’s personal name.

Common Mistakes to Avoid

Assuming the SEC Certificate Transfers Everything

The SEC certificate creates the OPC. It does not transfer old contracts, land, vehicles, receivables, employees, licences, or bank accounts.

Letting the OPC Perform Without Changing the Contract

The counterparty’s acceptance of OPC payments or services may not release the proprietor. Without clear novation, both the OPC and proprietor may become exposed while the original personal liability remains.

Mixing Personal and Corporate Property

Section 130 of RA 11232 places an important burden on an OPC stockholder claiming limited liability. The owner must be able to show that the OPC was adequately financed and that corporate property is separate from personal property. Failure to maintain that separation may lead to personal liability and piercing of the corporate veil. (SEC Appointment System)

Use separate:

Bank accounts;
Accounting records;
Contracts;
Invoices;
Assets;
Tax filings; and
Corporate approvals.

Transferring Assets to Defeat Creditors

Moving assets to the OPC does not lawfully place them beyond the reach of existing creditors. Articles 1313 and 1381 of the Civil Code protect creditors against transfers intended to prevent collection. Transfers made in fraud of creditors may be rescinded, and bad-faith transferees may face liability. (Lawphil)

Closing the Sole Proprietorship Too Early

The proprietor may still need the old registration and bank account to collect assigned receivables, settle taxes, process refunds, complete warranties, or resolve pending claims. Use a controlled transition period rather than an abrupt undocumented shutdown.

Frequently Asked Questions

Are existing contracts cancelled when I register an OPC?

No. Existing contracts remain valid against the sole proprietor unless they expire, are terminated, or are transferred with the required consent.

Do I need to sign completely new contracts?

Not always. A contract amendment, consent to assignment, or tripartite novation may be enough. A new contract is often cleaner when the old agreement is outdated or difficult to amend.

Am I still personally liable for debts incurred by the sole proprietorship?

Yes. Incorporating an OPC does not erase personal liabilities already incurred as a sole proprietor. You remain liable unless the creditor expressly agrees to release you.

Can the OPC collect the sole proprietorship’s unpaid invoices?

Yes, if the receivables are validly assigned. Customers should receive written notice identifying the assigned invoices and the OPC’s verified payment details.

What happens if a customer refuses to transfer the contract?

The contract generally remains with the sole proprietor. The parties may allow it to run until expiry, negotiate new terms, or terminate it according to its provisions. The OPC cannot force the customer to accept a new contracting party.

Can I transfer my office lease without asking the landlord?

Usually not. Article 1649 of the Civil Code requires the lessor’s consent unless the lease expressly permits assignment without consent.

Does the OPC automatically become responsible for old warranties and customer deposits?

No. The transfer agreement and customer arrangements should clearly state whether the OPC assumes them. The proprietor may remain liable if customers never agreed to the substitution.

Do employees automatically become OPC employees?

No. Employment is a personal and consensual relationship. Use written absorption or transfer documents and clearly preserve or settle tenure, benefits, leave credits, and existing claims.

Can I cancel my DTI and BIR registrations immediately after SEC incorporation?

It is usually safer to wait until contracts, receivables, taxes, employees, permits, and pending claims have been addressed. Cancellation does not extinguish existing liabilities.

Can a foreign-owned OPC receive land owned by the sole proprietor?

Not if the OPC fails the constitutional nationality requirements for Philippine land ownership. A foreign-owned OPC may generally lease property instead, subject to applicable law and contract terms.

Key Takeaways

A sole proprietorship and an OPC are legally different contracting parties.
Existing contracts remain with the sole proprietor unless properly transferred.
Contract rights may be assigned, but transferring obligations usually requires the creditor’s consent.
A tripartite novation is the clearest way to replace the proprietor and obtain a release from personal liability.
Leases, loans, employee arrangements, licences, land, and regulated contracts need special handling.
Incorporation alone does not transfer assets, permits, receivables, employees, or debts.
Tax consequences should be reviewed before executing any sale, assignment, or exchange of assets.
The proprietor should keep the old business open long enough to settle remaining contracts, taxes, receivables, and claims.
Separate corporate and personal records must be maintained to preserve the OPC’s limited-liability protection.
