Businesses frequently disclose sensitive information during employment, negotiations, investments, software development, outsourcing, construction projects, mergers, and settlement discussions. Without legal protection, confidential information may be copied, disclosed, or used against the disclosing party.

For this reason, Confidentiality Agreements (NDAs) in the Philippines have become one of the most commonly used commercial contracts. A properly drafted NDA can protect trade secrets, business strategies, customer information, financial records, pricing structures, proprietary technology, and other confidential business information.

Philippine law generally recognizes and enforces Confidentiality Agreements (NDAs) in the Philippines, provided their provisions are reasonable and do not violate the Constitution, statutes, morals, public order, or public policy.

This guide explains how Confidentiality Agreements (NDAs) in the Philippines work, when courts enforce them, their legal limitations, important Supreme Court decisions, and practical drafting tips.

What Are Confidentiality Agreements (NDAs) in the Philippines?

A Confidentiality Agreement, commonly known as a Non-Disclosure Agreement (NDA), is a legally binding contract in which one or more parties agree to keep specified information confidential and restrict its use or disclosure.

Confidentiality Agreements (NDAs) in the Philippines are commonly used in:

1. Employment contracts
2. Consultancy agreements
3. Vendor and supplier contracts
4. Joint ventures
5. Business acquisitions
6. Due diligence reviews
7. Software development
8. Construction projects
9. Franchise agreements
10. Settlement agreements
11. Mediation proceedings
12. Intellectual property transactions

The objective is to protect confidential information from unauthorized disclosure while allowing legitimate business relationships to proceed.

Are Confidentiality Agreements (NDAs) in the Philippines Enforceable?

Yes.

As a general rule, Confidentiality Agreements (NDAs) in the Philippines are enforceable under the principle of contractual autonomy embodied in Article 1306 of the Civil Code.

Article 1306 provides that contracting parties may establish such stipulations, clauses, terms, and conditions as they deem convenient, provided these are not contrary to law, morals, good customs, public order, or public policy.

Likewise, Article 1159 of the Civil Code provides that obligations arising from contracts have the force of law between the parties and must be complied with in good faith.

Accordingly, courts generally enforce valid confidentiality agreements according to their terms.

Supreme Court Recognition of NDAs

In Century Properties, Inc. v. Babiano, G.R. No. 220978, July 5, 2016, the Supreme Court upheld a confidentiality and non-compete clause contained in an employment agreement.

The Court emphasized that clear contractual provisions are generally enforceable when they do not violate law or public policy.

Similarly, in Noell Whessoe, Inc. v. Independent Testing Consultants, Inc., G.R. No. 199851, November 07, 2018, the Supreme Court recognized the existence of a separate Confidentiality Agreement executed as part of a commercial subcontracting arrangement.

These decisions demonstrate that Philippine courts generally respect properly drafted confidentiality obligations.

Legal Limits of Confidentiality Agreements (NDAs) in the Philippines

Although generally enforceable, Confidentiality Agreements (NDAs) in the Philippines are not unlimited.

Several legal principles restrict the scope of confidentiality clauses.

NDAs Cannot Override the Constitution or Existing Laws

An NDA cannot prohibit disclosures that are required by law.

In Colmenares v. Duterte, G.R. No. 252578. December 07, 2021, the Supreme Court held that confidentiality clauses in government foreign loan agreements cannot override constitutional requirements concerning transparency and public disclosure.

Accordingly, parties cannot use an NDA to conceal information that must legally be disclosed.

Mediation Communications Receive Independent Statutory Protection

Under the Alternative Dispute Resolution Act of 2004 (Republic Act No. 9285), mediation communications are generally privileged, confidential, and inadmissible in court.

Because confidentiality is already protected by statute, mediation NDAs often serve to clarify:

1. permitted disclosures;
2. handling of documents;
3. return or destruction of materials;
4. practical confidentiality procedures.

Confidentiality May Be Waived

Confidentiality rights may also be waived under applicable law.

Republic Act No. 9285 recognizes that mediation confidentiality may be waived under specified circumstances by the appropriate persons.

Consequently, parties should carefully draft waiver provisions to avoid unintended disclosure.

What Makes Confidentiality Agreements (NDAs) in the Philippines Enforceable?

Several factors significantly affect enforceability.

Clearly Define Confidential Information

Avoid vague language such as:

“All company information.”

Instead, identify categories such as:

1. financial statements;
2. software source code;
3. customer databases;
4. marketing strategies;
5. pricing information;
6. manufacturing processes;
7. technical drawings;
8. trade secrets.

Specific definitions reduce ambiguity.

Specify the Permitted Purpose

The agreement should clearly state how confidential information may be used.

Typical purposes include:

1. evaluating a business acquisition;
2. employment performance;
3. software development;
4. project implementation;
5. due diligence;
6. consulting services.

Limiting the permitted purpose strengthens enforceability.

Include Reasonable Exceptions

Well-drafted Confidentiality Agreements (NDAs) in the Philippines usually exclude information that:

1. is already publicly available;
2. becomes public without fault of the receiving party;
3. is independently developed;
4. is lawfully received from another source;
5. must be disclosed pursuant to law, subpoena, or court order.

These exceptions are consistent with accepted commercial practice.

Include a Survival Clause

Many confidentiality obligations continue after:

1. resignation;
2. termination;
3. expiration of the contract;
4. completion of negotiations.

The agreement should expressly state the duration of continuing confidentiality obligations.

Provide Appropriate Remedies

An NDA may authorize the injured party to seek:

1. injunctions;
2. actual damages;
3. attorney’s fees where legally recoverable;
4. recovery of confidential materials;
5. destruction of confidential documents.

The remedies should be reasonable and proportionate to the legitimate interests being protected.

Common Situations Where NDAs Are Used

Businesses commonly require Confidentiality Agreements (NDAs) in the Philippines for:

Employment

Employers often protect:

• customer information;
• trade secrets;
• internal processes;
• software;
• pricing;
• confidential reports.

In Citigroup Business Process Solutions Pte. Ltd. v. Corpuz, G.R. Nos. 208738-39, June 05, 2024, the Supreme Court discussed confidentiality obligations in the employment setting while emphasizing that disciplinary action must still satisfy labor law requirements.

Settlement Agreements

Settlement agreements frequently include confidentiality provisions.

In Tankiang v. Alaraz, G.R. No. 181675, June 22, 2009, the Supreme Court recognized a settlement agreement containing confidentiality provisions while allowing disclosure where required by law or competent authority.

Construction and Commercial Projects

Contractors, consultants, engineers, architects, subcontractors, and suppliers routinely exchange proprietary project information.

Separate NDAs reduce the risk of unauthorized disclosure.

Mergers, Acquisitions, and Due Diligence

Potential buyers routinely obtain confidential business information before deciding whether to purchase a company.

NDAs protect:

1. financial records;
2. client lists;
3. contracts;
4. intellectual property;
5. operational information.

Common Mistakes When Drafting NDAs

Businesses frequently make these mistakes:

1. Defining confidential information too broadly.
2. Failing to identify exclusions.
3. Omitting survival clauses.
4. Omitting return or destruction provisions.
5. Failing to include disclosure exceptions required by law.
6. Using foreign templates that conflict with Philippine law.
7. Treating every piece of information as confidential without distinction.

Poor drafting often weakens enforcement.

Frequently Asked Questions (FAQs)

Conclusion

Confidentiality Agreements (NDAs) in the Philippines are powerful legal tools for protecting confidential business information, trade secrets, proprietary technology, customer relationships, and commercially sensitive data.

Philippine courts generally enforce properly drafted NDAs that are clear, reasonable, and consistent with the Civil Code, constitutional principles, and applicable statutes. However, confidentiality clauses cannot override mandatory legal disclosures, constitutional rights, or public policy.

Whether the NDA relates to employment, commercial transactions, software development, mergers and acquisitions, construction projects, or settlement agreements, careful drafting is essential. Businesses and individuals should ensure that confidentiality agreements are tailored to the specific transaction and comply with Philippine law to maximize enforceability.
