What is a Non-Disclosure Agreement (NDA)?

A Non-Disclosure Agreement (NDA), also called a confidentiality agreement, is a legal contract where one party shares private business or product information with another party. In return, the second party promises not to share this information with anyone else for a set period.

NDAs help protect important business information and ideas by clearly stating what must stay private and what can be shared.

Usually, NDAs are signed at the start of a business relationship. They can cover any type of confidential information, such as test results, system details, customer lists, or sales numbers. If someone breaks the NDA and leaks information, it is considered a violation of the contract.

  • Bilateral NDA: Both parties share confidential information and agree to protect each other’s data
  • Multilateral NDA: Three or more parties share information, ensuring mutual confidentiality
  • Employee NDA: Employers use this to safeguard business information shared with employees

Purpose of a Non-Disclosure Agreement

An NDA serves as a legal safeguard to protect sensitive data in a professional relationship. It ensures confidentiality and trust between parties.

  • Protects business model: Safeguards unique strategies and processes from competitors

  • Secures trade secrets: Ensures proprietary data remains confidential

  • Prevents information misuse: Limits unauthorised use of shared knowledge

  • Supports partnerships: Facilitates secure collaboration between businesses

  • Avoids legal disputes: Clearly outlines confidentiality terms to prevent misunderstandings

Parts of a Non-Disclosure Agreement

An NDA comprises several essential components to define the scope and enforce confidentiality. These parts ensure legal and practical protection.

  • Definition of confidential information: Specifies what constitutes protected information

  • Exclusions from confidentiality: Lists data not covered under the agreement

  • Obligations of parties: Defines responsibilities for safeguarding information

  • Term and termination: Specifies duration and conditions for ending the NDA

  • Intellectual property rights: Covers copyright, patent, and trademark protections

Information protected with a Non-Disclosure Agreement

  • Business strategies: Marketing plans, expansion initiatives, and financial projections

  • Client information: Customer lists and contact details

Exclusions to NDAs

An NDA cannot cover information that is already publicly known or considered common knowledge. There may be some debate about what counts as public knowledge, but in general, if the information is already available, it cannot be kept secret under an NDA.

Also, if the information becomes public later without the fault of the recipient, or if it relates to illegal activities, it cannot be protected by an NDA.

Additionally, if the recipient already knew the information before signing the NDA, or if they could have found it through independent research or received it legally from someone else, it cannot be treated as confidential under the agreement.

What Are the Consequences of Violating a Non-disclosure Agreement?

You may face the consequences mentioned in the contract if you break a non-disclosure agreement. It is not usually considered a crime, but it can be if it involves something serious, such as stealing trade secrets.

If a person breaks a non-disclosure agreement, they may be taken to court. This can lead to a financial penalty, losing their job, or having to return an asset. They may also face legal action for violating intellectual property rights, such as copyright infringement or failing to act in the best interest of a company. A court may order them to pay financial damages and legal costs. In business environments where sensitive financial details are disclosed—such as during MSME loan applications—NDAs help protect proprietary data from misuse or exposure.

What Is the Duration of an NDA?

Each non-disclosure agreement is different, so the duration can vary. In most cases, it lasts between one year and 10 years, depending on the information that needs to stay private. Some agreements can last forever.

However, for a non-disclosure agreement to be valid in some places, it should not be too vague or unclear. If it is too general, a court may cancel it.

What Is the Cost of an NDA?

The cost of a non-disclosure agreement in India depends on how detailed and complex the agreement is. Preparing one usually costs between Rs. 15,000 and Rs. 1,25,000, which can be managed more easily with financial support such as a secured business loan.

Limitations of an NDA

While non-disclosure agreements can help protect a business, they do have some limitations. These include:

Time period: Most non-disclosure agreements are valid for a fixed time. Once this period ends, you may no longer be legally required to follow the agreement

Scope: A non-disclosure agreement only applies to the specific information mentioned in the document. It is important to clearly define what is covered and what is not before signing. Terms like financial details, trade secrets, and intellectual property should be clearly explained to avoid confusion. If the definitions are too broad, the agreement may not be legally valid

Jurisdiction: Even if an agreement is detailed, its legal strength depends on the laws of the state or country. Some laws limit how enforceable a non-disclosure agreement is, especially if it tries to cover illegal activities. Information that is already public is also usually not protected under a non-disclosure agreement
