To sign an NDA, read it thoroughly to understand what information you must keep confidential, verify the parties and duration, then add your signature electronically or by hand and return it to the other party. The ESIGN Act and UETA make electronic signatures legally valid for NDAs.
Key Takeaway: Read the NDA carefully before signing. Pay attention to what's defined as confidential, how long obligations last, and what exceptions exist. You can sign NDAs electronically—e-signatures are fully valid for these agreements.
What Is an NDA?
Basic Definition
A Non-Disclosure Agreement (also called a confidentiality agreement) is a legal contract where one or more parties agree not to disclose certain information.
Types of NDAs
| Type | Description | Common Use |
|---|---|---|
| Unilateral (One-Way) | One party shares, other protects | Job interviews, vendor discussions |
| Bilateral (Mutual) | Both parties share and protect | Business partnerships, M&A |
| Multilateral | Multiple parties involved | Complex deals, joint ventures |
Before You Sign: What to Review
1. Definition of Confidential Information
| Review Point | What to Check |
|---|---|
| Scope | What's actually covered? |
| Specificity | Is it clearly defined or overly broad? |
| Marking requirements | Must info be labeled "confidential"? |
| Exclusions | What's NOT confidential? |
Red flag: Vague definitions like "all information shared" without reasonable limitations.
2. Standard Exclusions
Most NDAs should exclude:

| Prior knowledge | You already knew it |

3. Duration of Obligations
| Term | Typical Range |
|---|---|
| Agreement term | 1-5 years |
| Confidentiality period | 2-5 years after term ends |
| Trade secrets | Often indefinite |
Red flag: Perpetual obligations for non-trade-secret information.
4. Permitted Uses

5. Return/Destruction Requirements
| Requirement | Consideration |
|---|---|
| Return all materials | Can you comply? |
| Destroy copies | Including backups? |

6. Remedies and Liability
| Term | What to Check |
|---|---|
| Injunctive relief | Standard—allows court orders |
| Damages | What you could owe if you breach |
