Small Business Legal Checklist: 15 Must-Have Documents
Most small businesses are under-documented. Not because the owners don't care, but because building the product, finding customers, and running operations takes every available hour. Legal paperwork waits.
The problem: you only discover which documents you're missing when something goes wrong. By then, the cost is much higher than the cost of having them in place.
This checklist covers the 15 legal documents every small business should have, what each one does, and where to get them.

Why Documentation Matters
Written agreements prevent disputes. When roles, compensation, and expectations are on paper:
- Courts can enforce them
- Partners can't "remember" different terms
- Customers can't claim you promised something you didn't
- Employees know exactly what's expected
The flip side: missing documentation creates specific, predictable problems:
- No NDA → former employees or partners can take your trade secrets
- No client contract → clients dispute scope, timelines, and payment
- No privacy policy → you're non-compliant with state privacy laws and risk regulatory fines
- No employee handbook → inconsistent policies create discrimination and wrongful termination exposure

Entity Formation Documents
1. Articles of Incorporation or Organization
What it is: The foundational document filed with your state to legally form a corporation (Articles of Incorporation) or LLC (Articles of Organization).
Why you need it: Without this, your business isn't a legal entity. You personally own everything and are personally liable for all debts.
Where to get it: File directly with your state's Secretary of State. Cost: $50–$500 depending on state. Delaware is the most popular state for incorporation due to its business-friendly court system.
2. Operating Agreement (LLC) or Bylaws (Corporation)
What it is: Internal governance document that defines how the business is managed, how decisions are made, and how profits are distributed.
Why you need it: Most states don't legally require an operating agreement, but it protects your LLC status (preventing courts from "piercing the corporate veil") and prevents default state rules from applying.
Where to get it: Attorney, LegalZoom, or a free generator.
3. EIN Confirmation
What it is: Your Employer Identification Number from the IRS — the business equivalent of a Social Security Number.
Why you need it: Required to open a business bank account, hire employees, file business taxes, and apply for business credit.
Where to get it: Free at IRS.gov — takes 5 minutes online.

Customer and Vendor Contracts
4. Client Service Agreement
What it is: A contract between your business and clients that defines the scope of work, deliverables, payment terms, timelines, and what happens if things go wrong.
Why you need it: Without a written contract, disputes over scope ("that wasn't included"), payment ("I thought that was free"), and ownership ("I own everything you made") are impossible to win cleanly.
Must include: Scope of work, payment terms, late payment penalties, IP ownership, limitation of liability, dispute resolution.
Where to get it: Service Contract Generator
5. Non-Disclosure Agreement (NDA)
What it is: A contract that prevents the other party from disclosing your confidential information — business plans, trade secrets, customer lists, financial data.
Why you need it: Before sharing sensitive information with partners, vendors, investors, or employees — even in informal conversations — an NDA protects you.
Types: Unilateral (one party's information is protected), Mutual (both parties' information is protected).
Where to get it: NDA Generator
6. Independent Contractor Agreement
What it is: A contract between your business and a freelancer or contractor defining the work, compensation, IP ownership, and their status as an independent contractor (not an employee).
Why you need it: Misclassifying employees as contractors triggers penalties from the IRS and state labor boards. The contractor agreement documents the independent nature of the relationship.
Must include: IC status clause, IP work-for-hire assignment, payment terms, non-solicitation clause.
Where to get it: Contractor Agreement Generator
7. Master Service Agreement (MSA)
What it is: A framework contract with a long-term vendor or client that governs the overall relationship. Individual projects are handled with Statements of Work (SOWs) that reference the MSA.
Why you need it: Avoids re-negotiating standard terms (liability, IP, confidentiality) for every new project with recurring clients.

Employment and Contractor Documents
8. Employment Agreement
What it is: A contract between employer and employee defining role, compensation, benefits, confidentiality obligations, and termination procedures.
Why you need it: Establishes clear expectations, protects confidential information, and defines grounds for termination — reducing wrongful termination exposure.
Where to get it: Employment Agreement Generator
9. Employee Handbook
What it is: A company policy manual covering workplace conduct, benefits, leave policies, anti-harassment policies, disciplinary procedures, and termination.
Why you need it: Required for certain federal compliance (FMLA, OSHA, anti-discrimination). Provides consistent application of policies. Creates a defense against discrimination claims.
What to include: Code of conduct, anti-harassment and discrimination policy, leave policies (PTO, FMLA, sick leave), compensation and benefits overview, social media policy, termination procedures.
Note: For businesses with 15+ employees, an anti-discrimination policy is legally required under Title VII. For 50+ employees, an FMLA policy is required.
10. Offer Letter
What it is: A formal written offer of employment that precedes the employment agreement. Sets out the role, compensation, start date, and key conditions.
Why you need it: Creates a record that the employee was informed of all material terms before accepting. Avoids later disputes over promised compensation or benefits.
---
Website and Privacy Documents
11. Privacy Policy
What it is: A legal disclosure on your website explaining what personal data you collect, how you use it, and how users can control their data.
Why you need it: Required by law in California (CCPA), Virginia, Colorado, and most of the EU (GDPR) if you collect data from residents there. Google and Apple also require a privacy policy for apps. Violations can result in $7,500 per intentional violation under CCPA.
Must include: What data you collect, why you collect it, who you share it with, user rights (access, deletion), contact information.
Where to get it: Privacy Policy Generator
12. Terms of Service
What it is: A contract between your business and users of your website or app that defines acceptable use, limits your liability, and establishes dispute resolution.
Why you need it: Protects you from liability for user-generated content, misuse of your platform, or claims that your service caused harm.
Where to get it: Terms of Service Generator

Intellectual Property Protection
13. IP Assignment Agreement
What it is: A document in which an employee or contractor assigns all intellectual property they create in the course of their work to your company.
Why you need it: Without this, contractors own the work they create for you. This is a major issue when building software, creative work, or any proprietary asset. The IP assignment clause should be in your contractor agreement and employee agreement, but a standalone IP assignment agreement adds a clear record.
14. Trademark Registration
What it is: Federal registration of your business name, logo, or slogan with the USPTO.
Why you need it: Trademark registration gives you nationwide rights to your brand and the ability to sue infringers. Without it, you have common law rights only in your geographic area — making national enforcement nearly impossible.
How to file: USPTO.gov — DIY filing costs $250–$350 per class. Attorney-assisted: $800–$1,500+. Expect 8–12 months to registration.
---
Financial Documents
15. Promissory Note
What it is: A written promise to repay a loan, with specific terms for interest and repayment schedule.
Why you need it: Any time you lend or borrow money — from a bank, investor, or partner — a promissory note creates an enforceable legal record.

Frequently Asked Questions
Which legal document should I create first?
If you're a brand new business, prioritize entity formation (Articles of Organization/Incorporation + operating agreement/bylaws + EIN). These protect your personal assets from business liabilities. After formation, the next most critical document depends on your business model: client service agreement for service businesses, independent contractor agreement if you use freelancers, and a privacy policy if your website collects any user data.
Do I need all 15 documents from day one?
No. Prioritize based on your current situation. A solo freelancer just starting out needs: client service agreement, NDA, and privacy policy. A business with employees needs to add employment agreements and an employee handbook. A business with a product/brand building equity needs trademark registration and IP assignment agreements. Add documents as your business complexity grows.
Can I use free templates for all of these?
Yes, with caveats. Free templates work well for standard documents (NDAs, service agreements, privacy policies). They're less suitable for complex situations: businesses in heavily regulated industries (healthcare, finance), businesses with significant IP value, or documents that are highly customized to your specific terms. When stakes are high — major client contracts, equity arrangements — invest in an attorney.
What's the difference between a service agreement and a contract?
Nothing — they're the same thing. "Service agreement," "client contract," "engagement letter," and "statement of work" all refer to written agreements between parties to provide services. The terminology varies by industry. Law firms use "engagement letters." Consultants use "consulting agreements." Creative agencies use "client contracts." All are enforceable contracts if they contain the essential elements.
How often should I review my legal documents?
Annually at minimum, and whenever: your business model changes significantly, you hire employees (triggers employment document needs), you expand to new states (different privacy laws, different non-compete enforceability), you raise outside capital, or you bring on a significant new type of client or vendor relationship.
