Getting Started with Startup Legal Basics

Learn the essential legal foundations every startup needs β€” from incorporation and equity agreements to intellectual property and compliance. Get it right early to avoid costly mistakes later.

Overview

Legal work is not the most exciting part of building a startup, but getting the basics right early saves enormous headaches and costs down the road. The core legal foundations for most startups include incorporating as a Delaware C-Corp (if you plan to raise venture capital), setting up proper equity agreements between co-founders, protecting your intellectual property, and ensuring your terms of service and privacy policy are in order. You do not need to become a lawyer, but you do need to understand the key decisions and when to involve legal counsel. Most startup-friendly law firms offer deferred fee arrangements for early-stage companies, so cost should not be a reason to skip proper legal setup.

Key Concepts to Understand

Delaware C-Corp

The standard incorporation structure for venture-backed startups in the US. Delaware offers well-established corporate law, a business-friendly court system, and is what most investors expect. Incorporating as a C-Corp (rather than an LLC) is necessary if you plan to issue stock options or raise institutional funding.

Founder Vesting

An agreement where co-founders earn their equity over time (typically four years) rather than receiving it all upfront. Vesting protects the company and remaining founders if someone leaves early. Without it, a co-founder who leaves after three months could walk away with a large chunk of the company.

IP Assignment Agreement

A legal document that ensures all intellectual property created by founders, employees, and contractors belongs to the company, not to the individuals. Investors will require this during due diligence, and failing to have it can delay or kill a fundraise.

83(b) Election

A tax election that founders and early employees file with the IRS within 30 days of receiving restricted stock. It lets you pay taxes on the stock's current (low) value instead of its (potentially much higher) future value when it vests. Missing the 30-day deadline can result in a significant tax bill.

Terms of Service and Privacy Policy

Legal agreements between your company and your users. Terms of service define the rules for using your product and limit your liability. A privacy policy describes how you collect, use, and protect user data. Both are legally required in most jurisdictions and should be in place before your product launches.

Your First Steps

1

Incorporate your company

If you plan to raise venture capital, incorporate as a Delaware C-Corp. You can do this through an online formation service or a startup law firm. You will need to choose a company name, appoint initial directors, and issue founder shares. Budget 500 to 2,000 dollars depending on the service you use.

Set up founder vesting agreements

All co-founders should have vesting schedules, even if you trust each other completely. The standard is four-year vesting with a one-year cliff. Use a standard form from your law firm or a formation service. File your 83(b) elections within 30 days β€” this deadline is absolute and cannot be extended.

3

Ensure IP assignment is in place

Have every founder, employee, and contractor sign an IP assignment agreement that transfers ownership of any work product to the company. This is especially important if any work was done before incorporation. Investors will check for this, and gaps can be deal-breakers.

4

Draft your terms of service and privacy policy

Use a startup-friendly legal template as a starting point, then have a lawyer review it. Your privacy policy must comply with GDPR if you have European users and CCPA if you have California users. Do not launch your product without these in place β€” the legal exposure is not worth the time saved.

5

Find a startup-friendly law firm

Look for firms that specialize in venture-backed startups and offer deferred fee arrangements. A good startup lawyer will have seen hundreds of companies at your stage and can help you avoid common pitfalls. Ask other founders for referrals β€” personal recommendations are the most reliable way to find good counsel.

Common Mistakes to Avoid

Skipping the 83(b) election after receiving restricted stock

File your 83(b) election with the IRS within 30 days of receiving restricted stock. Send it by certified mail and keep proof of mailing. Missing this deadline can result in hundreds of thousands of dollars in unnecessary taxes if your company becomes valuable.

Not having vesting agreements between co-founders

Without vesting, a co-founder who leaves after one month owns the same equity as someone who stays for years. This creates resentment, complicates future fundraising, and can make it hard to attract a replacement. Set up vesting before you write a line of code.

Using generic legal templates without legal review

Templates are a good starting point but should always be reviewed by a lawyer who understands your specific situation. A few hundred dollars of legal review now can prevent lawsuits, regulatory fines, or failed fundraising rounds later.
