Startup Legal Basics: What You Need Before You Launch
LLC vs C-Corp, state of incorporation, IP protection, essential contracts, and when to hire a lawyer — the legal checklist every founder needs.

Most founders treat legal setup as a bureaucratic chore — something to rush through so they can get back to building. This is a mistake that costs real money. A survey by the Kauffman Foundation found that startup legal issues (co-founder disputes, IP ownership gaps, improper incorporation) were a contributing factor in 23% of startup failures. The legal foundation you set in the first weeks determines your options for years to come.
You do not need to become a legal expert. But you do need to understand the key decisions, their tradeoffs, and when to bring in a professional versus handling something yourself.
Entity Selection: LLC vs. C-Corp
This is the first legal decision most founders face, and it has cascading implications for taxes, fundraising, equity compensation, and exit options.
The C-Corporation
A C-Corp is the standard structure for venture-backed startups. There are practical reasons:
VC compatibility. Venture capital funds are structured to invest in C-Corps. Most VC term sheets assume C-Corp governance, preferred stock issuance, and board structures that LLCs cannot easily replicate. If you plan to raise institutional capital, incorporate as a C-Corp.
Stock options. C-Corps can issue incentive stock options (ISOs) under Section 422 of the Internal Revenue Code, which gives employees favorable tax treatment. LLCs can issue equity-like interests, but the tax implications are more complex and less favorable for employees.
Scalability. C-Corp governance is well-understood by investors, acquirers, and lawyers. If your goal is a large exit (IPO or acquisition), the C-Corp structure makes due diligence and deal execution smoother.
The downside: double taxation. C-Corps pay corporate income tax on profits, and then shareholders pay personal income tax on dividends. For profitable, privately held companies that distribute earnings, this creates a meaningful tax burden. However, most early-stage startups are not profitable and reinvest all revenue, making double taxation a theoretical concern rather than a practical one.
The LLC
An LLC (Limited Liability Company) is the better choice for businesses that may not raise venture capital and want simpler tax treatment.
Pass-through taxation. LLC profits and losses flow through to members' personal tax returns, avoiding double taxation. For a profitable consulting firm, agency, or e-commerce business, this saves real money.
Flexibility. LLC operating agreements can be customized extensively. Profit-sharing arrangements, management structures, and member rights can be tailored to your specific situation.
Simplicity. Less paperwork, fewer governance requirements, and lower maintenance costs than a C-Corp. No board of directors required. No annual shareholder meetings.
The downside: investor friction. Most VCs will not invest in an LLC. Converting from LLC to C-Corp later is possible but involves legal fees ($5,000-15,000), potential tax consequences, and negotiation of new governance documents. If you think VC funding is possible in your future, start as a C-Corp.
The Decision Framework
- Raising VC or issuing stock options? C-Corp.
- Bootstrapping a profitable business? LLC.
- Unsure? Start as a C-Corp in Delaware. It is easier to convert a C-Corp to a structure with pass-through taxation (via S-Corp election) than to convert an LLC to a C-Corp.
State of Incorporation
Why Delaware Dominates
More than 65% of Fortune 500 companies are incorporated in Delaware through the Delaware Division of Corporations. More than 90% of VC-backed startups incorporate there. The reasons are structural, not geographical:
Established case law. Delaware's Court of Chancery has over 200 years of corporate law precedent. When disputes arise, the outcomes are more predictable than in states with less-developed corporate jurisprudence.
Business-friendly statutes. The Delaware General Corporation Law is widely regarded as the most flexible corporate statute in the US. It allows extensive customization of governance structures, stock classes, and board arrangements.
Investor expectation. VCs expect Delaware incorporation. Deviating creates friction during due diligence. Some investors will require you to reincorporate in Delaware before they invest — adding cost and delay.
No state income tax on out-of-state revenue. If you are incorporated in Delaware but operate elsewhere, you owe no Delaware state income tax on revenue generated outside Delaware.
When Not to Use Delaware
If you are forming an LLC for a local service business, incorporating in your home state is simpler and cheaper. Delaware incorporation adds a registered agent fee ($100-300 per year) and requires you to register as a foreign entity in your operating state (another filing and another fee). For small, local businesses, the complexity outweighs the benefit.
How to Incorporate
Services like Stripe Atlas ($500), Clerky ($799+), and Firstbase ($399+) handle Delaware incorporation with startup-friendly document templates. They will file your Certificate of Incorporation, create bylaws, issue initial stock, and generate board consents. The process takes 1-3 weeks.
If you have co-founders and need a customized equity split, vesting schedules, or IP assignment — use Clerky or a startup lawyer. The templated services are designed for standard configurations and may not handle complex co-founder arrangements well.
Intellectual Property Protection
IP Assignment
Every founder and every employee or contractor who contributes to the product must sign an IP assignment agreement. This document transfers ownership of all work product to the company. Without it, a departed co-founder, a fired contractor, or even a freelance designer could claim ownership of code, designs, or content they created.
The IP assignment should be signed before any work begins. Retroactive assignments are possible but legally weaker. Include this in your co-founder agreement and in every employment and contractor agreement.
Trademarks
File a federal trademark application for your company name and logo once you have settled on them. Trademark registration costs $250-350 per class through the USPTO (you can file yourself) or $1,000-2,000 through an attorney.
Common mistakes: choosing a name that is too generic to trademark, not searching existing trademarks before committing to a name, and not filing early enough. A trademark application establishes your priority date — the earlier you file, the stronger your claim.
Patents
For most software startups, patents are expensive ($10,000-20,000+ per patent), slow (2-4 years for approval), and of limited defensive value. Provisional patent applications ($1,600 filing fee) can establish a priority date while you evaluate whether a full patent application is worthwhile.
File patents if you have a genuinely novel technical invention that creates a defensible competitive advantage. Skip them if your advantage comes from execution, network effects, or brand — patents will not help.
Trade Secrets
Some IP is better protected as a trade secret than as a patent. Coca-Cola's formula, Google's search algorithm, and KFC's recipe are all trade secrets. Protection requires three things: the information has economic value from being secret, you take reasonable steps to keep it secret (NDAs, access controls, employee agreements), and you have not publicly disclosed it.
Essential Contracts
Terms of Service and Privacy Policy
If you have a website or app, you need both. They are not optional — privacy regulations (GDPR, CCPA, state-level laws) require a privacy policy, and your terms of service define the legal relationship with your users.
Do not copy another company's terms. Use a service like Termly ($10-15 per month) or Iubenda to generate compliant documents tailored to your product. If you collect sensitive data (health information, financial data, children's data), consult a privacy attorney.
Customer Contracts
For B2B products, you need a Master Service Agreement (MSA) or a SaaS subscription agreement. This covers pricing, payment terms, service level commitments, liability limitations, termination rights, and dispute resolution.
Key clauses to get right:
- Limitation of liability: Cap your liability at the fees paid in the prior 12 months. Without this, a single customer dispute could bankrupt your company.
- Indemnification: Define who is responsible for what. The customer indemnifies you against claims arising from their use of the product. You indemnify the customer against IP infringement claims.
- Termination and data portability: Define what happens to customer data when the relationship ends. Customers increasingly demand data export capabilities as a contractual right.
Contractor Agreements
Every contractor (designer, developer, writer, consultant) needs a signed agreement covering scope of work, payment terms, IP assignment, confidentiality, and termination provisions. Do not rely on verbal agreements or email threads.
The most critical clause for startups: IP assignment. Without it, the contractor may retain ownership of the work they create — even if you paid for it. Under US copyright law, work created by an independent contractor belongs to the contractor unless there is a written assignment.
When to Hire a Lawyer
Do It Yourself
- Filing incorporation documents through Stripe Atlas or Clerky
- Generating standard terms of service and privacy policies through template services
- Filing trademark applications through the USPTO (straightforward for standard word marks)
- Setting up a simple LLC for a solo business
Hire a Startup Lawyer
- Drafting co-founder agreements with non-standard equity splits or vesting
- Negotiating your first VC term sheet
- Handling IP disputes or cease-and-desist letters
- Navigating industry-specific regulations (fintech, healthcare, education)
- Reviewing or drafting enterprise customer contracts above $50K ACV
- Any situation where you think "I am not sure if this is legal"
Finding Affordable Startup Legal Help
Startup-focused firms like Cooley, Goodwin, Gunderson Dettmer, and Wilson Sonsini offer deferred-fee arrangements for funded startups. Some will defer legal fees until your Series A closes, knowing that the ongoing relationship is worth the initial investment.
For earlier stages, platforms like LegalZoom, Rocket Lawyer, and Atrium provide standardized documents at lower cost. Local bar associations often have referral programs with reduced-rate initial consultations.
Budget $3,000-10,000 for initial legal setup (incorporation, co-founder agreement, IP assignments, basic contracts). This is one of the most cost-effective investments you will make — fixing legal mistakes after they compound is 10-50x more expensive.
Common Legal Mistakes Founders Make
Not incorporating before starting work. If you and your co-founder build a product before incorporating, IP ownership is ambiguous. Incorporate first, then assign all prior work to the company.
Misclassifying employees as contractors. The IRS, state labor departments, and courts are aggressive about worker classification. If someone works regular hours, uses your equipment, and follows your direction, they are an employee — regardless of what your contract says. Misclassification penalties include back taxes, overtime, and benefits.
Ignoring cap table management. From day one, track who owns what. Use a tool like Carta, Pulley, or even a carefully maintained spreadsheet. A messy cap table creates chaos during fundraising, when investors demand clear ownership records.
Verbal equity promises. Never promise equity verbally. If it is not in a signed document with vesting terms, it does not exist — and someone who believes it does will eventually sue you.
Skipping the operating agreement (LLC) or bylaws (C-Corp). Default state rules govern your company if you do not have these documents. Default rules are often not what you want. Customize your governance documents to match your actual intentions.
Conclusion
Legal setup is not exciting, but it is foundational. The decisions you make about entity structure, IP protection, and contracts in the first weeks of your company create the framework for everything that follows — fundraising, hiring, partnerships, and eventual exit.
Start with the basics: incorporate (Delaware C-Corp for VC track, home-state LLC for bootstrapping), sign IP assignments with every contributor, set up standard contracts, and get a co-founder agreement in place. Budget $3,000-10,000 for legal setup and use startup-friendly services to keep costs manageable. And when something feels uncertain, hire a lawyer — the cost of prevention is always less than the cost of cure. With the legal foundation solid, you can focus your energy on what matters: building the product and finding customers.
