Contracts are the backbone of every business relationship. Whether you’re closing a deal with a client, hiring a contractor, onboarding a vendor, or entering a partnership, the agreements you sign determine your rights, obligations, and risk exposure. Yet many businesses, especially startups and fast-growing companies, unintentionally make legal mistakes that can lead to disputes, financial losses, or unenforceable rights.

As business lawyers at TOS Lawyer, we regularly review contracts that contain avoidable errors, loose language, or missing clauses. These issues rarely appear harmful in the moment, but they can become significant liabilities later. To help founders protect their companies, we’ve compiled ten expert tips based on common problems we encounter in real-world agreements.

1. Define Every Key Term Clearly

Ambiguity is the most common cause of contract disputes. Words like “deliverables,” “completion,” “support,” “proprietary information,” or “payment schedule” must be defined explicitly. If there’s room for interpretation, there’s room for conflict.

Expert Insight: A contract lawyer ensures all critical terms are defined in the definitions section, removing ambiguity before it becomes a legal issue.

2. Don’t Rely on Copy-Paste or Online Templates

Generic templates are not tailored to your business model, state laws, or risks. Many founders copy contracts from competitors or use free online forms that don’t match their operations or jurisdiction.

Expert Insight: Templates rarely address industry-specific legal requirements and often miss key protections. Custom drafting prevents the hidden risks templates create.

3. Specify Payment Terms and Consequences

Unclear payment terms cause immediate financial problems. Agreements should detail billing dates, late fees, refund conditions, prorations, and acceptable payment methods.

Expert Insight: A lawyer ensures your payment structure aligns with your financial model, especially for SaaS, subscription, or milestone-based services.

4. Clarify Termination and Exit Clauses

Every contract eventually ends. If termination terms aren’t clear, both parties may dispute ownership of money, data, or deliverables.
Essential elements include:

  • Notice periods
  • Termination for convenience vs. cause
  • Obligations upon termination
  • Final payment rules

Expert Insight: A lawyer establishes fair, enforceable exit terms that minimize conflict.

5. Address Intellectual Property (IP) Ownership Early

IP ownership disputes can shut down a business. This applies to software, branding, creative content, product designs, and code created by employees, contractors, or partners.

Expert Insight: IP clauses must specify what is owned, what is licensed, and what rights survive termination. For tech companies, this is non-negotiable.

6. Include Governing Law and Jurisdiction Clauses

If a dispute arises, where will it be resolved? Which state’s laws apply?
Without clear governing law and venue clauses, parties can be dragged into expensive out-of-state litigation.

Expert Insight: A simple clause designating your home state’s laws can reduce costs and increase predictability.

7. Limit Liability and Use Indemnification Properly

Without liability limitations, you may become responsible for damages disproportionate to your role in a project.
Key protections include:

  • Caps on damages
  • Exclusion of certain types of damages (like lost profits)
  • Clear indemnification provisions

Expert Insight: These clauses protect your business from excessive claims and shift responsibility where appropriate.

8. Ensure Compliance with Privacy and Data Protection Laws

Any contract involving personal data, customer lists, emails, usage data, analytics, or triggers legal obligations under GDPR, CCPA, and other privacy frameworks.

Expert Insight: Contracts should include data processing, retention, breach response, and cross-border transfer clauses. Privacy compliance cannot be an afterthought.

9. Document Amendments and Verbal Agreements Properly

Many disputes arise because parties make verbal changes or send informal emails that contradict the main contract.

Expert Insight: A lawyer ensures amendment procedures are formalized, meaning all changes must be documented and signed to be valid.

10. Always Have a Qualified Business Lawyer Review Before Signing

The most critical tip: never sign a contract your lawyer hasn’t reviewed.
What feels like a minor oversight today could become a costly dispute tomorrow. A legal review is far cheaper than litigation, renegotiation, or losing ownership rights.

Expert Insight: A lawyer sees issues you may never notice, vague clauses, hidden liability, missing protections, or unenforceable terms.
