Corporate Service Requirements Guide
How to properly serve corporations, LLCs, and other business entities. Registered agent requirements by state, common mistakes, and best practices for legal professionals.
Serving corporations and business entities is fundamentally different from serving individuals. Business entities have specific legal requirements for service of process that must be followed precisely to ensure valid service. Improper corporate service is a leading cause of dismissed lawsuits and wasted legal expenses.
This comprehensive guide covers everything attorneys and legal professionals need to know about serving corporations, LLCs, partnerships, and other business entities—including registered agent requirements, acceptable service methods, and state-specific rules.
Part 1: Understanding Corporate Service
Why Corporate Service is Different
Unlike individuals, corporations are legal entities that cannot physically receive documents. Service must be made to authorized representatives who can accept service on behalf of the entity.
Key Differences:
- Designated Representatives: Service must be to registered agent, officer, director, or managing agent—not any employee
- Location Requirements: Service address may be different from business operating address
- Verification Necessary: Must verify current registered agent and authorized representatives before service
- State-Specific Rules: Each state has different requirements for corporate service
- Entity Status Matters: Must verify entity is active and in good standing
Critical Warning
Service on a receptionist, security guard, or general employee is invalid in most jurisdictions. The person served must have actual authority to accept service on behalf of the corporation. Invalid service can result in case dismissal and statute of limitations problems.
Part 2: Business Entity Types and Service Requirements

Conclusion
Corporate service is a specialized area of process serving that requires thorough research, attention to detail, and knowledge of entity-specific requirements. The stakes are high—improper corporate service can result in case dismissal, wasted litigation expenses, and potential malpractice claims.
The key to successful corporate service is verification. Always verify the current registered agent, confirm the entity is active, and ensure the person accepting service has proper authority. Document every step of your research and use professional process servers who understand corporate service requirements.
When in doubt about proper service procedures for a specific entity type or jurisdiction, consult with an experienced attorney or professional process server. The time invested in proper research and verification is always less than the cost of invalid service and having to start over.
