What is a Limited Liability Partnership (LLP)?

TL;DR: An LLP is a specific type of partnership used almost exclusively by high-risk, licensed professionals like lawyers and accountants. It operates like a General Partnership (where all partners actively manage the firm), but it provides a "partial" corporate veil. It protects you from the personal debts and malpractice of your other partners, but it does NOT protect you from your own malpractice.

Introduction: The Partnership Problem for Lawyers

Historically, law firms and accounting firms were organized as General Partnerships. This was incredibly dangerous. Under a General Partnership, all partners have Joint and Several Liability.

Imagine a law firm with 50 partners. Partner #49 makes a terrible mistake and commits legal malpractice, costing a client $10 million. Under a General Partnership, the client could sue Partner #1 (who had nothing to do with the case), and seize Partner #1's personal house to pay the $10 million.

This terrifying reality led to the creation of the Limited Liability Partnership (LLP) in the early 1990s, specifically designed to protect licensed professionals from each other.

How an LLP Works (The Partial Shield)

The LLP offers a unique liability shield that is "partial" or "hybrid." It was designed to fix the Joint and Several Liability problem without letting professionals escape their own bad behavior.

1. Protection from Your Partners' Malpractice

This is the primary reason LLPs exist. In an LLP, you are generally not personally liable for the negligence, malpractice, or wrongful acts committed by the other partners in the firm. If your partner botches a multi-million dollar lawsuit, the client can sue the firm, and sue your partner, but they cannot seize your personal savings.

2. NO Protection from Your Own Malpractice

This is the critical caveat. An LLP will never protect you from your own professional negligence. If you are the lawyer who botches the multi-million dollar lawsuit, your personal assets are completely exposed. (This is why every professional in an LLP carries massive Malpractice Insurance).

3. Protection from General Business Debts (Varies by State)

The level of protection against general business debts (like a commercial lease or a vendor invoice) varies significantly depending on the state.

• "Full Shield" States (e.g., New York, California): The LLP acts like a corporation. Partners are completely protected from all general business debts. If the firm goes bankrupt, the landlord cannot sue the partners personally for unpaid rent.
• "Partial Shield" States: The LLP only protects partners from each other's malpractice. For general business debts, the partners remain jointly and severally liable. If the firm can't pay rent, the landlord can sue the partners personally.

Who Can Form an LLP?

In many major states (like California and New York), you cannot form an LLP to run a restaurant or a tech startup. State laws restrict the use of LLPs exclusively to state-licensed professionals, most notably:

• Lawyers
• Certified Public Accountants (CPAs)
• Architects

LLP vs. LLC: What is the Difference?

If an LLC provides complete liability protection, why do law firms use LLPs?

1. State Restrictions: In states like California, licensed professionals are legally forbidden from forming an LLC. They must choose between a Professional Corporation (PC) or an LLP.
2. Tax Structure: Historically, the LLP structure was easier to integrate with the traditional "eat what you kill" partnership tax structures of massive law firms compared to the corporate structures of PCs.

Conclusion

The LLP was invented to save the modern mega-law firm. It allows hundreds of high-risk professionals to work together under one brand name without living in constant fear that a colleague in another city will make a mistake that ruins them financially.
