Professional LLC (PLLC) Operating AgreementLicensure restrictions, malpractice liability that survives the shield, and state-by-state availability

A professional LLC, or PLLC, is an LLC formed by licensed professionals to provide services that require a state-issued license. The structure is required in most states for medical practices, law firms, accounting practices, architecture and engineering firms, and other licensed professions. PLLCs are subject to additional regulatory requirements: ownership is generally restricted to licensed professionals in the same field, the LLC name must indicate the professional designation, and the state licensing board may need to approve formation. Most importantly, the PLLC shield does not protect a member from personal malpractice liability for the member's own professional services.

The summaries below are general legal information, not legal advice. PLLC formation requires coordination with the state professional licensing board for the relevant profession; consult a licensed attorney in your state before forming or restructuring a PLLC.
A.

What a PLLC Protects and What It Doesn't

The most important thing to understand about a PLLC is what it does not protect: a licensed professional member remains personally liable for the member's own professional malpractice. If a physician member of a medical PLLC misdiagnoses a patient, the patient can sue both the PLLC and the physician personally. The physician's personal assets (home, savings, other investments) are at risk, just as they would be if the physician practised as a sole proprietor.

What the PLLC does protect: general business liabilities. If the PLLC's landlord sues over unpaid rent, the claim is against the PLLC only, not against members personally. If an employee sues for wrongful termination, the claim is against the PLLC. If the PLLC's equipment vendor sues over unpaid invoices, the claim is against the PLLC. Members' personal assets are protected from these general business risks just as they would be in a standard LLC.

The PLLC also protects a member from another member's professional malpractice. If Physician A in a two-member medical PLLC commits malpractice, Physician B is not personally liable. The patient can sue the PLLC (collecting from PLLC assets) and Physician A personally, but cannot reach Physician B's personal assets. This protection is the primary reason multi-member professional practices use the PLLC structure rather than partnership.

Liability Shield Coverage Map

Type of ClaimMember Personally Liable?Notes
General business contractsProtectedPLLC shield applies as in standard LLC
Employee claims (wrongful termination, discrimination)ProtectedPLLC shield applies
Lease, equipment, and vendor obligationsProtectedPLLC shield applies
Member's own professional malpracticeNOT protectedMember personally liable; LLC may also be liable but not in lieu of member
Other member's professional malpracticeProtectedNon-acting members not personally liable; only the LLC and the acting member
Negligent supervision of staffPartially protectedMember who failed to supervise may be liable; uninvolved members protected

Because malpractice survives the shield for the acting member, professional malpractice insurance is not optional for PLLC members. Most states require members to maintain minimum coverage as a condition of licensure or PLLC operation.

Sample PLLC Clauses

PLLC Designation and PurposeThe Company is a professional limited liability company organised under the laws of the State of [State] for the purpose of providing [professional services, e.g. medical services / legal services / certified public accountancy services]. The Company shall not engage in any business other than the rendering of professional services in this field and ancillary activities. The Company name shall include the designation "PLLC" or other professional designation required by the State.
Member Licensure RequirementEach Member of the Company must be, at all times, a licensed [profession] in good standing in the State of [State]. A Member who loses or surrenders the license, or who is suspended for more than ninety (90) days, shall immediately cease to be a Member and shall be subject to mandatory buyout under Section [X] of this Agreement at the then-applicable buyout price. A Member becomes "in good standing" again only upon reinstatement of the license without restriction.
Restriction on Ownership TransfersNo Member may transfer all or part of the Member's Membership Interest to any person who is not a licensed [profession] in good standing in the State of [State]. Any attempted transfer to a non-licensed person shall be void. Permitted transfers include transfers to a licensed colleague with the consent of [supermajority/unanimous] of remaining Members and the prior approval of the [State Professional Licensing Board] if required by the State.
Malpractice Insurance RequirementEach Member shall maintain professional malpractice insurance covering the Member's services in not less than the following amounts: $[Per-claim limit] per claim and $[Aggregate annual limit] in the aggregate per year. The Company shall maintain entity-level professional liability insurance in not less than the following amounts: $[Entity per-claim limit] per claim and $[Entity aggregate limit] in the aggregate per year. Failure of any Member to maintain required insurance is a material breach of this Agreement and grounds for immediate involuntary buyout.
Mandatory Buyout on License LossUpon a Member ceasing to be a licensed [profession] in good standing (whether through surrender, suspension exceeding ninety (90) days, revocation, or non-renewal), the Member's entire Membership Interest shall be subject to mandatory buyout by the Company or by the remaining Members. The buyout price shall be the Member's capital account balance plus the Member's pro rata share of undistributed retained earnings, payable over [thirty-six (36)] months from the date of license loss.

State Variations Worth Knowing

California prohibits PLLCs entirely. California-licensed professionals (physicians, attorneys, accountants, etc.) must use a Professional Corporation (PC) or, for some professions, a Registered Limited Liability Partnership (LLP). A non-California licensed professional forming a PLLC in another state and registering to do business in California typically faces difficulty because California does not recognise the structure for in-state services.

New York permits PLLCs (NY LLC Law § 1207). The agreement must be adopted within 90 days of formation (the standard NY rule applies). Ownership is restricted to licensed New York professionals in the same field. The NY publication requirement (NY LLC Law § 206) applies to PLLCs the same as to standard LLCs.

Texas permits PLLCs and uses the term "Professional Limited Liability Company" with the abbreviation "PLLC" or "P.L.L.C." (Tex. BOC § 304.001). Some Texas professions (medicine, dentistry) have specific additional ownership restrictions: ownership must be 100% by licensed professionals in the same field.

Most states require the state professional licensing board to approve PLLC formation, ownership transfers, or member additions. Build the licensing-board approval into the operating agreement as a condition precedent to any membership change.

Five PLLC-Specific Mistakes

Assuming the LLC shield protects against own malpractice

It does not. Members remain personally liable for their own professional malpractice. Only general business liabilities and other members' malpractice are shielded.

Adding a non-professional business partner

Most states prohibit non-professional ownership. A non-professional minority partner can void the PLLC's licensure entirely.

Forgetting state board approval for member changes

Many states require licensing-board approval for ownership transfers or new-member admissions. Skipping this step can void the transfer and trigger licensure issues.

Underinsuring professional malpractice

Insurance is the actual liability layer for the most likely claims. PLLC formation does not reduce the need for high-limit malpractice coverage; it makes coverage more important, not less.

Forming a PLLC in California

California prohibits PLLCs. Use Professional Corporation (PC) or Registered Limited Liability Partnership (LLP) for California-licensed professionals.
