The Default Rule: Unanimous Consent

In the absence of a specific provision in your operating agreement, state law almost universally requires the unanimous consent of all existing members to admit a new member to an LLC. This default rule is designed to protect the existing members' right to choose their business partners, a concept known as delectus personae.

Key takeaway: If your operating agreement is silent, do not assume a majority vote is sufficient. You must obtain written consent from 100% of the current members to avoid legal invalidity of the new member's admission.

Action Item: Review your current operating agreement for an 'Admission of Members' section. If it is missing, draft an amendment immediately to define the voting threshold that best suits your business needs.

Why State Statutes Default to Unanimity

LLC statutes are built on the principle of freedom of contract, but they provide default rules for when parties fail to plan. The requirement for unanimity exists because an LLC is a closely held entity. Unlike a corporation, where shares are fungible and ownership is easily transferred, an LLC membership interest often carries management rights and potential personal liability implications.

The RULLCA Standard

Most states have adopted some version of the Revised Uniform Limited Liability Company Act (RULLCA). Under RULLCA, the admission of a new member requires the affirmative vote or consent of all members. This is a strict standard, but it provides a clear baseline that prevents minority members from being forced into a partnership with an unwanted third party.

CaliforniaUnanimous ConsentCal. Corp. Code § 17704.01
New YorkUnanimous ConsentNY LLC Law § 602

Action Item: Verify your specific state's LLC statute. While most align with the table above, some states have nuances regarding whether the 'consent' must be written or if it can be evidenced by the conduct of the members.

Risks of Ignoring Admission Procedures

Failing to follow the correct admission procedure creates significant legal and financial exposure. When a new member is admitted improperly, the following risks arise:

  • Voided Membership: The new member may be legally considered an assignee rather than a member, meaning they have no voting rights.
  • Fiduciary Litigation: Existing members who were excluded from the decision-making process can sue for breach of the operating agreement or breach of fiduciary duty.
  • Tax Reporting Errors: The IRS requires accurate reporting of membership interests. Improper admission can lead to discrepancies in K-1 distributions and potential audits.
  • Deadlock: If a new member is admitted without proper authority, the company may face internal deadlock, making it impossible to pass future resolutions.

Action Item: If you have already admitted a member without a formal vote, execute a 'Ratification Agreement' signed by all original members to retroactively approve the admission and cure the defect.

Drafting for Flexibility

You are not bound by the default unanimous consent rule. You can—and should—customize your operating agreement to reflect your company's operational reality. Common alternatives include:

  1. Majority Vote: Requires 51% or more of the membership interests to approve a new member.
  2. Supermajority Vote: Requires 66% or 75% of the membership interests.
  3. Manager-Managed Admission: Grants the manager(s) the sole authority to admit new members without a member vote.
  4. Right of First Refusal: Allows existing members to purchase the interest before it is offered to a new member, effectively controlling the admission process.

Key takeaway: If you anticipate needing to raise capital or bring in new talent, draft your operating agreement to allow for admission via a majority vote or manager approval to avoid the friction of seeking unanimous consent.

Action Item: Consult with legal counsel to draft an 'Admission of Member' clause that balances your need for control with the need for operational efficiency.
