Signing for an LLC means acting as its authorized representative; the title on the signature line does not create that authority. Check the operating agreement, written member or manager approval, and any state-specific rules before signing a contract, loan, deed, or government filing. The signature should identify the LLC as the party and accurately state your role.

Quick Summary

  • Confirm that the LLC authorized you to sign this document or transaction.
  • Use the LLC’s exact legal name and your accurate title or representative role.
  • Check the operating agreement, state law, and any required member or manager approval.
  • A signature format does not create authority or cancel a personal guarantee.

How to Format an LLC Signature

Put the LLC’s exact legal name above your signature, then sign your own name and identify the role the company gave you. For example:

Example Company, LLC
By: Jordan Lee
Title: Authorized Manager
Date: [Date]

Follow the form’s instructions for names, titles, witnesses, and notarization. The format identifies whom you represent; it does not authorize a signer who lacks authority.

1. The Name of the LLC

Use the exact legal name shown in the LLC’s formation record or contract so the other party can identify the company. If the LLC uses a DBA, include it when the document asks, while making the legal contracting party clear.

2. Representative Title or Position

Use a title that matches company records, such as “Member,” “Managing Member,” or “Manager.” Do not assume the title itself grants signing authority, and avoid “partner” or “president” unless it accurately describes your role.

Document the Signer’s Authority

Check the operating agreement and state law to learn who can bind the LLC, what approvals a transaction needs, and how the company records them. For a major contract, loan, or property transfer, keep the written approval or delegation with company records.

Rules vary by state. For example, California Corporations Code section 17703.01 distinguishes authority in member-managed and manager-managed LLCs.

When a Power of Attorney Is Needed

A power of attorney is one way to grant signing authority when a separate person or entity delegates it. Check that the written grant covers the signer, document, and transaction, and follow any state or document-specific requirements.

An operating agreement, member or manager resolution, or other written delegation may provide authority instead. Keep the record with the LLC’s company documents.

Who Has Authority to Sign for an LLC?

Organizing collection of documents

Authority may come from state law, the operating agreement, member or manager approval, or a written delegation. The rules differ between member-managed and manager-managed LLCs, so a person’s title alone may not authorize a particular transaction.

Ordinary vendor paperwork, a loan, a deed, and a sale of most company assets may have different approval rules. Check the agreement and any required consent before signing a major transaction.

A registered agent is designated to receive legal papers for an LLC. The California Secretary of State’s service-of-process guide explains that role; the appointment itself does not authorize the agent to sign business contracts.

A representative signature identifies the LLC as the intended party, but it does not settle every personal-liability question. You may still have personal obligations if you sign as an individual or make a separate personal guarantee; the contract and governing law control.

FAQs

Can a Registered Agent Sign Documents of an LLC?

Not merely because the person is the registered agent. The LLC must separately authorize that person for the document or transaction.

How Do I Sign as a Representative of an LLC instead of as an Individual?

Use the LLC’s exact legal name, then sign your name with your accurate title or representative role. Confirm your authority and follow the document’s signature instructions.

What's The Difference Between Signing as an Individual and Signing as a Representative?

No signature format guarantees that result. A representative title can show the capacity in which you signed, but a separate personal guarantee or obligation may still make you personally responsible.
