Short answer: a signature block is the part of a contract that shows who is agreeing and in what capacity the person signs. When you sign for a business, the block names the company first. You then sign on a “By:” line, with your printed name and title underneath. That layout tells everyone that the company is the party, not you personally. Get it wrong and you can end up arguing about whether the company is bound, or whether you are.
Below are copy-ready signature block templates for the situations small businesses run into most. They cover signing as an individual, for an LLC, for a corporation, for an LLC whose manager is another company, as an agent and as a trustee. We also cover signature pages, counterparts and how all of this works when the contract is signed electronically.
What is a signature block?
A signature block (also called a signature line or execution block) usually sits at the end of a contract. It follows a closing line such as “IN WITNESS WHEREOF, the parties have executed this Agreement as of the Effective Date.” It has up to five parts:
- The party’s legal name, exactly as registered, for example “Northwind Studio LLC”.
- A jurisdiction line for entities, for example “a Delaware limited liability company”. It helps identify the entity when several share similar names.
- The signature line, introduced by “By:” when someone signs on behalf of an entity.
- Name and Title, printed, so a reader can tell who signed and why that person had authority.
- Date, optional when the contract has an Effective Date, but useful as a record of when each party actually signed.
The block does not create authority by itself. It records the capacity in which someone signs. Whether that person was actually allowed to sign comes from the company’s documents, which we cover below.
Signature block templates you can copy
Replace the sample names with your own. Keep the capitalization of the party name consistent with the rest of the contract.
1. Individual (freelancer, sole proprietor, consumer)
JORDAN LEE Signature: ______________________ Date: ___________________________
No “By:” and no title. You are the party, so you are personally bound. A sole proprietorship is not a separate legal entity. A sole proprietor using a trade name can sign as “Jordan Lee, doing business as Lee Design”. A freelancer who has formed an LLC should use the LLC block instead. Otherwise the LLC’s liability protection may not apply to that contract.
2. LLC (member-managed or manager-managed)
NORTHWIND STUDIO LLC, a Delaware limited liability company By: ______________________ Name: Mark Reeves Title: Managing Member Date: ____________________
Common titles are “Member” or “Managing Member” in a member-managed LLC and “Manager” in a manager-managed LLC. Some LLCs also appoint officers such as a CEO or President. Use whatever title your operating agreement actually gives you, because that is where your authority to sign comes from.
3. Corporation (Inc., Corp.)
ACME ANALYTICS, INC., a Delaware corporation By: ______________________ Name: Dana Brooks Title: Chief Executive Officer Date: ____________________
Officers such as the CEO or President usually have authority to sign ordinary business contracts. Unusual or high-value deals are different: selling the business, large loans, real estate. For those, the other side may ask for a board resolution or a secretary’s certificate confirming the signer’s authority. Shareholders and directors do not sign for the corporation simply because they hold that role.
4. Nested block: an LLC managed by another company
Holding structures are common: a project LLC is managed by a parent company, and a person signs for the parent. The block shows each layer so the chain of authority is clear.

Who is bound: the entity or the person?
This is the question the signature block exists to answer. When the block names the company and you sign “By:” with your title, you are signing as the company’s representative. The company is the party to the contract.
When the company name is missing and you sign with only your name, a court may have to decide whether you meant to sign personally. That is exactly the kind of dispute small business owners formed an LLC or corporation to avoid. The opposite mistake happens too: a business owner signs a personal guarantee but the block lists only the company, leaving the guarantee open to challenge.
If you are signing in two capacities, for example for the company and as a personal guarantor, use two separate blocks and sign twice.
| Who signs | Party line | Signature line | Title | Where authority comes from |
|---|---|---|---|---|
| Individual | Your full legal name | Signature | None | You |
| LLC member or manager | LLC name + state | By: | Member, Managing Member, Manager | Operating agreement, state LLC law |
| Corporate officer | Corporation name + state | By: | CEO, President, other officer | Bylaws, board resolution |
| Parent company signing for an LLC | LLC name, then parent “its Manager” | Nested By: | Officer of the parent | Both companies’ documents |
| Agent | Principal’s name | By: agent, as attorney-in-fact | Attorney-in-fact | Power of attorney |
| Trustee | Trust name + date | By: | Trustee | Trust instrument |
The 7 most common signature block mistakes
- Wrong entity name. “Northwind Studios” instead of “Northwind Studio LLC”. Copy the name from your state registration, including the suffix.
- Missing “By:” and title. A bare signature under the company name can look like a personal signature.
- The signer lacks authority. A sales manager signing a five-year lease may not bind the company. For big contracts, ask the other side to confirm authority in writing.
- Party names that do not match the preamble. The contract’s opening paragraph and the signature blocks should name the same entities, written the same way.
- Signature block alone on the last page. A page with only signatures can be detached and reused. Add “[Signature page to Master Services Agreement]” at the bottom, or keep a line of contract text on the same page.
- Inconsistent dates. When parties sign on different days, rely on a defined Effective Date, and let each block record its own signing date.
- Counterparts that never come back. If each party signs a separate copy, make sure you collect every signed copy and keep them together. A counterparts clause (below) makes this valid; good tracking makes it provable.
Signature pages and counterparts
Most commercial contracts include a counterparts clause such as:
“This Agreement may be executed in counterparts, each of which is deemed an original and all of which together constitute one agreement. Signatures delivered electronically, including through an electronic signature service or by PDF, are deemed original signatures for all purposes.”
The first sentence lets each party sign its own copy. The second confirms that the parties agree to sign electronically, which removes any later argument about the format.
How signature blocks work with electronic signatures
In the US, the federal ESIGN Act (15 U.S.C. §7001) says a signature or contract cannot be denied legal effect solely because it is in electronic form. At state level, the Uniform Electronic Transactions Act (UETA) has been adopted by 49 states, the District of Columbia and the U.S. Virgin Islands; New York has its own equivalent, the Electronic Signatures and Records Act (ESRA). For most business contracts, an e-signature is as valid as ink.
The block itself does not change. You still name the entity, show “By:”, and print the signer’s name and title. What changes is how the signature line gets filled:
- Place a signature field on each “By:” line, assigned to the right signer, and a date field next to it.
- Type the printed name and title into the document before sending, so the signer only signs and the block cannot be filled in inconsistently.
- Set the signing order when it matters, for example your client signs first and your company countersigns.
- Keep the audit trail with the signed document. It records who signed, when, from which email address and IP address, which is the electronic equivalent of a witness to the signature.
A few document types fall outside ESIGN and UETA or need extra formalities. Examples include wills and testamentary trusts, adoption and divorce documents, court orders and certain consumer notices (utility shut-offs, foreclosure or eviction, insurance cancellation). Documents that must be notarized or witnessed follow those specific rules. For everyday contracts like an NDA, a master service agreement, an independent contractor agreement or a statement of work, electronic signing is standard practice.

Frequently asked questions
What should a signature block include?
For a business: the entity’s exact legal name, its state of formation, a “By:” signature line, the signer’s printed name and their title. For an individual: the person’s full name, a signature line and usually a date.
How do I sign a contract on behalf of my LLC?
Write the LLC’s full legal name and state. Then sign on the “By:” line and print your name and your title, such as Member, Managing Member or Manager. That shows you are signing for the LLC, not personally.
Can I be personally liable if I sign incorrectly?
You can be exposed. If the block does not name the company or show your representative capacity, the other party may argue that you signed personally. Always use the company name, “By:” and your title.
Is a signature block required for a contract to be valid?
No law requires a specific format, but a clear block is the best evidence of who agreed and in what capacity. Without it, disputes about who is bound become much harder to resolve.
Do electronic signatures work with signature blocks?
Yes. Under the ESIGN Act and UETA, an e-signature placed on the “By:” line has the same legal effect as ink for most business contracts. The block’s text stays the same; the e-signature tool records who signed and when in an audit trail.
What does “its Managing Member” mean in a signature block?
It appears in nested blocks when one company acts for another. It means the company named on that line is signing as the managing member of the entity above it. The person signing below acts for that managing member.
