What Is a Signatory? Authorized Signatories, Signature Blocks, and Who Can Sign

A signatory is a person or legal entity that signs a document or agreement, either directly or through an authorized representative. In business contracts, the signatory may sign for themselves or on behalf of a company, provided they have authority to do so. The signature block records who signed and in what capacity.

What Is a Signatory?

A signatory is a party that signs an agreement or other document to show approval, acceptance, or consent. When the signatory is an individual acting personally, the answer is straightforward. The person signs their own name.

Business agreements can be different. A company, LLC, nonprofit, partnership, or other legal entity cannot physically place a signature on a document. An individual signs on its behalf.

For example, if a contract is between ABC Company and XYZ Company, the companies may be the parties to the agreement while an authorized representative from each organization actually signs it.

This matters because the person placing the signature may not be entering the contract personally. Their signature can instead show that they are acting for the organization named in the agreement.

Once all required signatures and other execution requirements have been completed, the agreement may become an executed contract. Exactly when that happens depends on the contract language and any other requirements that apply.

Signatory vs. Signer vs. Signee

These terms overlap, but they are not always used in exactly the same way.

‍

In everyday business use, signer and signatory are often used interchangeably. The difference becomes more useful when a legal entity is involved. A corporation may be the signatory to the contract, while an officer or other authorized person is the individual signer acting for that corporation.

Because signee is used less consistently, contracts and workflow instructions are usually clearer when they identify the party and the signer directly.

What Is an Authorized Signatory?

An authorized signatory, sometimes called an authorized signer, is someone who has authority to sign a document on behalf of another person or organization.

In a company setting, that means the person has been given sufficient authority to enter the organization into the particular transaction.

Authority is not determined by job title alone in every situation. It may come from the organization's governing documents, internal resolutions, delegated authority, a power of attorney, or another valid source.

The exact requirements depend on the type of organization, the transaction, and applicable law.

Who Can Sign on Behalf of a Company?

There is no universal list of job titles that can sign every agreement for every business.

Depending on the company's structure and internal rules, authorized signatories might include senior officers, directors, managers, partners, members, employees with delegated signing authority, or agents specifically appointed for a transaction.

For example, a CEO may have broad authority for ordinary contracts while a department manager may only be authorized to approve agreements below a certain value. A procurement lead might be permitted to sign vendor agreements but not financing documents.

For that reason, seeing a title such as "Vice President" or "Manager" in a signature block does not by itself establish the scope of that person's authority.

Federal procurement rules provide one example of how authority may be addressed in a specific context. For U.S. federal contracts, 48 CFR § 4.102 states that a corporate contract is signed in the corporate name, followed by "by," the signature, and the title of the person authorized to sign. The rule also requires the contracting officer to ensure that the individual has authority to bind the corporation.

Those rules apply to that specific federal contracting context. Businesses should determine the requirements that apply to their own organization and transaction.

How to Confirm Signing Authority

Before an important agreement is signed, the parties should know whether the person signing for an organization actually has authority to do so.

Depending on the transaction, confirmation may involve reviewing the company's bylaws or operating agreement, a board or member resolution, an internal delegation-of-authority policy, a power of attorney, or other evidence showing who is permitted to sign and within what limits.

It can also help to confirm the individual's current title, the type and value of the agreement, and whether the organization requires another approval before signature.

For higher-value or unusual transactions, a counterparty may request written evidence of authority rather than relying solely on the individual's title.

There is no single verification method that applies to every company or jurisdiction. Organizations should establish their own approval process and seek legal advice where the authority to sign is uncertain.

What Is a Signature Block?

A signature block is the section of a document where a person signs and where information about the signer and their capacity is recorded. It can show more than the signature itself. It can identify who signed, which organization they represented, their title, and the date of signature.

That context becomes particularly important when someone signs for a business. A well-structured signature block helps distinguish between an individual signing personally and an individual signing as an authorized representative of a company.

Signature blocks commonly appear at the end of contracts, master service agreements, purchase agreements, vendor agreements, employment documents, and other agreements that require formal approval.

Signature Block Format

For an individual signing personally, a simple signature block might look like this:

Individual

Signature: __________________________

Name: Jordan Lee

Date: ______________________________

For a company, the organization should be clearly identified along with the individual signing on its behalf:

ABC COMPANY, INC.

By: ________________________________

Name: Jordan Lee

Title: Chief Financial Officer

Date: ______________________________

Here, ABC Company, Inc. is the contracting party. Jordan Lee is the individual signer, and "Chief Financial Officer" identifies the capacity in which Jordan is signing.

If two organizations are signing the same agreement, each would normally have its own signature block:

ABC COMPANY, INC.

By: ________________________________

Name: Jordan Lee

Title: Chief Financial Officer

Date: ______________________________

XYZ SERVICES LLC

By: ________________________________

Name: Taylor Morgan

Title: Managing Member

Date: ______________________________

The appropriate format may vary depending on the entity, agreement, and jurisdiction. These examples illustrate structure only and are not legal templates.

Common Signature Block Mistakes

Common issues include:

• Leaving out the legal name of the company the person represents
• Failing to identify the signer's title or capacity
• Having someone sign personally when the agreement is intended to bind an entity
• Using a job title without confirming that the person has authority for that transaction
• Providing too few signature blocks for the parties that must sign
• Placing signature fields where it is unclear which party they belong to
• Forgetting a required witness, date, or other execution field

A clear signature block does not create signing authority on its own. It records how the person is signing. The authority must come from the appropriate organizational or legal source.

Documents With Multiple Signatories

Many agreements require more than one signatory. A contract might need signatures from two companies. An internal approval may require both a department head and an executive. A transaction might require several parties to sign before the agreement is complete.

Multiple signatories can sign sequentially, in parallel, or through a combination of both approaches. 

With sequential signing, one signer completes their part before the agreement moves to the next person. This can be useful when one approval depends on an earlier signature.

With parallel signing, several signers can receive the document at the same time and complete their parts independently.

For example, a customer could sign first, followed by an authorized company representative who countersigns. In another workflow, two business partners might both receive the agreement at the same time.

The agreement should make clear who must sign and whether every required signature must be collected before the document is treated as fully executed.

Managing Signatories in Blueink

Blueink provides several tools for organizing agreements that involve one or more signatories.

Signer roles help identify who is responsible for each part of a template. Instead of treating every participant as an unnamed signer, teams can assign roles that reflect the workflow, such as Customer, Company Representative, Manager, or Approver.

For agreements with several people, signing order lets senders control how the envelope moves between signers. Blueink supports sequential signing, parallel signing, or a combination of both, which can help when one authorized signatory needs to sign before another. Learn more about how to set signing order in Blueink.

Where a document requires another person to witness a signature, Blueink also supports a dedicated witness role. Depending on the workflow, the witness can be nominated in advance or as part of signing.

For transactions that need an additional identity check, Blueink supports signer authentication options such as SMS PIN, driver's license verification, and selfie verification. Authentication can add another layer of confidence that the intended person accessed the signing request, but it does not determine whether that person has legal authority to bind an organization.

After signing, Blueink's Certificate of Evidence provides a separate record of the transaction. It can help distinguish the activity of different participants when an agreement has multiple signers.

These tools help manage the signing workflow, but the sender remains responsible for identifying the correct parties and determining who is authorized to sign.

Frequently Asked Questions

What Is a Signatory?

A signatory is a person or legal entity that signs an agreement or other document. When a company is the contracting party, an authorized individual typically signs on its behalf.

The signatory may therefore be the person signing personally or the organization represented by an authorized signer, depending on how the term is being used.

Who Can Sign a Contract on Behalf of a Company?

A person with sufficient authority from the company can sign on its behalf.

That authority may come from governing documents, corporate or member resolutions, delegated authority, a power of attorney, or another valid source. A person's title alone does not establish authority for every transaction.

The rules depend on the organization, agreement, and applicable law.

What Is the Difference Between a Signer and a Signatory?

A signer is usually the individual who applies a physical or electronic signature. A signatory is the party that signs or becomes a signing party to the agreement. In many transactions they are the same person. When someone signs for a company, however, the company may be the signatory while the authorized representative is the individual signer.

What Is a Signature Block?

A signature block is the part of a document that records the signature and information identifying the signer. For a company agreement, it commonly includes the company's legal name, the representative's signature, their printed name, title, and the signature date.

Can a Contract Have More Than One Signatory?

Yes. Contracts often have two or more signatories. Each party that needs to sign should have a clearly identified place to do so. Depending on the workflow, the parties may sign in a specific sequence or at the same time.

The agreement itself should identify whose signatures are required before it is considered complete.

Does a Signature Block Prove Someone Is Authorized to Sign?

No. A signature block shows who signed and the capacity they claimed to be acting in, but it does not by itself establish that the person had authority to bind the organization.

Signing authority should be confirmed through the appropriate company records, delegation, or other evidence applicable to the transaction.
