Can a Virtual Assistant Sign for You? Electronic Signatures and Delegated Authority

Published September 23, 2026.

Delegated signing authority and electronic signatures

Delegated signing authority is the power a business gives a person, including a virtual assistant, to sign or approve documents on its behalf. Electronic signature law is a separate question. The federal Electronic Signatures in Global and National Commerce Act and the state Uniform Electronic Transactions Act decide whether an electronic signature or record is legally effective. Agency law decides whether the person using that signature had the right to bind the business. A founder can get the first right and still create a dispute on the second by assuming that a signed contract is binding because the signature is valid. This review separates the two questions and describes the written authority that keeps a delegated approval workflow enforceable.

Why validity and authority are different questions

Electronic signature statutes are about form. They say that a signature or record may not be denied legal effect solely because it is electronic. They do not say that any electronic signature binds any party. The person who signs still needs authority, and the business can still argue that an assistant exceeded the scope of the assignment. A document signed by an assistant with no authority is not rescued by the fact that it was signed electronically.

The separation has practical value. A business can adopt a robust electronic signature tool and still be exposed if it never defined what the assistant may sign. Conversely, a business can define authority clearly and then use a basic electronic signature method within the law. The controls belong on the authority side, because that is where delegation creates risk. The tool is a convenience. The authority is the decision.

The ESIGN Act and the Uniform Electronic Transactions Act

The ESIGN Act provides that a signature, contract, or other record relating to a transaction in or affecting interstate or foreign commerce may not be denied legal effect solely because it is in electronic form. It also allows an electronic record to satisfy a requirement that information be in writing, with important conditions when a consumer must receive the record. When a statute or regulation requires a consumer to receive a written record, the consumer must consent electronically, the business must give a clear statement of the hardware and software requirements, and the consumer must be able to withdraw consent. The consent requirement is the part most often missed.

The Uniform Electronic Transactions Act is a model state law that most states have adopted, and it applies to transactions where the parties have agreed to conduct them electronically. The state law and the federal law operate together, and a business should confirm which applies to a particular transaction and state. Both laws contain exceptions. Documents such as wills, certain family law instruments, and some court papers are outside their scope, and notarized or acknowledged documents can require additional steps. The Internal Revenue Service publishes its own electronic signature guidance for the tax forms it accepts, which is a reminder that a federal agency can have requirements beyond the general rule.

How authority to sign is created

Authority to sign comes from agency law rather than from the signature statute. Express authority is granted directly, such as a written statement that the assistant may sign vendor agreements up to a stated amount. Implied authority is the power reasonably necessary to carry out the task the assistant was given, such as signing a routine receipt for a delivery the assistant was told to manage. Apparent authority arises when the business's conduct leads a third party to reasonably believe the assistant may act, which is why a job title and a signature block can mislead a vendor.

A business can reduce the risk by making authority express and written. The document should name the assistant or the role, describe the categories of agreements that may be signed, set any dollar or commitment limits, and state what is reserved to the owner. It should also say how the assistant identifies the capacity in which the assistant signs, for example as an authorized representative of the company. If a third party is led to believe the assistant has broader power than was granted, the business may still be bound or may face a claim based on the appearance of authority.

What should stay with the owner

Some decisions carry consequences that a general delegation should not reach. Commitments that are unusual in size or duration, equity or ownership changes, settlements of claims, guarantees and personal guarantees, leases, and anything that touches regulated filing obligations usually belong with the owner or a named officer. Delegating these without a clear written authority and a confirmation step is the pattern most likely to produce a dispute about whether the business is bound.

Our review of segregation of duties in delegated financial tasks explains why the person who approves a payment should not also control the record that hides it, a principle that applies to signing authority as well.

Documenting and auditing delegated authority

The written authority should live with the business's records, not in a personal inbox. It should be dated, signed by an officer, and reviewed when the assistant's role changes or the engagement ends. When the assistant signs, the record should show the basis of authority, the date, and the agreed scope. A delegation log that lists each signed document, the authority relied on, and where the executed copy is stored gives the business a clean answer if a vendor later questions the signature.

Confirmation steps matter as much as the authority memo. A short rule that any agreement above a set amount requires a written approval before signature prevents an assistant from having to guess. A periodic review of what was signed, against the authority limits, catches drift. The employment or contractor relationship also affects how the business should document the role, a point examined in our review of virtual assistant classification and employment status.

Common gaps

Three gaps appear most often. The first is an assistant who has been signing for months under an informal understanding that no one wrote down. The second is a signature block that describes the assistant as a manager, which can create apparent authority beyond what was intended. The third is reliance on an electronic signature tool without checking the agency rules that apply to the document, including the consumer consent requirement and the statutory exceptions. Each is fixable with a short written authority, an approval threshold, and a records practice.

Methodology and limits

This review examined the Electronic Signatures in Global and National Commerce Act, the consumer consent provisions of that Act, the Federal Trade Commission's material on the statute, the Uniform Law Commission's Electronic Transactions Act, and the Internal Revenue Service electronic signature guidance. Each source was checked on September 23, 2026. This review provides a general framework. It does not provide legal advice, does not determine whether a particular signature binds a particular party, and does not cover every state or document exception. Agency and electronic signature outcomes depend on the specific facts and the governing law, so a business should confirm its position with qualified counsel.

Frequently asked questions

Is an electronic signature as valid as a handwritten one? Yes for most transactions, because the ESIGN Act and state law give electronic signatures the same legal effect. Narrow categories are excluded, and consumer records carry extra consent conditions.

Can my virtual assistant sign contracts for my company? Only within the authority the business grants. Put the scope, the limits, and the reserved decisions in a signed authority document.

Does a valid electronic signature prove the signer had authority? No. Validity is about form. Authority comes from agency law, so both questions must be answered.

What about tax forms and notarized documents? Government agencies and notarization rules can require specific methods, and some documents fall outside the general electronic signature laws. Confirm the rule for each document type.
