Is an electronic authorization valid?

Yes. Electronic signatures are generally enforceable under the ESIGN Act (15 U.S.C. ch. 96) and UETA in adopting states when intent, consent, attribution, and retention are met.

When is notarization required?

Notarization depends on recipient requirements and state law. Some entities require a notarized or RON-signed authorization before accepting account access.

How do I revoke authority?

Include a revocation clause and notify recipients in writing; follow any recipient-specific procedures and allow time for processing of the cancellation.

What identity proofing is acceptable?

Acceptable methods include government ID upload, in-person verification, SMS or email authentication, and, where required, knowledge-based or credential analysis.

Can an agent sign substitute documents?

Only if the authorization expressly grants substitution authority and the recipient accepts it; otherwise the agent should obtain explicit permission in writing.

How long should records be kept?

Retain executed authorizations per the longest applicable rule: IRS minimums, industry rules (e.g., HIPAA six years), and state variations should guide retention periods.

What a Third Party Authorization Is and when it applies

A Third Party Authorization is a written document by which an individual or organization (the principal) gives another person or entity (the third party or agent) the authority to act on the principal's behalf for specified tasks. Typical uses include allowing a representative to obtain records, make inquiries with service providers, manage accounts, or interact with government agencies. Properly executed authorizations should identify the parties, describe the scope and duration of authority, and include signatures and date. Electronic execution is generally valid under ESIGN (15 U.S.C. ch. 96) and UETA where adopted.

Why a clear Third Party Authorization matters

A concise authorization reduces disputes by documenting who can act, what actions are allowed, and when authority begins and ends. Clear scope limits liability and simplifies verification for banks, insurers, healthcare providers, and utilities.

Who typically completes or relies on a Third Party Authorization

Organizations and individuals use these authorizations when direct access is impractical or when a specialist must act on behalf of the principal.

Business administrators and procurement teams who delegate account management and vendor communications.
Healthcare proxies and authorized medical records designees requesting patient records or billing info.
Legal representatives and paralegals handling filings, case-related communications, or client account access.

Choosing an appropriate signer and documenting identity proofing reduces rejection and speeds processing.

Common signer roles and what they represent

Office Manager

An office manager may sign on behalf of a small business for routine account inquiries, provided the authorization explicitly names the business and the manager and is signed by an authorized company officer.

Patient Representative

A patient representative or authorized designee signs to request medical records; healthcare providers will expect identity verification and a HIPAA-compliant authorization form.

Essential information the form must include

Principal Name: Full legal name

Agent Name: Full legal name or entity

Scope of Authority: Specific actions allowed

Effective Dates: Start and end dates

Identity Proof: ID type and number

Signatures: Signed and dated

Step-by-step: completing a Third Party Authorization

Follow these steps in order to create a clear, enforceable authorization and reduce processing delays.

01

Identify Parties: List principal and agent with full legal names.
02

Define Scope: Specify exact actions, accounts, and limitations.
03

Set Dates: Enter effective and expiration dates in MM/DD/YYYY.

Typical processing flow for an authorization

This sequence shows the normal path from creation to acceptance by a third-party recipient.

Prepare Document: Complete fields and attach supporting ID.
Sign Electronically: Sign by hand or with a compliant eSignature.
Send to Recipient: Deliver to the third party with proof of identity.
Recipient Verification: Recipient confirms identity and accepts authority.

Recommended online workflow settings for authorizations

Configure the signing workflow to balance security and signer convenience.

Field	Configuration
Require ID Upload	Yes, for identity verification
Signer Authentication	Email + SMS code recommended
Audit Trail	Enabled with timestamps and IP
Document Retention	Enable export and long-term storage

Technical considerations for electronic execution

Choose a platform that supports secure eSignatures, audit trails, and required authentication methods.

Authentication: Email, SMS, or KBA options
Integrations: CRM and cloud storage supported
File Formats: PDF and DOCX accepted

Confirm the platform meets any industry-specific legal requirements (for example HIPAA BAA for healthcare) and preserves an auditable record.

Timing to consider when issuing or accepting an authorization

Be aware of effective dates, expiration, and recipient processing time to avoid lapses in authority.

Provide Upon Request:

Give the authorization when the recipient requests proof

Processing Time:

Allow 3–10 business days for verification

Short-Term Authority:

Use explicit end dates for limited actions

Renewal Notice:

Schedule renewal well before expiration

Revocation Lead Time:

Allow time for recipients to process cancellations

Core elements that make a professional Third Party Authorization

Include these elements to ensure clarity, verifiability, and acceptance by recipients across industries.

Clear Parties

Identify principal and agent with full legal names and contact details to avoid ambiguity during verification.

Precise Scope

Describe permitted tasks, account identifiers, or data categories so the agent's authority is narrowly tailored and enforceable.

Effective Period

Set explicit start and end dates or event triggers to limit unintended ongoing authority after tasks are complete.

Identity Proofing

Specify acceptable ID types and any notarization, RON, or authentication requirements expected by the recipient.

Signature and Date

Require dated signatures from the principal and, where appropriate, the agent; include witness or notary blocks as needed.

Revocation Clause

State how the principal can revoke authority and how notice must be delivered to affected third parties.

Data and security controls to capture and retain

Audit Trail: Timestamps and IP

Encryption: TLS in transit

At-rest Protection: AES-256 encryption

Authentication: Multi-factor options

Access Controls: Role-based permissions

Retention Settings: Exportable and archived

Consequences of incomplete or incorrect authorizations

Denied Service: Refusal to act

Liability Exposure: Unauthorized actions

Regulatory Penalty: HIPAA violations possible

Tax Penalties: Incorrect reporting (IRC §6721)

Fraud Risk: Identity fraud exposure

Operational Delays: Processing backlogs

Common mistakes that cause rejection or delay

Vague scope language that leaves recipients unsure what is authorized and leads to refusal.
Mismatched names between the authorization and government ID, causing identity verification failures.
Missing dates or an open-ended effective period that prevents recipients from accepting the document.
No revocation instructions, leaving recipients uncertain how to handle a cancelled authorization.
