Introduction

A signature card records who is authorized to act for a bank account and the signatures or authorization evidence the financial institution uses to recognize those people. It is not a generic company signature sheet. The card connects account authority to a specific bank relationship, so its owner, change process, and storage rules matter as much as the signatures themselves.

What a signature card records

A bank can use a signature card or a comparable account-authority record to capture the legal account holder, authorized signers, roles, and specimen signatures. The exact format and requirements are set by the financial institution and the account agreement. The FDIC consumer resources explain the role of account relationships and bank records; the bank’s own account-opening and authorization documents remain the controlling source for a specific account.

A strong internal record separates three concepts:

Concept	Meaning	Common mistake
Account owner	Entity or person that owns the account	Treating every employee as an owner
Authorized signer	Person permitted to give instructions or sign within the account mandate	Assuming a job title grants bank authority
Internal approver	Person who approves a company action	Assuming internal approval automatically changes bank authority

Keep corporate authority and bank authority aligned

A board resolution, delegation matrix, or internal approval authorizes an employee to act for the company. The bank still needs its own required record and change process before the account authority changes. That separation prevents a dangerous shortcut: sending a signed internal memo to a bank and assuming the signatory list has changed.

When a signer joins, leaves, changes role, or loses delegated authority, start a controlled update. Identify the account, the affected authority, the approving corporate document, the bank form or process, the submission owner, and the final confirmation. Keep the prior and new authority records according to the organization’s retention policy.

Use a controlled workflow for supporting documents

Digital signing is useful for the corporate documents that support a bank-authority change, such as a board resolution, officer certificate, or internal delegation. The eSignature workflow identifies the document version, assign the correct internal approvers, and preserve the completed record. It does not replace the bank’s own mandate, its account-opening requirements, or its verification process.

Nota Sign electronic signature lets teams send, sign, and manage agreements in a secure workspace. That gives finance and legal teams a controlled route to prepare approval documents, collect the required internal signatures, and retain the completed agreement before the bank-specific authorization process begins.

Build a signature-card change checklist

Identify every account affected by the role or authority change.
Confirm the corporate document that authorizes the change.
Obtain the bank’s current required form and submission instructions.
Route internal approval documents to the correct approvers.
Record the date the bank confirms the updated authority.
Remove obsolete signer access through the organization’s bank-administration process.
Retain the completed internal approvals and the bank confirmation together with the authority record.

Avoid specimen-signature record failures

The most common failures are not handwriting problems. They are stale authorization lists, unclear ownership, incomplete board or officer approvals, and a missing confirmation that the bank accepted the change. A finance team needs one accountable owner for the change from start to finish.

For recurring authority changes, create a template that separates the internal approval packet from the bank’s prescribed forms. This lets the team reuse its internal route while still following each bank’s current instructions.

Nota Sign advantages for finance authority-change workflows

For finance authority changes, teams use Nota Sign to run the internal approval packet: prepare the approved document version, assign approver roles, collect signatures, control access, and retain the completed record. For company-issued resolutions, officer certificates, and authorization letters, electronic seals connect legal-entity origin and tamper-evident evidence to the document.
