Form 503 General Information Assumed Name Certificate
Use a Form 503 General Information Assumed Name Certificate template to make your document workflow more streamlined.
What Form 503 means
Form 503 General Information Assumed Name Certificate records the relationship between a business owner and an assumed business name. The filer enters the owner’s identifying information, the assumed name, and the required filing details, then signs and submits the certificate through the responsible state or local office. It does not create a separate legal entity or replace formation documents. A completed copy helps businesses show which legal owner operates under the name used on contracts, invoices, accounts, and customer communications. Filing requirements and public-record procedures depend on the applicable Secretary of State or county authority.

Form 503 filing challenges
Entering an assumed name that differs from the version used on contracts creates inconsistent business records and review delays. Using the owner’s trade name instead of the legal owner can obscure who is responsible for the certificate. Submitting a signed PDF without confirming the responsible filing office can leave the assumed-name registration incomplete. Editing owner or name fields after signing can make the stored copy differ from the submitted certificate.
Form 503 troubleshooting questions
Resolve field, signature, audit-trail, security, and filing-office issues before relying on a completed Form 503 certificate.
Upload the original Form 503 PDF to signNow, then review the automatically detected fields. If a field is missing or misplaced, add or reposition it manually before sending. The sender remains responsible for confirming that every owner and assumed-name entry matches the filing copy.
A signer can complete Form 503 with a typed or drawn electronic signature when the transaction permits electronic signing. ESIGN and applicable UETA rules generally recognize electronic signatures, but the responsible filing office may impose separate submission or notarization requirements.
Use signNow’s audit trail to review signer identity, timestamps, actions, and completion history. Export the signed document and certificate of completion together, then compare the final assumed name and owner information with the filing record.
The signNow Business plan is listed at $8 per user per month with annual billing. Paid plans include 100 signature invites per user per year; Business Premium adds bulk send when many Form 503 certificates use the same workflow.
SignNow encrypts data in transit with TLS 1.2/1.3 and at rest with AES-256. Its compliance framework includes ESIGN and UETA support, SOC 2 Type II certification, and ISO 27001 certification; legal filing requirements still come from the responsible state authority.
A signNow workflow prepares and signs the document, but it does not determine where Form 503 must be filed or whether a county copy is required. Confirm submission instructions with the applicable Secretary of State or county filing office.
