FAQs About inserting signatures

Answers to common problems and setup questions when placing a digital signature on an Adobe PDF using signNow, including authentication, file handling, and signature validation.

• How do I insert a signature into an Adobe PDF using signNow?
  Upload your PDF to signNow, open the document editor, drag a Signature field to the required location, save the document, then either Sign Now to apply your signature or Send for Signature to other recipients; the platform captures an audit trail automatically for legal evidence.
• Why can’t a signer see the signature field?
  Confirm the field is assigned to the correct recipient role and placed on the visible page; check signer permissions, ensure the PDF isn’t password-protected, and verify the signer uses a supported browser or the mobile app to view and complete fields.
• What authentication options are available for signers?
  signNow supports email verification, SMS one-time codes, and optional third-party identity checks depending on plan level; enforce stronger authentication for sensitive Adobe PDFs to improve legal defensibility and reduce fraud risk.
• How do I validate the eSignature after signing?
  Download the signed PDF and review its embedded audit trail and signature certificate; check timestamps, signer email, and cryptographic markers included by signNow to verify signature integrity and authenticity.
• What if the PDF changes after signing?
  Any post-signing modification breaks the document’s signature integrity; signNow stores the original signed version and flags tampering, providing tamper-evident audit records for legal review and dispute resolution.
• How do I request a signer to re-sign or correct a field?
  Use the document management options to void or decline and resend the PDF with corrected fields, or use the edit workflow to create a new version and send a fresh signature request to maintain a clear audit trail.

Best practices for signing PDFs

Follow these operational best practices when inserting digital signatures into Adobe PDFs to reduce errors and maintain legal defensibility.

Prepare clean source PDFs

Start with a finalized Adobe PDF that has consistent margins and no extraneous layers; flatten complex elements and ensure fields are placed on the topmost layer so signers see and interact with fields reliably during signing.

Use templates for repeat documents

Create reusable templates for commonly used Adobe PDFs to ensure field consistency, reduce manual placement errors, and speed up bulk sends; templates also help ensure that mandatory fields are not missed.

Enforce appropriate authentication

Select SMS codes or higher-assurance identity checks for sensitive agreements; require signer acknowledgment and capture IP and timestamp data to strengthen the evidentiary record.

Maintain retention and access logs

Set document retention policies aligned with corporate and legal requirements, archive executed Adobe PDFs with audit trails, and restrict access to signed documents through role-based permissions and secure cloud storage.
