Why Sign Disclosure Agreements with SigPDF?

Disclosure agreements exist to control how sensitive information is shared and protected. Whether you are signing a non-disclosure agreement before a business negotiation, a financial disclosure for a regulatory filing, or a property disclosure in a real estate transaction, these documents contain information that demands privacy.

SigPDF is built for exactly this scenario. Your disclosure agreement PDF is processed entirely in your web browser. The document is never uploaded to any server, never stored in a third-party database, and never accessible to anyone other than you. Open the document, sign it, and download your signed copy — all in under a minute.

Types of Disclosure Agreements You Can Sign

  • Non-disclosure agreements (NDAs) — mutual and one-way
  • Confidentiality agreements
  • Financial disclosure statements
  • Property and seller disclosure forms
  • Lead-based paint disclosure forms
  • Conflict of interest disclosure forms
  • HIPAA privacy notice acknowledgments
  • Investor and SEC disclosure documents
  • Employee invention and IP disclosure agreements
  • Government security clearance disclosure forms

Privacy Is Essential for Disclosure Documents

The irony of signing a confidentiality agreement on a cloud-based platform is hard to miss. You are agreeing to protect sensitive information while simultaneously uploading that information to a third-party server. The agreement itself may reference trade secrets, proprietary technology, financial terms, or personal information that should remain confidential.

With SigPDF, this contradiction disappears. Your disclosure agreement stays on your device throughout the entire signing process. No data is transmitted, no copies are stored remotely, and no third party ever sees the contents of your document.

Legal Validity of E-Signed Disclosure Agreements

  • United States — ESIGN Act & UETA: Electronic signatures on NDAs, financial disclosures, and other disclosure documents are legally enforceable for commercial and consumer purposes.
  • European Union — eIDAS Regulation: Simple electronic signatures have legal effect across all EU/EEA member states, including on confidentiality and disclosure agreements.
  • UK, Canada, Australia: Each has legislation recognizing electronic signatures on business and legal documents, including disclosure agreements.

Frequently Asked Questions

Are electronically signed disclosure agreements legally binding?
Yes. Under the ESIGN Act (US) and eIDAS Regulation (EU), electronic signatures on disclosure agreements carry the same legal weight as handwritten signatures. Both parties must consent to electronic signing, which is standard practice in modern business.
What types of disclosure agreements can I sign with SigPDF?
SigPDF works with any disclosure agreement in PDF format — non-disclosure agreements (NDAs), financial disclosure forms, property disclosure statements, conflict of interest disclosures, HIPAA disclosures, investor disclosures, and any other document requiring a signature.
Is my confidential information safe with SigPDF?
Yes. SigPDF processes your PDF entirely in your web browser. Disclosure agreements often contain sensitive trade secrets, financial data, or personal information — none of this is ever uploaded to any server. The file stays on your device throughout the signing process.
What is the difference between a disclosure agreement and an NDA?
A disclosure agreement is a broad term covering any document where parties agree to share or protect information. An NDA (non-disclosure agreement) is a specific type of disclosure agreement that prevents parties from sharing confidential information. Both can be signed electronically with SigPDF.
Can I sign disclosure forms for real estate transactions?
Yes. Property disclosure statements, lead-based paint disclosures, seller disclosure forms, and other real estate disclosure documents can all be signed with SigPDF. These are standard PDF documents that work seamlessly with the SigPDF editor.
How much does SigPDF cost for signing disclosure agreements?
SigPDF costs from €2.08/month billed annually, with unlimited document signatures. Sign one disclosure agreement or a hundred — the price stays the same. No per-document fees, no envelope limits, and no per-signature charges.
Can I sign disclosure agreements on my phone or tablet?
Yes. SigPDF works in any mobile browser on iPhone, iPad, and Android. Open SigPDF in Safari or Chrome, load the disclosure PDF, draw or type your signature, and download the signed document — no app required.
