How it works

Three steps from PDF to signed.

  1. Upload your PDF.

    Any PDF you already have. Nothing to convert or retype.

  2. Place the signature boxes.

    Drop signature, initials, date and name boxes where they belong, each one color‑coded to the person who fills it in.

  3. They sign from their phone and everyone gets the signed copy.

    Each signer gets a private link by email. When the last person signs, the finished copy goes to everyone.

Why DDA Sign

Everything a signature needs, nothing it doesn’t.

Any document, not just leases

Leases, addenda, agreements, forms: if it’s a PDF, it can be signed.

Signers need no account

No app to install and no password to create. They open the link and sign.

Signed copy plus a completion certificate, automatically

The certificate records who signed and when, attached to the signed PDF.

Optional copies to Google Drive

Turn it on and each completed document is also saved to your Drive. It only touches files it creates.
