How to Securely Sign a Lease Agreement or Contract Online

A complete step-by-step guide to adding a legally valid electronic signature to your landlord lease or client contract for free.

Printing out a lease agreement or contract just to sign it, scan it, and email it back is a time-consuming process. Electronic signatures are legally recognized worldwide and can be completed in under a minute without using paper or ink.

In this guide, we will show you how to securely add your signature to any PDF document for free, ensuring your signature looks professional and clean.

Is an Electronic Signature Legally Binding?

Yes. In most countries, including the United States (via the ESIGN Act and UETA) and the European Union (via eIDAS regulations), electronic signatures hold the same legal weight as traditional handwritten signatures. They are fully acceptable for:

  • Residential and commercial lease agreements.
  • Independent contractor agreements and freelancer contracts.
  • Purchase orders and sales agreements.
  • Nondisclosure agreements (NDAs) and liability waivers.
