Sign Any Document
Online — Legally & Fast

How online document signing works — and why it's legally binding

An electronic signature is any digital mark a person applies to a document to indicate their intent to agree. Under the U.S. Electronic Signatures in Global and National Commerce Act (ESIGN) and the Uniform Electronic Transactions Act (UETA), electronic signatures carry the same legal weight as ink signatures — provided there is clear intent to sign, consent to do business electronically, and a reliable record of the transaction. Zignature satisfies all three requirements for every document processed on the platform.

Every signed document on Zignature generates a tamper-evident audit trail that captures the signer's email address, IP address, timestamp, and device information at the moment of signing. This audit certificate is embedded directly into the completed PDF and is retrievable at any time from your dashboard. If a signed agreement is ever questioned in a dispute, the audit trail provides the court-admissible evidence needed to enforce it.

Different document types call for different signing setups. An NDA between two parties needs two signature fields, a date, and nothing else. An employment contract might require initials on each page, a full signature block, and a separate acknowledgement for an attached handbook. A real estate lease could have multiple signers on different timelines, with the landlord countersigning after the tenant. Zignature's template builder handles all of these patterns — custom field placement, ordered signing sequences, and conditional routing — so the right person receives the right document at the right time.

Templates save the most time for documents your team sends repeatedly. Build the template once, define all the signature and form fields, and every future send is a matter of seconds. Bulk send lets you dispatch the same document to hundreds of recipients simultaneously — ideal for annual policy acknowledgements, mass consent forms, or investment round closings. For documents created on the fly, the drag-and-drop builder lets anyone upload a PDF and add signature fields in under a minute.
