Are DocuSend signatures legally binding? +
Yes. DocuSend electronic signatures comply with the ESIGN Act (US federal), UETA (US state), and eIDAS (EU). The audit trail — including IP address, timestamp, email verification, and document hash — provides the evidentiary record required for enforceability.
Can signers sign on mobile? +
Yes. The signer interface is fully mobile-optimized. Signers can draw their signature with a finger on any touchscreen device. No app download is required — signing happens entirely in the mobile browser.
What document formats does DocuSend accept? +
DocuSend accepts PDF files only. If your document is in Word, Excel, or another format, convert it to PDF first. The maximum file size is 25MB. DocuSend does not modify the original document content — signature fields are overlaid on the existing PDF.
How long are completed documents stored? +
Completed documents are stored for the duration of your subscription. Enterprise plans include configurable retention periods (1–10 years). All documents are encrypted at rest with AES-256.
