Questions
Where do I start?
Head to www.penstead.com/property-authorization-signature, upload your property authorization letter or Spanish carta de autorización de predio/propiedad, add each signer's name and email, and place signature fields for everyone. You get the signed document with a complete audit trail when all signers are done.
What file types work?
PDF, Word documents, and images. Most property authorization letters and cartas de autorización are one of these. Images and scans convert to PDF on upload.
Is it free, and do signers need accounts?
A free account sends 5 signature requests a month. You need that account to send; the people signing need nothing. Pro is $15 a month for 50 requests.
Where is the document stored?
Editing runs in your browser. After you send, the document is stored so signers can open their links, behind an unguessable URL that is not listed or searchable. Signing links expire after 30 days; the completed document stays until you delete it.
What proof do I get that everyone signed?
Every completed document comes with a Certificate of Completion showing who signed, each person's email address, when they opened and signed the document, their IP address, and SHA-256 hashes of the original and signed files. The record is kept after completion.
