Relation Sign is a Nordic e-signature service from Relation Labs in Norway. Upload a PDF or fill in a ready-made contract template, and send it for signing with Norwegian BankID, Swedish BankID, Danish MitID, Finnish eID or a one-time code by SMS or e-mail. Every signed document is sealed as a PAdES PDF, so anyone can verify afterwards who signed and that nothing has changed.
Businesses pay per signature with no subscription, and get templates with their own branding, reminders, a shared contact list, folders, confidential signings and SharePoint archiving. Developers can integrate through a REST API, webhooks and an MCP server for AI agents. Private persons can also send contracts for signing without a business account.
