Legal Doc Vault allows you to replace the outdated method of emailing unsecured file attachments by using our simple File Vault feature. File Vault allows you to securely upload, store, and retrieve files. Additionally, our system allows you to track user, date, and other useful information about your documents. Once files are uploaded to File Vault, the organized list of files (or “file tree”) can double as an index that is searchable and printable.
