There is no open source software dedicated to contract management. Nevertheless, many open source ECM solutions can be used for such case due to their low cost and great versatility.
For pure contract management, we would recommend Alfresco or Nuxeo 5.

Alfresco is the first open source enterprise-scale document management system that includes a modern content repository, an out-of-the-box portal framework for managing and using content designed to work with standard portals, and a groundbreaking Common Internet File System (CIFS) interface that provides Microsoft Windows file system compatibility.
