This Joint Defense Agreement, also called a Common Interest Agreement, is an
agreement whereby multiple parties with a common interest in actual or threatened
litigation can communicate with one another and coordinate strategy. It allows co-
defendants and their lawyers to share work product and information, prepare a joint
strategy, and share costs, without waiving the attorney-client privilege and work product
protection. The sharing may involve cooperation on all aspects of a case, from strategy
to discovery and trial, or it may simply permit access to each other's witnesses.
