Legal Definitions - common-interest doctrine

The common-interest doctrine is a legal principle that allows parties with a shared legal interest to share privileged information without waiving their right to attorney-client privilege. This means that if two or more parties are involved in a legal matter and share a common legal interest, they can share information with each other and their attorneys without fear of waiving their right to keep that information confidential.

For example, if two companies are involved in a lawsuit and have a common legal interest in the outcome, they can share information with each other and their attorneys without waiving their right to attorney-client privilege. This allows them to work together to build a stronger case and avoid any potential conflicts of interest.
