Written by attorneys · grounded in primary & secondary sources — see below
Multiple clients who retain the same attorney to advise them on a shared legal matter. Communications among the clients and the lawyer remain privileged against outsiders but lose protection in disputes between the clients themselves. Joint representation also triggers conflict-of-interest analysis because duties of loyalty and confidentiality run simultaneously to each client.

Family Auto Accident Conflict
Jasmine Jordan and her adult son Jerome Jackson were both injured when an uninsured driver struck their car. Their insurer retained one firm to pursue uninsured-motorist claims for both. After discovery showed Jerome may have been at fault, the firm faced disqualification because prior joint representation gave it confidential information from Jasmine that could now be used against her son.
Corporate Privilege Dispute
Jenkins Apparel and its former CEO June Jiang jointly consulted counsel about a securities filing. After the company sued Jiang for alleged self-dealing, the court ordered production of the joint-client communications because the privilege does not shield information when former joint clients litigate against each other.

Criminal Co-Defendant Appointment
Justin Jarvis and Judy Jacobs were charged together with mortgage fraud. The magistrate appointed one public defender to represent both at the initial appearance. The joint representation created an immediate risk that counsel could not zealously advocate for either defendant without compromising the other.

Frequently Asked
4
When does joint representation create a non-consentable conflict?+
A concurrent conflict arises when the lawyer's duties to one client will be directly adverse to another or will materially limit representation of either. In transactional settings the risk materializes when clients give opposing instructions on core terms such as debt levels or governance rights. Even informed written consent cannot cure the conflict if a disinterested lawyer would conclude competent representation of both is no longer possible.
Are communications between joint clients privileged against each other?+
No. When two or more clients consult the same lawyer on a matter of common interest, their communications lose attorney-client privilege protection if offered in a later dispute between those clients. The privilege continues to shield the communications from outsiders.
What must a federal court do when defendants appear with joint counsel?+
The court must promptly inquire into the propriety of the joint representation and personally advise each defendant of the right to separate counsel. Unless the court finds good cause to believe no conflict is likely, it must take measures to protect each defendant's right to effective assistance.
Does failure to object at trial waive a joint-representation conflict claim?+
A defendant who did not object must show that counsel actively represented conflicting interests and that the conflict adversely affected the representation. Reversal is automatic only when the trial court was advised of the conflict and failed to act.
