## Introduction

Conflicts of interest involving former and prospective clients can affect not only the individual lawyer but also their entire law firm. The Model Rules of Professional Conduct require lawyers to avoid representing clients in matters where their duties to former or prospective clients would create a conflict. In many cases, these conflicts are imputed to all lawyers in the same firm, but there are exceptions if proper screening and notice procedures are followed.

> **Key Term: Imputed Disqualification**
> The rule that prohibits all lawyers in a firm from representing a client when one lawyer is personally disqualified due to a conflict of interest, unless an exception applies.

### Former Client Conflicts and Imputation

A lawyer who has previously represented a client in a matter must not later represent another person in the same or a substantially related matter if that person’s interests are materially adverse to the former client, unless the former client gives informed consent, confirmed in writing.

> **Key Term: Substantial Relationship Test**
> A standard used to determine if two matters are so factually or legally connected that a lawyer’s representation of a new client would risk using confidential information from a former client to the former client’s disadvantage.

If a lawyer is disqualified from representing a client due to a former client conflict, the disqualification is generally imputed to all lawyers in the same firm. However, if the conflict arises from a lawyer’s association with a prior firm, the new firm may avoid imputation by timely screening the lawyer from any participation in the matter, ensuring the lawyer receives no part of the fee, and providing prompt written notice to the affected former client.

> **Key Term: Screening**
> The process of isolating a lawyer from any participation in a matter to prevent the sharing of confidential information and avoid imputed conflicts.

### Prospective Client Conflicts and Imputation

A lawyer who receives information from a prospective client that could be significantly harmful in a matter must not represent a client with materially adverse interests in the same or a substantially related matter. This conflict is also imputed to the lawyer’s firm unless:

- Both the affected client and the prospective client give informed consent, confirmed in writing; or
- The lawyer receiving the information took reasonable steps to avoid exposure to more disqualifying information than necessary, is timely screened, receives no part of the fee, and prompt written notice is given to the prospective client.

> **Key Term: Prospective Client**
> A person who consults with a lawyer about the possibility of forming a client-lawyer relationship, even if no representation results.

### Duty of Confidentiality to Former and Prospective Clients

Lawyers owe a continuing duty of confidentiality to both former and prospective clients. Information learned in the course of prior representation or consultation cannot be used to the disadvantage of the former or prospective client, except as permitted by the rules or if the information has become generally known.

> **Key Term: Confidential Information**
> Information relating to the representation or consultation that is not generally known and that the lawyer is obligated to protect from disclosure or misuse.

### Waiver of Imputed Conflicts

Imputed conflicts may be waived if each affected client gives informed consent, confirmed in writing, and the lawyer reasonably believes they can provide competent and diligent representation to each client.

### Screening Requirements

To be effective, screening must:

- Be implemented as soon as practical after the firm knows or should know of the need.
- Prevent the screened lawyer from accessing files, discussing the matter, or receiving any part of the fee.
- Provide written notice to the affected former or prospective client, describing the procedures and compliance.

### Worked Example 1.1

A lawyer at Firm X previously represented Company A in a patent dispute. The lawyer joins Firm Y, which is now asked to represent a competitor of Company A in a new patent case involving similar technology. Can Firm Y accept the new representation?

> **Answer:**
> Firm Y may represent the competitor only if the new matter is not substantially related to the prior dispute. If the matters are substantially related, Firm Y can proceed only if the lawyer is timely screened from any participation, receives no part of the fee, and Company A is promptly notified in writing. If these steps are not taken, the conflict is imputed and Firm Y is disqualified unless Company A gives informed consent, confirmed in writing.

### Worked Example 1.2

A prospective client meets with a lawyer at Firm Z and shares sensitive details about a potential lawsuit. The client does not retain the firm. Later, another lawyer at Firm Z is asked to represent the opposing party in the same matter. What must Firm Z do?

> **Answer:**
> Firm Z cannot represent the opposing party if the information received from the prospective client could be significantly harmful, unless the prospective client and the new client both give informed consent, confirmed in writing. Alternatively, if the lawyer who received the information is timely screened, receives no part of the fee, and prompt written notice is given to the prospective client, Firm Z may proceed.
>
> **Exam Warning:**
> Be careful: Imputed conflicts for former and prospective clients are not always automatic. Screening and notice can prevent disqualification, but only if all requirements are strictly met. Failure to implement screening promptly or to notify the affected client can result in the entire firm being disqualified.
>
> **Revision Tip:**
> Always check whether the conflict arises from a lawyer’s prior firm or from information obtained in a prospective client consultation. The rules for screening and notice are similar but not identical.
