In the legal profession, being ethical is more than just good practice. It's mandatory. One of the most basic steps in being ethical is performing a conflict check. A proper conflict check protects current and former clients, prevents malpractice claims, and ensures attorneys meet their fiduciary duty.
In this post, we’ll go over what a conflict check is, how the conflict check process works, and why every law firm needs a conflict checking system.
What Is the Conflict Check Process?
A conflict check is a systematic review done by a law firm to identify potential conflicts of interest before an attorney-client relationship is established. This review ensures that representing a new or potential client won’t interfere with duties owed to existing clients, former clients, or other parties involved in ongoing or past matters. The goal is to protect confidential information, avoid conflicts, and maintain ethical boundaries.
The conflict check process starts before the initial consultation. This is part of the broader client intake process and should be done before any legal services are offered. At this stage, attorneys and staff gather all relevant information about the potential client, the opposing party, related parties, and any co-defendants. This data is cross-checked against the law firm’s existing database.

Why Law Firms Must Address Conflicts
The need to address conflicts comes from the legal profession’s emphasis on loyalty and confidentiality. Attorneys owe a fiduciary duty to their clients, and a failure to identify potential ethical violations can lead to serious consequences, including bar complaints, malpractice claims, or disqualification from representing a client.
In today’s legal landscape, many law firms serve multiple clients with overlapping or adverse interests. Without a conflict checking process, the risk of breaching client trust increases significantly. Identifying potential conflicts early in the client onboarding process is key to long-term ethical compliance.
Key Trigger Points for a Conflict Check
There are several key trigger points when a conflict check should be done:
- When a new client approaches the firm
- When taking on a new matter for an existing client
- When hiring a new attorney from a former firm
- When merging with another law firm
- When an attorney switches sides in litigation (e.g., a former prosecutor now in private practice)
Each of these scenarios can trigger interest rules or expose confidential information. Performing a conflict check at these stages helps prevent issues from escalating.
Types of Conflicts: Who Could Be Affected?
Conflicts can arise with current and former clients, opposing counsel, related parties, or even within the firm itself due to personal interest. For example, representing a potential client whose interests are directly adverse to an existing client or a previously represented party can pose a significant risk.
Other parties, such as co-defendants or individuals affiliated with corporate clients, must also be reviewed during the conflict check process.
In some cases, a conflict can be waived if informed consent is obtained from all affected clients. However, even with conflict waivers, firms must be careful. Not all conflicts can be ethically waived, and the waiver process must be documented thoroughly.
Manual Process vs. Conflict Checking Software
Traditionally, law firms used a manual process for conflict checks. This involved checking spreadsheets, physical files, or internal memory, which increases the risk of human error. While feasible for small firms with limited caseloads, this becomes time-consuming and risky as the firm grows.
Modern firms use conflict checking software or integrated legal practice management software to streamline the process. These systems allow firms to maintain a conflict check database, flag potential ethical violations, and document the steps taken to resolve any issues.
How Conflict Checking Software Speeds Up the Process
Conflict checking software speeds up the review process by quickly cross-referencing a potential client's information against the firm’s database of case records, parties involved, and other relevant data. This reduces reliance on memory or paper records and provides consistent, trackable outcomes.
Some of the best conflict checking systems integrate directly with legal practice management software. This integration allows staff to run a conflict check automatically during the client intake process, helping identify potential conflicts during onboarding. The software also supports tracking informed consent, conflict waivers, and documenting any communication related to conflicts.
Building a Reliable Conflict Check System
A reliable conflict check system is more than just software. It includes clearly defined policies, staff training, and ongoing database updates. Every member of the law firm involved in intake or case assignment should understand their role in compliance.
To build a strong system, consider:
- Maintaining an up-to-date conflict check database
- Training all staff on identifying potential conflicts
- Reviewing conflict waivers for each matter
- Ensuring documentation is stored properly
- Integrating practice management software with conflict checking tools
Virtual legal assistants can also support this process by organizing client information, entering data into the system, and flagging entries for attorney review. This is especially helpful in firms with high-volume client onboarding.
Common Problems and Ethical Dilemmas
Despite best efforts, conflict checks are not foolproof. Ethical violations can arise from incomplete data, lack of communication, or outdated records. A conflict may not be apparent unless the firm collects detailed information about the potential client, including their relationships, affiliations, and past legal matters.
Another issue arises when an attorney previously represented a client at a former firm. In those cases, it's important to consider not just the matter itself but whether confidential information was obtained and how it may impact the new representation.
In some cases, declining representation is the safest option. If there is a significant risk of breaching professional conduct rules, the firm must prioritize ethics over business development.
Keeping Ethical Standards in a Busy Law Firm
As firms grow and take on multiple clients across jurisdictions and practice areas, the likelihood of encountering potential conflicts increases. Firm leaders must prioritize conflict checks as part of their daily workflow. The attorney-client relationship begins with trust, and that trust is fragile when interests are misaligned.
Implementing the best conflict checking system is not just about avoiding bar complaints or legal consequences. It is about protecting client relationships and being a firm of integrity.
Final Thoughts
Conflict checks are a critical component of any law firm’s risk management and ethics strategy. They are essential for identifying potential conflicts, preserving confidential information, and ensuring that the attorney-client relationship is built on trust.
From the initial consultation to the full scope of legal services, the entire process of onboarding a client must be backed by a reliable conflict check system. Whether using advanced conflict check software or a more manual process supported by trained staff, the goal remains the same: to avoid conflicts, address potential issues early, and uphold the standards of the legal profession.
A law firm that invests in maintaining accurate, consistent, and timely conflict checks not only protects its clients but also strengthens its own reputation as a trustworthy legal counsel.
