# Legal Conflict-of-Interest Check

A conflict-of-interest check verifies that a lawyer or firm can
ethically represent a prospective client, given the firm's current and
former client relationships, before accepting representation — a
required professional-responsibility step, not an optional courtesy.

## Common types of conflicts

- **Direct adversity** — the firm currently represents a party directly
  opposed to the prospective client in the same or a related matter.
- **Former client conflicts** — the firm previously represented a party
  whose interests conflict with the prospective client's, particularly
  where confidential information from the former engagement could be
  relevant.
- **Positional conflicts** — advocating a legal position for one client
  that directly undermines another client's interest in a different,
  unrelated matter.
- **Personal or business conflicts** — a lawyer's own financial or
  personal interest that could compromise independent professional
  judgment.

## Why this check happens before engagement

Conflict checks happen before accepting a new matter specifically
because accepting a conflicted engagement can require withdrawing
later (at real cost and disruption to the client), and — more
seriously — can expose confidential information or produce a breach of
duty that's difficult or impossible to remedy after the fact.

## Common pitfalls

- **Relying on memory rather than a systematic conflict database** — a
  firm of any real size needs a maintained, searchable record of past
  and current clients and matters; informal recall is unreliable and
  risky.
- **Checking only the named parties, not related entities** — a
  conflict can arise through a parent company, subsidiary, or closely
  related party not immediately obvious from the named parties alone.
- **Treating a conflict check as a one-time gate** — new conflicts can
  arise mid-representation as new matters come in; ongoing monitoring
  matters, not just a check at intake.
- **Proceeding on an ambiguous conflict without proper waiver** — some
  conflicts can be waived by informed client consent, but that consent
  needs to be genuinely informed and properly documented, not assumed.
