Prospective Liability Limit Rejected
Penelope Price retained Pierce Patterson to handle a personal injury suit. Patterson asked her to sign an agreement capping his liability for any future errors at the amount of his fee. Price had no separate lawyer review the document before signing. When Patterson later missed a key deadline and the claim was lost, the agreement provided no protection against her malpractice suit.
Concealment Turns Negligence into Misconduct
Paige Porter missed the statute of limitations on Preston Pratt's contract claim. She paid Pratt from her own funds to hide the error and never told him he might have a malpractice claim or suggested he consult independent counsel. The disciplinary board found the concealment and conflict of interest warranted sanctions beyond ordinary negligence.

Isolated Error Does Not Trigger Discipline
Prime Logistics hired Perry Pratt to file a cargo-damage suit. Pratt miscalculated the limitations period and the claim was barred. The client sued for malpractice and recovered damages. The bar declined to impose discipline because the single miscalculation did not demonstrate unfitness to practice.
Self-Defense Exception Allows Disclosure
Pinnacle Holdings sued its former law firm for overbilling and inadequate representation in a merger. The firm obtained and used the client's discovery responses and internal instructions to defend the malpractice claim. The court permitted the disclosure under the self-defense exception because the client had placed the representation at issue.
Duty Arises from Initial Consultation
Pierre Poulin met with Prism Analytics' counsel for an initial consultation about a potential trade-secret claim. The lawyer evaluated the facts, gave advice on next steps, and never followed up. The statute of limitations expired without warning. Poulin sued for malpractice and the court held that the consultation created an attorney-client relationship and duty of care.
Auditor Liability to Third Parties Limited
Pacific Bank relied on an audit report prepared by an accounting firm for a borrower. The report contained errors that the bank claimed caused it to extend a bad loan. The court held that the auditors owed no duty of care to the bank as a nonclient absent a direct relationship or known intended reliance.
