The issue that arises often in litigation is: when was the plaintiff put on notice that the lawyer may have breached the duty of care? The answer to this question often determines whether or not the statute of limitations bars a claim. A case decided by the Delaware Supreme Court earlier this year captioned, ISN Software v. Richards, Layton & Finger 226 A.3d 727 (Del. Supreme Court), offers a thoughtful discussion of that very issue.
ISN Software wished to convert to an S Corporation. However, four of its shareholders could not legally be shareholders of an S Corporation. Thus, the question was how can we remove these shareholders from our company? The law firm allegedly advised ISN to use a merger to cash out the four shareholders. The way it typically works is that the company offers the shareholder a cash payment. If the shareholder accepts the cash offer, that is the end of the matter. If the shareholder elects appraisal, there is a court case where a judge decides the value of the shares. In this transaction, all four shareholders were eligible for appraisal rights. The law firm told the client in 2013 that its legal advice on who was eligible for appraisal was incorrect.
The company proceeded to litigate the value of the shares. When the court made its decision, the value was substantially higher than ISN thought it would be. ISN then sued the law firm for malpractice. The Delaware courts held the the case was time-barred because the cause of action accrued in 2013 (when the firm told the client that the advice it had given was incorrect) not 2018 when the unfavorable litigation ruling occurred.
