It is important for an attorney to withdraw from an action once the attorney has terminated the attorney-client relationship. If not, then the client may claim that the statute of limitations for legal malpractice has not been triggered, as decided in Courtney v McDonald, 176 AD3d 645 [1st Dept 2019]:
The first cause of action in plaintiffs’ complaint alleges legal malpractice with respect to defendants representation of plaintiffs in two underlying actions—the 304 W 18th Street matter and the 175 W 12th Street matter. Contrary to defendants’ argument, the malpractice cause of action with respect to the 175 W 12th Street matter is not time-barred by the three-year statute of limitations applicable to legal malpractice claims (CPLR 214 ). Defendants failed to demonstrate that the attorney-client relationship ceased to exist within three years of August 28, 2017, the date plaintiffs filed this action. Although defendants sent a letter, dated August 7, 2014, unilaterally terminating their representation of plaintiffs, they failed to move to withdraw from representation in the foreclosure action (see CPLR 321 [b]) until more than a year after sending the subject letter. Accordingly, to the extent plaintiffs’ first cause of action concerns alleged legal malpractice by defendants in their representation of plaintiffs in the matter concerning 175 W 12th Street, the motion to dismiss that cause of action was properly denied.
