   Petition for writ of certiorari to the Seventeenth Judicial Circuit,
Broward County; John B. Bowman, Judge; L.T. Case No. CACE-17-
021733 (02).

  Kelly Anne Luther, Danielle Fannie Moriber and Giselle Gonzalez
Manseur of Kasowitz Benson Torres LLP, Miami, for petitioner.

  William R. Scherer, Russell R. O’Brien and Eric M. Yesner of Conrad &
Scherer LLP, Fort Lauderdale, for respondent, Steven Mariano.

PER CURIAM.

    Kasowitz Benson Torres LLP seeks certiorari review of an order denying
its motion to stay or abate a legal malpractice action until the underlying
litigation is resolved. We grant the petition and quash the order because
the outcome of the underlying litigation will determine whether the plaintiff
incurred any damages as a result of Kasowitz’s alleged malpractice.

   The plaintiff, Steven Mariano, and his company, Patriot National, sold
shares of stock to certain hedge fund investors in late 2015. Simpson
Thacher & Bartlett LLP represented Mariano and Patriot National in
connection with the transaction. The investors later sued both Mariano
and Patriot National in federal court in New York. Kasowitz briefly
represented Patriot National in the New York litigation, which is still
ongoing.

   In 2017, Mariano sued both Simpson and Kasowitz for legal
malpractice. As to Simpson, he claims the firm negligently drafted
documents related to the hedge fund transaction and failed to adequately
warn him of the risks of the transaction. As to Kasowitz, he claims the
firm negligently drafted affirmative defenses in the New York litigation and
failed to advise him of viable claims against Simpson for malpractice. Both
firms moved to stay or abate the action, arguing that Mariano’s claims
were premature because the underlying litigation was still ongoing. The
trial court denied the motions, and Kasowitz timely filed this petition.

    A claim of legal malpractice generally does not accrue until the
underlying litigation is resolved with an adverse outcome to the client. See
Perez-Abreu, Zamora & De La Fe, P.A. v. Taracido, 790 So. 2d 1051, 1054
(Fla. 2001) (citing Blumberg v. USAA Cas. Ins. Co., 790 So. 2d 1061, 1065
(Fla. 2001)); Silvestrone v. Edell, 721 So. 2d 1173, 1175 (Fla. 1998). If the
client files a complaint while the underlying litigation is pending, the case
should be abated upon a showing that the outcome of the underlying
litigation will determine whether the client incurred any damages as a
proximate cause of the alleged malpractice. See Perez-Abreu, 790 So. 2d
at 1054; Burgess v. Lippman, 929 So. 2d 1097, 1098 (Fla. 4th DCA 2006).

    Here, Mariano’s claims against Kasowitz should have been abated
because the outcome of the underlying litigation will determine whether
Mariano incurred any damages as a proximate result of Kasowitz’s alleged
instances of malpractice. More specifically, the outcome of the New York
litigation will determine whether Mariano incurred damages as a result of
Kasowitz’s alleged malpractice in drafting the affirmative defenses, and the
outcome of the malpractice claims against Simpson will determine whether
he incurred damages as a result of Kasowitz’s alleged malpractice in failing
to advise him that he had viable claims.

   Accordingly, we grant the petition for writ of certiorari and quash the
order denying the motion to stay or abate as to Kasowitz.
