CPLR 3211 (a)(1) is the "documentary evidence" portion of a general pre-answer motion to dismiss.  The standard applied to dismissal motions under this particular sub-section is:

"On a motion to dismiss based upon documentary evidence, dismissal is only warranted if the documentary evidence submitted conclusively establishes a defense to the asserted claims as a matter of law" (Klein v Gutman, 12 AD3d 417, 418; see CPLR 3211[a][1]; Saxony Ice Co., Div. of Springfield Ice Co., Inc. v Ultimate Energy Rest. Corp., 27 AD3d 445). Moreover, where "evidentiary material is submitted and considered on a motion to dismiss a complaint pursuant to CPLR 3211(a)(7), the court must determine whether the plaintiff has a cause of action, not whether the plaintiff has stated one" (Steve Elliot, LLC v Teplitsky, 59 AD3d 523, 524, citing Guggenheimer v Ginzburg, 43 NY2d 268, 275). "[U]nless it has been shown that a material fact as claimed by the [plaintiff] to be one is not a fact at all and unless it can be said that no significant dispute exists regarding it . . . dismissal should not eventuate" (Guggenheimer v Ginzburg, 43 NY2d at 275).
 

Here, in the quote taken from Walker v Kramer ; 2009 NY Slip Op 04414 ;  Decided on June 2, 2009 ;  Appellate Division, Second Department we see a situation in which neither defendant demonstrated their right to dismissal.  Plaintiff has adequately stated a cause of action, or indeed, has a cause of action which the court discerned, in this matrimonial legal malpractice case.
