It is ironic when attorney errors harm an otherwise good legal malpractice case.  Leeder v Antonucci  2019 NY Slip Op 05898 [174 AD3d 1469] July 31, 2019 Appellate Division, Fourth Department is an example.

“We reject plaintiff’s contention that Supreme Court erred in granting the cross motion with respect to the biofuel cause of action. It is well settled that “a necessary element of a cause of action for legal malpractice is that the attorney’s negligence caused ‘a loss that resulted in actual and ascertainable damages’ ” (New Kayak Pool Corp. v Kavinoky Cook LLP, 125 AD3d 1346, 1348 [4th Dept 2015]), and that “ '[c]onclusory allegations of damages or injuries predicated on speculation cannot suffice for a malpractice action’ ” (id.). With respect to the biofuel cause of action, defendant met his initial burden on the cross motion by establishing that plaintiff’s allegations of damages are entirely speculative (see Lincoln Trust v Spaziano, 118 AD3d 1399, 1401 [4th Dept 2014]; Bua v Purcell & Ingrao, P.C., 99 AD3d 843, 848 [2d Dept 2012], lv denied 20 NY3d 857 [2013]), and thus plaintiff is “unable to prove at least one of the essential elements of [his] legal malpractice cause of action” (Boglia v Greenberg, 63 AD3d 973, 974 [2d Dept 2009]; see Grace v Law, 108 AD3d 1173, 1174-1175 [4th Dept 2013], affd 24 NY3d 203 [2014]). Plaintiff failed to raise an issue of fact in opposition (see generally Zuckerman v City of New York, 49 NY2d 557, 562 [1980]). We are unable to review plaintiff’s contention that he raised a triable issue of fact with respect to those damages by submitting an expert report inasmuch as plaintiff failed to include that document in the record on appeal. Thus plaintiff, as the party raising this issue on his appeal, “submitted this appeal on an incomplete record and must suffer the consequences” (Matter of Santoshia L., 202 AD2d 1027, 1028 [4th Dept 1994]; see Resetarits Constr. Corp. v City of Niagara Falls, 133 AD3d 1229, 1229 [4th Dept 2015]).”
