Under CPLR 3211(a)(1), dismissal based on documentary evidence is warranted only if the evidence utterly refutes plaintiff's factual allegations, conclusively establishing a defense as a matter of law. The burden is on the defendant to demonstrate that the evidence is documentary. In order to be considered documentary, the evidence must be unambiguous and of undisputed authenticity, such that it is unassailable. Judicial records, as well as documents reflecting out-of-court transactions such as mortgages, deeds, and unambiguous contracts may qualify as documentary evidence.
