N.Y. EPT. LAW § 7-1.9 : NY Code - Section 7-1.9: Revocation of trusts

(a)  Upon  the  written  consent, acknowledged or proved in the manner
  required by the laws of this state for the recording of a conveyance  of
  real  property, of all the persons beneficially interested in a trust of
  property, heretofore or hereafter created, the creater of such trust may
  revoke or amend the whole or  any  part  thereof  by  an  instrument  in
  writing  acknowledged or proved in like manner, and thereupon the estate
  of the trustees ceases with respect to any part of such trust  property,
  the  disposition  of  which has been revoked. If the conveyance or other
  instrument creating a trust of property was recorded in  the  office  of
  the  clerk  or  register  of  any  county  of this state, the instrument
  revoking or amending such trust, together  with  the  consents  thereto,
  shall  be  recorded  in  the  same  office  of every county in which the
  conveyance or other instrument creating such trust was recorded.
    (b) For the purposes of this section, a disposition,  contained  in  a
  trust  created  on or after September first, nineteen hundred fifty-one,
  in favor of a class of persons described only as the heirs, next of  kin
  or  distributees  (or  by any term of like import) of the creator of the
  trust does not create a beneficial interest in such persons.
    (c) A testamentary or lifetime trust wholly benefitting  one  or  more
  charitable   beneficiaries   may   be  terminated  as  provided  for  by
  subparagraph two of paragraph (c) of section 8-1.1 of this chapter.
