2006 New York Code - Effect Of Disposition.

 
    §  1753.  Effect  of disposition.   A deed, mortgage, release or lease
  made in good faith, as prescribed in this article, upon  an  application
  in  behalf of an infant, incompetent person or conservatee, has the same
  validity and effect as if executed by the person in whose behalf it  was
  executed,  and  as  if  the  infant  were of full age or the incompetent
  person or conservatee were of sound mind and  competent  to  manage  his
  affairs.  It  shall  be  valid and effectual to vest in any purchaser an
  interest of an infant not in being at the time of the said sale, and any
  mortgage so  executed  shall  be  a  valid  lien  and  charge  upon  the
  contingent  interest  of  an  infant  not  in  being  at the time of the
  execution and delivery of the same. A release of an  inchoate  right  to
  dower as authorized by this article shall have the same effect as if the
  wife had joined with the husband in a deed or conveyance of the property
  affected  thereby  and  had  duly  acknowledged  the  same in the manner
  required by law to pass the estate of  married  women.  The  failure  to
  conduct  the  proceeding  strictly  in accordance with the provisions of
  this article shall not invalidate the disposition if  the  interests  of
  the infant, incompetent person or conservatee have not been prejudiced.
