Section 3-3.8. Validity of a purchase of real property notwithstanding its

disposition by will
    The title of a purchaser of real  property,  in  good  faith  and  for
  valuable  consideration,  from a distributee of a person who died owning
  such property shall not be affected by  a  testamentary  disposition  of
  such  property  by  the  decedent,  unless  within  two  years after the
  testator's death the will disposing  of  the  property  is  admitted  to
  probate.   If, however, at the time of the testator's death, the devisee
  is either an infant, incompetent, imprisoned for a term less than  life,
  without  the  state  or  if the will was concealed by one or more of the
  distributees of the decedent, the two year period prescribed herein does
  not commence until the expiration of one  year  from  the  time  of  the
  removal of such disability or the delivery of the will to the devisee or
  to the surrogate having jurisdiction to admit the will to probate.
