§   5-1552.  Form  of  designation.  1.  Designations  in  general.  A

  of the designee, the name of each minor  or  incapacitated  person  with
  respect  to  whom  such designation is made, the parent's signature, and
  the date of such signature. The designation may specify a period of time
  less than twelve months for which such designation shall be valid unless
  earlier revoked by such parent pursuant to section 5-1554 of this title,
  provided that any designation specifying a period of  more  than  thirty
  days  shall  also  conform  to the provisions of subdivision two of this
  section.
2. Designations for more than thirty days. A designation specifying  a
  period  of  more  than  thirty  days  shall also include: an address and
  telephone number where  the  parent  can  be  reached,  an  address  and
  telephone number where the designee can be reached, the date of birth of
  each minor or incapacitated person with respect to whom such designation
  is  made,  the  date  or  contingent  event  on  which  the  designation
  commences, the written consent of the designee to such designation,  and
  a  statement  that  there  is  no  prior  order  of  any  court  in  any
  jurisdiction currently in effect prohibiting such parent from making the
  designation. A designation specifying a period of more than thirty  days
  shall be notarized.
3.  Designations  not  specifying  a time period. If no time period is
  specified in a designation, it shall  be  valid  until  the  earlier  of
  revocation  or  the expiration of thirty days from the date of signature
  if the designation does not meet the requirements of subdivision two  of
  this  section,  or twelve months from the date of commencement specified
  therein if the designation meets the requirements of subdivision two  of
