Section 47-D. Cancellation of assignment

Upon the payment or satisfaction
  of the indebtedness, and upon written demand delivered personally or  by
  registered  mail  by  the  assignor,  the  assignee  shall  execute  and
  acknowledge or prove, and deliver to the assignor a certificate  setting
  forth  that  the  indebtedness  has been paid or otherwise satisfied and
  discharged. Such certificate must recite the date of the assignment, the
  names of the parties thereto, the amount of the  original  indebtedness,
  the   filing  number,  the  date  of  filing  thereof,  including  every
  assignment of said assignment, if any, specifying in the recital of each
  assignment the date thereof, the  names  of  the  parties  thereto,  the
  filing date and the serial number thereof.
    If  for  ten  days  after  such  demand  the assignee fails to mail or
  deliver such a statement  of  satisfaction,  he  shall  forfeit  to  the
  assignor  five  dollars,  and  be  liable for all damages suffered. Upon
  presentation of such statement of satisfaction the filing officer  shall
  file  the  same and note the cancellation of the assignment and the date
  thereof on the margin of the page where the assignment has been entered.
