196501-274986 FOI Section 106

I am writing to request information under the Freedom of Information Act, regarding developer contributions, or Section 106 payments. 
 
Specifically, my request concerns unpaid and overdue payments, for example payments that were tied to a specific date or point in a project, or payments that have been invoiced for but not received.
 
For every payment that is owed to the council, I would like the following details:
a) The amount of money owed;
b) The date by which it was supposed to have been paid OR;
c) If payment is tied to a trigger point in development rather than a date, then the date an invoice was raised
d) The reference number for the associated planning case
