An application for amendment or discharge of agreement s106 may be submitted to the local planning authority at the end of the `relevant period`, and the `relevant period` is defined as a period of five years from the date on which agreement s106 is concluded. In the case of an agreement under section 52 or an agreement under section 106 of the old style (i.e. an agreement concluded before 25 October 1991), the only way is to apply to the Lands Tribunal for discharge or amendment of a restrictive agreement under section 84 of the Prosperity Act 1925. This procedure does not specifically focus on planning agreements. The Landsgericht may adopt or amend a restrictive covenant where the restriction is obsolete due to changes in the nature of the property or the vicinity or other circumstances of the land; if its existence prevents a reasonable user of the land; or if the modification or discharge does not prejudice the rightholders. If you want to modify an s106 agreement, you must first think about the duration of its presence. If agreement s106 was concluded less than five years ago, an agreement must be sought between the parties. . . .
