Definitive Map Modification Orders

​Any person believing details contained within the Definitive Map or Statement to be incorrect may apply for a Definitive Map Modification Order (DMMO) which, if made and confirmed, will amend the map and statement to ensure that it is a correct record of the public rights of way. 

When can you apply for a DMMO?

The grounds to apply for a DMMO are that:

  • a right of way exists but is not shown on the Definitive Map and Statement
  • a right of way shown on the Definitive Map and Statement with a particular status ought to be shown with a different status
  • a right of way shown on the Definitive Map and Statement does not exist and ought to be removed
  • any other particulars contained on the Definitive Map and Statement need modification (e.g. the width of a right of way)

Investigations into a claimed route are concerned with whether or not public rights exist. Issues of nuisance and desirability are not relevant to an application for a DMMO.
