HM Land Registry portal: unilateral notice (e-UN1)

How Business e-services customers can submit a unilateral notice on e-UN1 through the portal.

Enter the title number

Log in to the portal.

Select ‘Network Service’ then ‘e-UN1 Unilateral notice’.

  1. Some applications for a unilateral notice cannot be lodged as an eUN1. Select ‘View limitations’ to check details.
    If any of the limitations apply you will not be able to lodge the application as an eUN1. Instead you will need to apply using the Document Registration Service or by post or DX. Select ‘Previous’ to return to the process.

  2. Enter the title number.
  3. Select ‘Next’.

Check title details

  1. Check that the property details for the title number you entered are correct.
  2. If they are correct, select one of the options in ‘Application details’. These determine whether the application is against the whole of the registered estate, part of the registered estate, or a registered charge.
    If the application is against part of the registered estate, please provide a detailed description of the part of the land affected (for example, this could be a postal address or it could refer to an existing reference on the title plan).
  3. If they are not correct, select ‘Previous’ to go back and amend the title number if required.
  4. Select ‘Next’.

Availability of applications
