Submit an application to change the Land Register APIs

Use this service to help lodge applications with HMLR to update the register or create a new lease or transfer of part


Version and status


This developer pack is maintained by HMLR. If you’ve got a question, idea or suggestion, you can contact us or fill in our feedback form.

Overview

This new service will help to lodge applications with HMLR to update the register or create a new lease or transfer of part. It will be faster and more responsive than before and help identify errors prior to acceptance of an application. This will result in fewer requisitions and an improved experience for customers.

Using the new service API will mean that applications are only accepted onto the day list when the data provided is both valid and correct. Applications with validation errors will not be accepted. This will significantly reduce the number of avoidable administrative requisitions, identify common mistakes, such as name discrepancies or missing details, and increase our ability to automate applications.

You can read about the latest changes to these APIs in the release notes.
