merging leashold and freehold

A few years ago I bought the freehold of my house.  I now have two registry entries for my house linked to me, the freehold and the leasehold.  I would like to merge them to one freehold.  what forms do I need to submit if I take them to the local land registry office, in person with my passport.

Ian - Merger can occur where a leasehold estate in land, together with the reversionary estate, come into the ownership of the same person and are held in the same capacity. <p>There must also be a clear intention to merge the estates.</p> <p>Any mortgage on the leasehold title must be discharged.</p> <p>The lease is absorbed by the reversionary estate and thus determined. For details of the various situations that may be encountered, the treatment of beneficial easements affecting the leasehold estate and how to make your applications against any affected titles, please see&nbsp;<a href="https://www.gov.uk/government/publications/leases-determination/practice-guide-26-leases-determination#determination-on-merger">Determination: on merger</a>.</p> <p>You also need to take appropriate action in respect of the&nbsp;<a href="https://www.gov.uk/government/publications/leases-determination/practice-guide-26-leases-determination#points-to-consider">Points to consider on all applications</a>, which sets out:</p> <ul> <li>what forms you should complete in respect of each affected title</li> <li>the documents you need to send</li> <li>how to act if either the lease being determined or its reversionary title are unregistered</li> <li>fees payable&nbsp;</li> <li>how to deal with any incumbrances affecting the determined lease</li> </ul> One of the key reasons why merger is not always requested is because the lease includes rights that would be lost if it was 'determined' (closed)<br> Land registration is complex, designed to protect legal and financial interests in property.
