Garage lease variation - ID requirements

There is a minor wording error in a clause of my  garage lease (I have a freehold house but a garage under a coach house). The freeholder of the coach house is paying because they want to sell. The freeholders solicitor will draw up the document. I don't need a solicitor as the error is clear.

Does this need registering at the land registry?
If so what ID do I need to provide to the freeholders solicitor so that the Land Registry can accept the amendment?

 

Bally 53 - it reads as if they are drawing up a deed of variation and if so that will need to be registered against both the freehold and leasehold titles.
If your property is mortgaged then your lender's consent is likely to be required and they may insist that you do use a solicitor
We don't routinely require identity verification for such an application but the solicitor will obviously need to be sure that they are dealing with the right leaseholder so will have their own needs.

Thank you for your reply regarding the ID requirements.

The DoV is just a one word correction in the lease that clarifies a clause.  

Is lender consent required if it doesn't affect their security on my property? Would the solicitor decide this or is it Land Registry who checks?

Assuming that the corrrect extent and term have been demised by the garage lease but other provisions require amendment, I would refer you to section 4.5 of practice guide 68: amending deeds that effect dispositions of registered landbut other provisions require amendment.
