Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
What is the issue with the driveway?
Can you prove the fence was moved after the death of your father?
Actually the wording of the Will is clear - you and your brother inherit the land you each occupied at the time of the your father's death.
In the absence of any agreement between you then that is the default position and is how the land should be registered - rather than it temporarily being placed in the names of the Executors (which is indeed legal)
I suggest that you inform the Executors that it is in fact within their powers to end the matter in this way and any failure to do so may lead to your making a claim against them
Please ask if you need further details
Does the Registration actually require his signature - is it creating or transferring covenants
One option is for the Executors to deal with the assent of your property to you and then for the other property to be transferred to the Executors until your brother is able to agree to sign
You are very welcome and I hope all goes well
