Re: Definition of "Grantor" in Subsequent Sales
the grantor is the original person to grant an easement to the grantee.
what is sounds like is one person owned both lots at one time, or they may have even been 1 lot split into 2 lots. That person was actually both the grantor and the grantee. The words " reserve for myself etc." would indicate he owned that lot and when he sold it, he created the easement so he would be able to access the lot he retained.
then you had better step up and offer to purchase this other lot. There is nothing you can do to extinguish the easement.
I would be willing to buy the land-locked property but this issue will affect the value of both properties.
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
