Yes. Lea county clerk You might get lucky and find leases and royalty deeds.
Depending on the age of the documents, it is easy or time consuming.
Old stuff is found by searching indexes and finding book and page number and them requesting that page from the county clerk. There are two indexes one for grantor and one for grantee.

If you click on “Scanned Index” on the Clerk’s Office Lookup you will get the old stuff that is not online.
I have found the Lea county staff friendly and pleasant to work with. They do require book and page number though. That’s what you find in the index.
