Pre-death Deed Transfer

My Mom has 24 Oil and Gas rights within Jackson County WVa.. I have talked to the County Assessor to collect Tax Records, I have a copy of the deed last completed in 1995 by my mother. Her wishes are to transfer to me (son) to avoid dealing with Probate cross state lines (Mom is in Texas and I am in Colorado).
I have the Sales Listing Form that Jackson County Clerk advise me to submit along with the property listing details. Reading in this forum there seems to be something missing legally. Do I need to have a lawyer actually draw up a new Deed or some letter that is signed by my Mom and notarized to go along with the Sales Listing Form? Do I need an O&G Lawyer or can any lawyer provide this service?
Looking for any clarifying guidance from the group
