Hello. Welcome to The Mineral Rights Forum! We are all new to this at one time but don’t worry there are many knowledgeable people here from about everywhere. First off, what state are the minerals located in? Every state has a different online system and Texas seems to use a different style of legal description. Also, what is the legal description of the property? An example for Oklahoma would NE1/4 Section 15 T5N 3W. Will be needed for the professionals on this forum to give a good answer. That will get a start on this.
Good Luck, Josh
