How many years do i need to look to see who owns the mineral rights under my property?

To determine who owns the mineral rights under your property, you may need to look back at the property deed and any associated documents, which typically extend back to the original land grant or transfer. This could involve researching property records for 20 years or more, depending on local laws and the history of the land. Consulting with a title company or a real estate attorney can provide more specific guidance and streamline the process.
