Questions about Shared Mineral Rights

In case of shared mineral rights, if one signs a lease and the others do not, would the person who signed get paid for the lease? Can the lessee drill even if not all have signed? Also, can the ones who haven’t signed sign a lease with a competing company? Who has the rights to drill in this case?

That answer is dependent on what state your minerals are located. Can you please include the State and County?

The mineral rights are in Nueces County, Texas.
