If you own oil and gas mineral interests in Oklahoma, chances are you may have received an offer to lease. While this can be exciting, remember that an oil and gas lease is a contract and the terms of this contract can have a big impact on your rights. This includes your future royalty payments. The oil and gas lease you sign today can control how your royalties will be paid for decades to come, and small clauses in your lease can mean big differences in the amount of royalty payments you eventually receive. Ask your attorney to review any oil and gas lease before you sign.
