Acquisition & Divestiture Due Diligence

Know what you’re buying.
Know what you’re selling.
Close with confidence. 

For E&P A&D teams, land departments, PE-backed operators, and mineral and royalty buyers. 

Protecting deal value on both sides of the transaction 

In an oil and gas transaction, purchase price is only as solid as the title behind it. A missed title defect, an unrecorded lien, or an unflagged preferential purchase right can erase value overnight after closing. 

Feighny Hartle gives buyers and sellers a crystal-clear assessment of the assets on the table. We move at deal speed and price our work proportionately so diligence never becomes the reason a deal fails to pencil. Because our attorneys examine land records every day, we know precisely where title risks hide—and which ones actually matter to your bottom line. 

Buy-side due diligence 

We verify exactly what you are paying for before funds transfer: 

• Ownership & Yield Verification: Comprehensive review of Working Interest (WI) and Net Revenue Interest (NRI). 

• Lease & Contract Review: Analysis of lease terms, expirations, depth severances, continuous development, retained acreage clauses, JOAs, farmouts, and gathering/marketing agreements. 

• Encumbrance & Transfer Restrictions: Searches for liens, lawsuits, bankruptcies, preferential rights, and consents to assign. 

• Defect Strategy: Precise title defect notices and defect valuation support to protect your purchase price adjustments. 

Sell-side preparation 

The best time to discover a title defect is before your buyer does. We examine your asset base ahead of marketing to help you defend your ask: 

• Pre-sale title and ownership auditing 

• Data room organization and ownership record staging 

• Proactive curative work prior to buyer diligence 

• Defense strategies and formal responses to buyer defect notices 

Closing & Post-Closing Support 

• Purchase and Sale Agreement (PSA) diligence review and title representations 

• Drafting conveyances, assignments, and closing documentation 

• Post-closing curative execution and division order updates
