Legacy litigation gives you the power to require oil and gas operators to restore contaminated soil and groundwater–and recover for lost land value. On September 1, 2027, Act 458 will replace Act 312, shifting cleanup decisions to the state agency, raising the burden of proof, capping damages, and assigning enforcement costs to landowners. To preserve your stronger rights under Act 312 Legacy claims, you must hire the right attorney now. These five Legacy litigation law firm questions will help you evaluate experience, resources, fees, communication, and strategy before you sign an engagement agreement.

What is Your Legacy Litigation Experience?

When evaluating a potential Legacy litigation law firm to partner with, you should ask about their experience with past Legacy claims. You want a firm who has handled many Legacy litigation suits–not a generalist trying to learn as they go.

Years in Practice and Case Volume

Look for a Louisiana Legacy litigation firm with experience in oilfield contamination claims. Ask how many Legacy litigation suits they have filed or resolved under Act 312. A respectable case volume shows they understand LDNR procedures, local judges, and parish-by-parish court rules.

Key Verdicts and Settlements

Past outcomes illustrate a firm’s ability to marshal complex scientific evidence and secure court-ordered remediation. Request examples of settlements or full-remediation orders against major operators. These examples help you judge whether the firm has the experience to translate technical proof into tangible cleanup plans and compensation.

Act 312 vs. Act 458 Expertise

Ensure the firm and their attorneys can explain how Act 312’s “preponderance of evidence” standard compares with Act 458’s “clear and convincing evidence” requirement. They should also describe how damages caps and risk-based cleanup under Act 458 could affect your claim–and why filing before September 1, 2027 matters.

Do You Have the Resources to Build My Case?

Legacy litigation requires complex expert studies and deep financial backing. Inquire about the attorney or firm’s fee structure, and confirm that you will not run out of funding or expert support mid-case.

Expert Network

Ask whether the firm has established relationships with geologists, hydrologists, and environmental engineers. These experts perform soil and groundwater testing, which is crucial to proving landowner rights in oil and gas contamination claims.

Financial Strength 

Legacy litigation often incurs expenses for scientific testing and expert reports. Confirm that the firm may advance expert fees and court costs on a contingency fee basis–so that you you are not asked to pay those expenses out of pocket if there is no recovery.

Team Structure and Support

Find out who manages filings, research, and client communications. You want a named lead attorney, a dedicated case manager for day-to-day questions, paralegals tracking deadlines, and trusted local counsel across key parishes.

How Will You Handle Fees and Costs?

New fee-shifting rules under Act 458 introduce financial risks. A transparent fee structure keeps surprises at bay.

Contingency-Fee Arrangement

Verify that you owe no attorneys’ fees or case costs unless the attorney wins or settles. Obtain the fee percentage in writing and confirm how expenses fees will be deducted from any settlement.

Fee-Shifting Risks under Act 458

Under Act 458, once a cleanup plan is approved, responsible parties pay no enforcement costs–and if the plan fails, you may even owe the defendant’s fees. An experienced Legacy litigation attorney will outline strategies to minimize this risk.

What Will Your Communication Look Like?

Legacy litigation cases can span years. You deserve reasonable updates on testing, filings, and settlement talks. Ask who your day-to-day contact will be, how quickly they return calls, and whether they are available for in-person meetings. Clear communication builds trust and keeps you in control every step of the way.

Point of Contact and Response Times

Determine who your direct point of contact will be. Confirm guaranteed callback or e-mail response times, such as within 24 hours. Reliable access builds confidence and trust.

What is Your Strategy for My Specific Case?

No two Legacy litigation claims are exactly the same. You need a customized plan. A strong attorney will outline how they screen sites, trace contamination to the right operators, and work with LDNR to draft the “most feasible” cleanup plan. They’ll also map out key milestones—notice filings, plan approvals, trial dates—and give you a realistic timeline. This shows they’ve thought through your unique facts and have a roadmap to pursue full remediation and fair compensation.

Initial Case Screening

Confirm whether they perform spot soil or groundwater tests and review historical lease records before filing notice. A solid initial screening filters out weak claims and focuses on the strongest cases.

Cleanup Plan Advocacy

Under Act 312, landowners choose the “most feasible plan” for full remediation. Ask how the attorney will work with LDNR to draft and defend your plan, pushing for complete cleanup rather than minimal, risk-based fixes.

Timeline and Key Milestones

Request a realistic roadmap: notice to LDNR, agency plan approval, trial or settlement. Understanding each phase and its duration helps you plan financially and manage expectations.
