Professional help selling mineral rights usually means more than one person. NARO tells owners to consider an attorney when evaluating a sale, dealing with probate or correcting title defects, and a CPA when selling or reporting royalty income and depletion (NARO, Owner FAQ, Oct 2026). For a formal value it names a petroleum engineer for the production forecast and a valuation professional to turn that forecast into fair market value (NARO, Oct 2026).
This page sets out what each professional does in a sale, then lists the official public lookups for lawyers, engineers and CPAs in ten producing states, with what each lookup confirms. A lookup confirms a license and its status; it does not confirm experience with minerals or competence. AMR names no individual professionals and ranks none.

Which professional does which part of a mineral sale?
An attorney reads the deed and contract and handles probate and title, a landman researches ownership, an engineer forecasts production, a valuation professional prices it, and a CPA handles the tax. NARO points owners to several of them together for a sale.
When do you need an attorney or a CPA?
NARO lists when each is worth calling.
- NARO tells owners to consider an attorney when evaluating a sale, dealing with probate or inheritance, correcting title defects, or signing documents they do not fully understand (NARO, Owner FAQ, Oct 2026).
- NARO tells owners to consider a CPA or tax adviser when selling mineral interests, planning an estate, or reporting royalty income and depletion (NARO, Owner FAQ, Oct 2026).
- For a sale, NARO points owners to appraisal, legal, tax, financial and sale services together, since value, timing and terms interact (NARO, Professional Help, Oct 2026).
- For high stakes decisions NARO names petroleum engineers, geologists, certified mineral appraisers, registered professional landmen and experienced oil and gas attorneys (NARO, Oct 2026).
What does a landman do?
Records research and ownership work, usually for the industry side.
- NARO describes a landman or title professional as useful for researching ownership, reviewing county records and preparing a mineral inventory (NARO, Owner FAQ, Oct 2026).
- AAPL defines a landman as the public facing member of an exploration and production team who negotiates with landowners to acquire leases (AAPL, Oct 2026).
- AAPL says independent field landmen research courthouse records, determine ownership, locate owners and obtain curative documents (AAPL, Oct 2026).
- AAPL says independent land consultants also perform the due diligence examinations required when companies and properties are bought and sold (AAPL, Oct 2026).
What do an engineer and an appraiser each add?
The engineer supplies volumes and timing; the appraiser supplies prices, risk and the value.
- NARO names a petroleum engineer, an engineering consulting firm, or a certified mineral appraiser or valuation professional for an engineering based evaluation (NARO, Oct 2026).
- In a formal valuation the petroleum engineer supplies the production forecast and the valuation professional turns it into fair market value (NARO, Oct 2026).
- NARO lists what the valuation professional adds: price assumptions, royalty and deduction mechanics, a risk based discount rate and market evidence (NARO, Oct 2026).
- NARO warns that a purchase offer is not an independent appraisal and advises getting multiple opinions before selling (NARO, Owner FAQ, Oct 2026).
Report types and the firms that prepare them are compared in mineral rights appraisal.
Where do you check each license, state by state?
On the licensing body's own lookup in the state where the minerals are. The table lists the official lookup for lawyers, engineers and CPAs in ten producing states; NASBA's national CPAverify covers nine of the ten accountancy boards.
What do the lawyer lookups show?
Status, in most states, and sometimes discipline.
- The Oklahoma Bar Association's Member Verification shows each lawyer's bar number, membership type, status such as good standing, and admission date (Oklahoma Bar Association, Oct 2026).
- North Dakota's court list shows each lawyer's bar number and status and can be filtered by status (North Dakota Courts, Sep 2026).
- Colorado's Attorney Search shows a lawyer's status and disciplinary history (Colorado Office of Attorney Regulation Counsel, Oct 2026).
- Pennsylvania's Look Up an Attorney tool searches by name, number, city, county or status (Disciplinary Board of the Supreme Court of Pennsylvania, Oct 2026).
- West Virginia's directory filters by member type, including active, inactive, suspended and annulled (West Virginia State Bar, Oct 2026).
What do the engineer and CPA lookups show?
A license and its status, each with the board's own caveats.
- The Texas engineering roster lists engineers with a renewable license and labels each status, of which only active is valid for practice (Texas Board of Professional Engineers and Land Surveyors, Jun 2025).
- Pennsylvania verifies engineers and CPAs in the PALS database, which shows license number, status and any board discipline (Pennsylvania Department of State, Oct 2026).
- Ohio's eLicense lookup covers both the engineering and the accountancy boards, among 24 state bodies (eLicense Ohio, Oct 2026).
- NASBA says CPAverify is fed by participating boards at intervals from daily to quarterly, so a state board's own lookup is more current (NASBA, Oct 2026).
- CPAverify lists the Colorado, Louisiana, North Dakota, Ohio, Oklahoma, Pennsylvania, Texas, West Virginia and Wyoming boards as participating, and New Mexico's as not yet (NASBA, Oct 2026).
What does a lawyer search tell you about mineral experience?
Usually nothing. A listing shows a license; Texas alone lets you filter for board certification in oil, gas and mineral law, and some directories are not status checks at all.
Which directories are not status checks?
Some public directories are lists, not verifications.
- The Supreme Court of Ohio states that inclusion in its attorney directory does not necessarily mean good standing (Supreme Court of Ohio, Oct 2026).
- Oklahoma's separate Find a Lawyer directory is voluntary, omits some licensed lawyers, and the bar does not endorse or certify anyone listed (Oklahoma Bar Association, Oct 2026).
- New Mexico's online bar directory searches by name, practice area and county; a license status field was not shown on the pages read (State Bar of New Mexico, Oct 2026).
Where can you see a mineral law credential?
In Texas, through the bar's own search.
- The State Bar of Texas directory can filter by board certification, and Oil, Gas and Mineral Law is one of the listed areas (State Bar of Texas, Sep 2026).
- The Texas directory gives basic information on lawyers licensed in Texas, with no warranty of accuracy (State Bar of Texas, Sep 2026).
What does a landman certification mean?
It is a credential from the American Association of Professional Landmen, not a state license, and its status cannot be checked in a public search.
What are the three certifications?
RL, RPL and CPL, open only to AAPL members.
- AAPL offers three landman certifications, RL, RPL and CPL, and only AAPL Active Members may apply (AAPL, Oct 2026).
- Of the three, only the CPL requires a four year college degree (AAPL, Certification FAQs, Oct 2026).
- RPL and CPL certifications renew every five years and the RL every year (AAPL, Certification FAQs, Oct 2026).
- Every AAPL member commits to AAPL's Code of Ethics and Standards of Practice, an association commitment rather than a state license (AAPL, Oct 2026).
Can you check a landman's certification?
Not publicly, on the pages read.
- AAPL's online member search finds members by name, company and region, but shows contact details only to logged in members (AAPL, Find a Member, Oct 2026).
- No public lookup of certification status was found; the member search filters cover name, company, job title, location and work area (AAPL, Find a Member, Oct 2026).
- Under AAPL's bylaws, landwork includes reviewing title status and title due diligence in mineral acquisitions and divestitures (AAPL, Certification FAQs, Oct 2026).
What do these lookups not tell you?
Whether someone knows minerals or works for buyers, and for some CPAs and landmen, whether any public record exists.
What limits do the lookups themselves state?
Each board states its own limits.
- New Mexico licenses engineers as professional engineers, not by discipline, so its roster shows the exam discipline rather than a petroleum license (New Mexico engineering board, Oct 2026).
- West Virginia says out of state CPAs from substantially equivalent states may perform accounting services there, so a CPA missing from its lookup may still practice (West Virginia Board of Accountancy, Oct 2026).
- West Virginia's engineering board gives licensure status for engineers and firms with no guarantee of accuracy (West Virginia engineering board, Jun 2026).
- NARO's directory of professionals is a members only list of supporting organizations, not a public credential lookup (NARO, Professional Help, Oct 2026).
Which lookups could not be read?
Three. Each is listed so you know to check it another way.
- The Louisiana State Bar's directory sits behind a word verification check, so its status display could not be read (Louisiana State Bar Association, Oct 2026).
- Colorado's engineering board links its license check to the state's DORA lookup, which sits behind a human verification check and was not read (Colorado engineering board, Dec 2024).
- Wyoming's engineering board links a license search that returned an access error when read (Wyoming engineering board, Oct 2026).
Questions to put to a CPA before a sale are listed in tax questions before selling inherited mineral rights.
Methodology and Sources
Roles come from NARO's owner FAQ, valuation guide and professional help page, and from the American Association of Professional Landmen's own pages. Every license lookup was opened on the licensing body's site on October 8, 2026, or, where the site did not load from AMR's network, in an Internet Archive capture of the same page, dated in the citation. Each lookup is described only by what it confirms, a license and its status; none confirms competence or mineral experience, and AMR names and ranks no individual professionals. The table is rechecked when a board changes its lookup.
