Division orders in Texas: what to check before you sign
Published September 23, 2026.
A division order usually arrives in an envelope with no covering letter, some months after a well has been completed, and it is the first document most new mineral owners are ever asked to sign. It is also the one they have the fewest ways to check. This guide is about what is on it, how the number was arrived at, and where Texas law draws the lines around it.
What a division order is
A division order is the payor’s statement of what it believes you own. It names you, names the property, states a decimal interest, and asks you to confirm it along with your address and your taxpayer number. The payor is the party that writes the checks, which may be the operator of the well or the purchaser of the production.
Two things about it are worth understanding before anything else.
It is not a lease and it is not a contract that changes your lease. Texas addresses division orders in section 91.402 of the Natural Resources Code, which sets out what a payor may require in one and provides that a division order which varies the terms of the oil and gas lease is not effective to that extent. The lease governs, and the current text of the section on the Texas Legislature’s website is the authority for the detail.
It is also revocable rather than permanent. A division order is the payor’s working record of ownership rather than a conveyance, so it transfers nothing, and it stays in force only until the owner revokes it.
The decimal
The whole document turns on one number, and the number is not arbitrary. Three fractions are multiplied together.
your tract's acreage in the unit / the unit's acreage 160 / 640 = 0.25
the royalty fraction written in your lease 1 / 5 = 0.20
the share of the minerals under that tract that you own 1 / 4 = 0.25
decimal interest 0.25 x 0.20 x 0.25 = 0.01250000
That worked example is a quarter interest in the minerals under a 160-acre tract, leased at a one-fifth royalty, pooled into a 640-acre unit. The result, 0.0125, means that 1.25 percent of the value of everything sold from anywhere in that unit is credited to you, before deductions and severance tax.
Three things commonly make a real decimal differ from your arithmetic, and none of them is sinister. The acreage credited to your tract may not be the acreage on the deed, because only the part of the tract inside the unit counts. Your share of the minerals may be smaller than you think if a prior owner reserved a non-participating royalty interest out of it. And where a tract has several owners, the payor is dividing one tract’s share among all of them.
Four things to compare
Four comparisons catch nearly every error that can be caught from the kitchen table.
Your name and address. Compare the spelling against the deed or the probate papers, not against your driver’s license. A name that reads as an estate, a trust or a deceased person means the payor’s title records have not caught up, and that is worth fixing before money starts moving.
The property description. The lease or unit name, the well number, the county and, where it is given, the survey and abstract should match the tract you believe is involved. A division order for a unit you have never heard of is either a newly formed unit that includes your tract or a mistake, and the difference matters.
The decimal, against your own arithmetic. Run the three fractions above with the numbers from your lease and the unit designation. If your figure and theirs differ in the third decimal place, something real is different; if they differ in the eighth, it is rounding.
The effective date. This is the date from which the decimal applies, and it should line up with first production or with whatever event changed your ownership. An effective date months later than first production is the usual sign that money is sitting in suspense waiting for you.
What you may change and what you may not
Correcting your own details is uncontroversial. A misspelled name, an old address, a taxpayer number entered wrongly: mark them, and most payors would rather have the correction than the signature.
A decimal you disagree with is different. The ordinary route is a letter to the payor’s owner relations department setting out your arithmetic and the documents behind it, rather than a signature with a number crossed out. Payors deal in volume and a struck-through form is often simply returned, while a letter with a unit designation and a deed attached gets read by somebody whose job it is.
Some division orders arrive with extra language attached: warranties of title, indemnities, or terms that look like lease provisions. Texas law is on your side here, in the sense that a division order cannot vary the lease, but what a particular clause does is a legal question and not one this guide can answer for your document. A Texas oil and gas attorney reading the lease and the division order together is the person who can, and for an interest of any size that hour is usually the cheapest part of the whole exercise.
Texas treats a signed division order as binding until it is revoked. Whether signing affects a claim for an earlier underpayment depends on who received the difference and on the facts, and that is a question for a Texas oil and gas attorney.
The W-9 and payment timing
A W-9 comes with almost every division order. It gives the payor your taxpayer identification number so it can report the income at year end; without one, the payor is obliged to withhold a portion of every payment until it has it. The W-9 is a tax form and has nothing to do with the lease.
On timing, section 91.402 of the Natural Resources Code sets the framework. The first payment is due within 120 days after the end of the month in which the production was first sold, and after that, at the frequency your lease or division order specifies; where neither says, the section sets outside deadlines of 60 days after the end of the month for oil and 90 days for gas. The same section lists the grounds on which a payor may lawfully hold proceeds, including a title dispute or a requirement it is entitled to impose, sets a minimum balance below which small amounts may be accumulated rather than paid, and provides for interest where a payment is late without one of those grounds. The figures and the wording have been amended over the years, so read the section itself rather than an article about it.
What to do next
Put the division order, the lease and the unit designation on the table together, and do the three-fraction multiplication once by hand. Keep a copy of the signed order with the lease, because it is the document that explains every check stub that follows.
Take a decimal you cannot reconcile, or any added language you do not understand, to a Texas oil and gas attorney before returning the form, and take the W-9 and the year-end reporting to a CPA.
