Usually not yet, and every law firm's website stops right there. Here is the part nobody finishes: what it actually takes, what it actually costs, how long it actually runs, and how we handle it so the sale and the paperwork happen at the same time instead of one after the other.
You can sign a contract to sell. You generally cannot deliver good title until the chain of ownership from the deceased owner to you has been fixed in the public record. Almost every serious buyer requires marketable title, and a bare affidavit of heirship usually does not create it.
That is not a reason to give up. It is a sequencing problem, and sequencing problems are solvable. What it is not is a reason to accept a lowball from whoever tells you the title is worthless.
An affidavit of heirship is a sworn statement, usually by someone who knew the family, reciting who the heirs are. It is cheap and fast, and it is genuinely useful. Operators frequently accept one to start paying royalties, which is why so many families have one on file and assume the problem is solved.
Paying royalties and conveying title are different questions. An operator accepting an affidavit is deciding who to mail a check to, and it can change its mind later. A buyer taking a deed is committing real money on the strength of the record forever. An affidavit is evidence of heirship; it is not an adjudication of it. Anyone with a competing claim can still surface.
In practice: affidavits often work for small, old, non-producing interests where the risk is proportionate. They rarely work when there is real money involved, a will, a surviving spouse with an elective share, minors, a prior marriage, or an estate that owed debts.
Less than most people fear. If the only asset is a mineral interest and the heirs agree, Oklahoma's summary administration is available for smaller estates and moves considerably faster than a full probate. Typical published attorney fees for a straightforward mineral-only probate start in the low thousands, and a summary proceeding commonly runs on the order of a couple of months rather than a year.
If the decedent lived outside Oklahoma and was probated in their home state, you generally need an ancillary probate in Oklahoma to move Oklahoma real property, which minerals are. That is usually a shorter and cheaper proceeding because the hard work was already done elsewhere.
There are also non-probate paths worth asking about. A transfer on death deed recorded before death, a properly funded trust, or joint tenancy with right of survivorship can avoid probate entirely. Our article on transfer on death deeds covers when each applies.
Not out of pocket, in most cases we handle.
Here is how we usually structure it. We value the interest and make an offer. If you accept, we sign a purchase agreement that is contingent on title being cured, and we pay for and coordinate the curative work, including the probate or the ancillary probate, as part of the transaction. You sign what needs signing. At closing you receive the agreed price, and the cost of clearing title has come out of our side, not yours.
That is not charity, it is arithmetic. We are going to own the interest, so we need clean title anyway, and we do this work constantly at a cost and speed an individual family cannot match. It also means you are not writing a check to a lawyer for an outcome you are not certain of.
Two honest caveats. First, this only works when the interest is worth enough to justify the curative cost, and we will tell you plainly if it is not. Second, if the family is in genuine conflict about who the heirs are, no buyer can paper over that. It has to be resolved.
Very common, and easier to solve than families expect. A check stub, an old lease, a division order, a tax return with royalty income on Schedule E, or just a county name gives us a starting point. We run the courthouse records and the state regulator's files and tell you what we find. That research is free and you are under no obligation, and we do it whether or not you ever sell.
If nothing has been paid in years, the money may be sitting in operator suspense or state unclaimed property. Our unclaimed royalties guide walks through recovering it, and in Oklahoma there is no deadline to claim.
Sometimes no, and we will say so. If the interest sits in an area with active permitting, holding may beat selling by a wide margin, and we would rather tell you that than buy something cheap from someone who did not know. Our when not to sell page is a buyer's honest list of the situations where keeping is right.
Where selling usually does make sense: the interest is small and fractional, the heirs are scattered across states, nobody wants to manage it, or the estate needs cash to close. Splitting one check is simpler than splitting an undividable asset among five people forever.
Send a check stub, a name, or a county. We will find the interest, tell you what title work it needs, what that costs, what the interest is worth, and whether we would pay for the curative as part of a purchase. Free, and no obligation of any kind.
