Trust-Owned Minerals

A trustee holding mineral rights is managing an asset that behaves nothing like the stocks and cash sitting in the rest of the trust portfolio.

Trusts often end up holding minerals the same way estates do, through a grantor who transferred family mineral interests in decades ago and a trustee who now has to manage something with no ticker symbol, no quarterly statement in a familiar format, and no easy comparable to check the value against. We’ve worked with individual trustees managing a parent's estate plan and with corporate trust officers at banks, and both groups tend to ask the same first question: what is this thing actually worth.

The trustee's fiduciary duty to the beneficiaries doesn't change because the asset is unusual, but the process for prudently managing or selling a mineral interest looks different from rebalancing a bond portfolio, and it's worth understanding before making a decision either way.

The trustee's duty with an unusual asset

A trustee generally has a duty to manage trust assets prudently, which for a mineral interest can mean actively monitoring lease terms, royalty payments, and operator changes rather than letting the asset sit unattended. For a producing interest, that's an ongoing obligation, checking statements, confirming decimal interests are correct, and staying aware of well performance, that some trustees are equipped for and others are not.

For a corporate trustee managing dozens of accounts, a small mineral interest that requires this kind of specialized attention often isn't worth the administrative overhead relative to its size in the overall trust. That mismatch between the effort required and the interest's proportional value is one of the most common reasons trustees decide to sell rather than continue managing it directly.

Documenting the decision for beneficiaries

Because trustees owe a duty to beneficiaries, a sale of trust property, especially something as illiquid and hard to comparably value as minerals, generally needs to be documented well: how the value was determined, whether multiple offers were sought, and why selling serves the trust's interests better than holding. A written offer that lays out the basis for the number, recent royalty history for a producing interest, or comparable leasing activity for non-producing acreage, gives the trustee something concrete to put in the file.

Some trust instruments specifically address how mineral interests should be handled, including whether the trustee needs beneficiary consent or court approval for a sale. Reading that language carefully, or having the trust's attorney confirm it, is worth doing before soliciting offers, since it can affect the process even if it doesn't affect the eventual price.

Producing interests inside a trust

If the trust's mineral interest is producing, the trustee typically has real income data to work with, both for ongoing distribution decisions to income beneficiaries and for valuing the interest if a sale is on the table. That said, decline curves matter here just as much as anywhere else, an interest paying well today may be paying significantly less in three years, which is worth factoring into whether the trust holds for continued income or converts to a lump sum that can be invested more predictably elsewhere.

Trusts with both income and remainder beneficiaries sometimes face tension here, income beneficiaries may prefer holding for the royalty stream while remainder beneficiaries may prefer a sale that preserves principal value before it declines. That's a conversation for the trustee and the trust's attorney, but having a real market number for the interest makes that conversation far more concrete.

Non-producing minerals and diversification

Non-producing mineral acreage held in a trust is a concentrated, illiquid, single-asset bet on future drilling in one specific county, which runs against the diversification principle most trustees are otherwise expected to follow with the rest of the portfolio. That alone leads plenty of trustees to sell non-producing interests even when there's no urgent need for cash, simply because holding a speculative, undiversified asset is harder to justify under a prudent-investor standard than holding a diversified basket of securities.

We work with trustees regularly and provide the documentation, a written offer with the basis for the valuation, that supports the kind of record-keeping a trustee's duty requires, whether the trust ultimately sells or decides to hold.
