Launching 2026 — Founding rate locked for first 500

A records system and Do Not Solicit registry for Texas mineral owners.

Context

Mineral ownership generates a paper trail. We help you keep it.

Most mineral interests change hands through inheritance. The owner ends up with leases, division orders, royalty stubs, deeds, and probate documents — sometimes spanning decades, often across multiple counties or states. Mineral buyers pull owner names from public courthouse records and contact owners directly. Mineral.Locker addresses both: a place to keep the records, and a registry that tells buyers not to contact you.

Mineral records are scattered across years and parties
Lease from one operator, royalty stubs from another, deeds at the county clerk
Mineral buyers find owners through courthouse records
Public deed indexes are the entry point. Skip-trace fills in the rest.
There is no government Do Not Solicit list for mineral buyers
We operate a private registry under Texas Business & Commerce Code § 17.46
Owners often need to act on their records — review a lease, audit a royalty, prepare for inheritance
When the time comes, having organized records reduces friction
Phone with missed calls and unopened mail on a kitchen counter
Records and registry, together.
One place for what you own. One registry for who shouldn't be contacting you.
When a buyer won't stop

Three steps. Each one builds the evidence file.

Most buyers stop at the registry notice. If they don't, we have a documented path forward.

Step 1 — Monthly

Registry Notice

A consolidated USPS Certified letter goes out monthly to every known buyer, listing all registered owners on the Do Not Solicit roster. Return receipts logged.

Step 2 — On request

Documented Demand Letter

Per-buyer demand letter drafted from your evidence file, citing federal and state statutes (TCPA, TX DTPA § 17.46, others as applicable). You sign as yourself. We mail USPS Certified.

Step 3 — On demand

Counsel-Ready Evidence Package

Every certified mailing, return receipt, buyer reply, and reported event — assembled, timestamped, and exported as a PDF + structured file. Hand it to any Texas-licensed attorney you choose, if you choose.

Who builds this

Built by people who work in courthouses.

Mineral.Locker is built by landmen who spend their working hours running title in Texas county clerk offices. We know the records, the operators, and the buyers active in each basin. That experience is reflected in how the registry mailings are addressed and what the demand letter templates cite.

Mineral.Locker is software and mail infrastructure. We are not a law firm and do not provide legal advice. The customer signs every demand letter as themselves, and any escalation to litigation is the customer's decision with counsel of their choice.

FAQ

Common questions

Two things: a document vault where you can upload and organize your mineral records (leases, division orders, royalty stubs, deeds, heirship documents, operator correspondence, harassment letters), and a listing on the Do Not Solicit registry. Each month we mail a consolidated certified letter to known mineral buyers that includes every registered owner's name. There is no charge for either of these.
Each month, one consolidated USPS Certified letter is mailed to every known mineral buyer in Texas. The letter contains the current Do Not Solicit roster (the names of all registered owners) and a reference to Texas Business & Commerce Code § 17.46. USPS return receipts are logged. Buyers can acknowledge compliance through a unique reply address printed on the letter, which adds them to the public buyer compliance directory.
Active services. Weekly monitoring of public records for new leases, deeds, lawsuits, probate filings, and other activity affecting your interests. A demand-letter generator that drafts per-buyer letters from your evidence file, citing federal and state statutes. Identity protection that removes your phone and address from people-search sites that buyers use to find owners. The free tier holds your records; the paid tier acts on them.
On the paid plan, you can request a per-buyer demand letter. We draft it from your evidence file with citations to the relevant statutes for your state, the state where your minerals are, and the state where the buyer operates. You sign as yourself. We mail USPS Certified. If a buyer continues contact after that documented notice, every interaction is timestamped and added to a Counsel-Ready Evidence Package you can hand to a Texas-licensed attorney of your choice.
No. Mineral.Locker is software and mail infrastructure operated by Our Landmen LLC. We do not provide legal advice. We provide document automation, evidence storage, and certified mail. The customer signs every demand letter as themselves. If you decide to engage an attorney to file a claim, we can refer you to vetted Texas-licensed counsel; you would hire and pay them directly.
That's your decision. If you opt in to receiving offers, your information is handled through a separate sister DBA (Heir Land), under explicit consent. Mineral.Locker itself does not sell owner information to buyers. The trust firewall between owner-side and buyer-side products is intentional and non-negotiable.
Home Title Lock monitors residential title and notifies you of changes. Mineral.Locker is built for mineral records (which differ from residential title in scope and frequency), and the free tier includes record storage in addition to notifications. The paid tier also includes outbound suppression mail to known buyers and demand-letter generation — neither of which Home Title Lock offers.
Texas first. Expansion to Oklahoma, Louisiana, New Mexico, and North Dakota requires a per-state legal review of the demand-letter templates and is on the roadmap. Register on the free tier and indicate your state on the form; we will notify you when coverage extends.
