Start with the recorded deed and its legal description, then trace earlier conveyances for mineral reservations or separate grants. When an interest was severed, follow that mineral chain forward as well as the surface chain. County records support the investigation; a parcel-specific title examination establishes what the seller can convey.

Start with the interest you intend to buy
If your plan is to buy acreage, sell the surface and keep the minerals, the first useful question is whether the seller owns the interest you want to retain. A listing that says “all rights convey” does not answer it. The phrase still needs an ownership history behind it. Write the proposed asset in one sentence: all of the seller’s oil and gas interest beneath a specified tract, for example, or a stated fraction of a broader mineral estate. That sentence is a research brief, not deed language. It tells the title examiner what must be established before the economics can be trusted. Keep a separate file for each tract. Save the tax parcel identifier, county, municipality, apparent surface owner, deed recording reference and legal description. If the offering combines several tax parcels, do not assume that their mineral histories match. One tract might have a reservation that another never had. The buy-land, retain-minerals strategy depends on this distinction. You cannot create a retained asset by reserving an interest the seller never conveyed to you.

Get the complete recorded deed
The county recording office is the starting place for conveyances. New York Real Property Law § 291 addresses recording in the county where the property is situated and the priority consequences of unrecorded conveyances. Recording matters, but a recorded document still has to be interpreted and connected to the right property. Ask for the entire instrument, including exhibits and the recording cover sheet. The cover sheet helps identify the filing. The operative language and attached description explain what the document purports to transfer. A database index entry or a single screenshot is an incomplete substitute. The Cortland County Clerk’s real-property guide illustrates the range of relevant records: deeds, mortgages, easements, leases and other instruments. It also distinguishes an abstract, prepared by a private company, from documents held by the clerk. Ask the seller whether an existing abstract is available, then have its scope and currency checked. Search the grantor and grantee names shown in the deed. Record spelling variants, company names and earlier ownership names rather than relying only on a street address. Confirm with the local office how its indexes cover older material and where records outside the online collection can be examined.

Read backward for the first separation
Follow the references to earlier deeds and flag language reserving, excepting or separately conveying oil, gas or minerals. Also flag references to another document without assuming that the present deed reproduces everything that matters. The referenced instrument belongs in the file. Make a chronological table. For each document, record the execution and recording dates separately, parties, recording reference, described land and the rights language that needs review. Keep the exact text in your working notes. A summary such as “minerals excluded” can hide a crucial limitation to one substance, depth, fraction or part of the tract. Do not impose a convenient stopping point because the online search goes back only a certain number of years. Ask the examiner what search period and additional records are necessary for this particular interest. A quick surface search and an examination directed at an old mineral reservation are different assignments. Silence in the latest deed is not a research result. Your question is whether earlier instruments affected the interest now being offered and whether later events changed that position. If an old clause is ambiguous, mark it unresolved instead of translating it into a definite ownership claim.

Then follow the mineral chain forward
Finding the original reservation identifies a point of separation. It does not, by itself, identify today’s mineral owner. The next task is to follow transfers of that reserved interest forward, independently of subsequent surface sales. Consider a hypothetical chain. An owner sells the surface in 1940 while retaining a specified mineral interest. The surface changes hands three more times. Meanwhile, the reserved interest passes through an estate and is later divided between successors. Searching only the current surface owner’s name would miss the separate sequence that determines who can sell the minerals. Ask counsel which estate, trust, corporate or court records are needed to establish each transition. A familiar surname is not proof that an individual succeeded to the whole interest. A deed signed by one apparent owner does not establish that other interests have disappeared. Build a working ownership schedule with columns for claimed owner, fraction, substances, tract, supporting document and unresolved link. Keep “claimed” in the heading until the examination supports a firmer conclusion. If fractions do not reconcile, identify the discrepancy; do not fill the gap with an assumption that the surface owner owns the balance.

Prove that the documents cover this land
An ownership chain can be coherent and still describe a different tract. Old lot references, exceptions from larger holdings and later parcel splits require a location analysis alongside the document search. In Champlain Gas & Oil, LLC v People (2017) , the appellate court reversed summary judgment against a surface owner because the mineral claimants had not adequately established the location and boundaries of their claimed estate. The decision makes a practical point for a buyer: possession of an old mineral deed does not finish the geographic work. Use county GIS to orient the investigation and obtain parcel references, then reconcile them with the legal descriptions and appropriate survey evidence. Broome County’s GIS portal expressly warns that its parcel information is not a substitute for surveys or legal documents. When an offering consists of a carved-out piece of a larger historic tract, ask the examiner to identify the relevant exceptions and overlap. A highlighted polygon is helpful for discussion. It cannot resolve a gap between the old description and the acreage being sold.

Separate ownership from leases and payment rights
A recorded oil and gas lease introduces another question: what rights has the owner already granted to someone else? It is not interchangeable with a mineral deed. The DEC leasing guide describes a lease as granting exploration and development rights under a contract. Collect assignments, amendments and releases as well as the original lease. Ask who holds the lease now, what land and formations it covers, whether it remains effective and which payments belong to the interest being purchased. The mere age of the document is not an adequate answer. A seller’s past royalty statement may be a useful lead, but it does not replace the instruments establishing entitlement. Likewise, the presence of a nearby well does not tell you who owns the minerals beneath the parcel. Keep operating records and title records in separate folders, with links where they actually connect. Our mineral deed versus lease guide explains why the distinction changes both the purchase price and the exit you can reasonably plan.

Commission an answer you can use in the purchase
Give the title professional a clear assignment: determine what mineral interest this seller can convey in this described tract and identify the evidence, exceptions and unresolved issues. If you intend to retain rights on a surface resale, include that proposed structure in the brief. Ask the title insurer what the proposed policy would cover and exclude. Ownership research, a legal opinion and insurance coverage are different deliverables. A policy for one transaction should not be assumed to insure every mineral issue important to your strategy. Request a short written conclusion tied to the supporting instruments. It should let you distinguish confirmed scope from unresolved scope without rereading the entire file every time the asking price changes. Keep copies available for the next buyer’s review; the ability to explain the asset is part of preparing a sale. Before making an offer that assigns value to mineral rights, put the seller’s proposed conveyance beside that conclusion. If the two do not match, change the contract, price or research plan before you commit money to the missing interest.

COMMON QUESTIONS
Does a New York tax map identify the mineral owner?
A tax map helps locate the parcel and surface record. It does not replace the separate deed and title research needed to establish mineral ownership.

Is there one document that proves the seller owns all minerals?
A deed is part of the evidence. Earlier reservations, later conveyances and the connection between their descriptions and the present parcel must also be examined.

Can I start the search myself?
You can collect deeds, recording references and related instruments. Use that organized file to commission the parcel-specific examination needed for a purchase or reservation.
