A metal detecting permission form is a written agreement in which a private landowner authorizes a hobbyist to search for and recover buried objects on a described piece of property, for a defined period, under stated conditions. Without one, walking onto someone else’s land with a detector is trespassing, even if the owner gave a verbal “yes” the week before. The form protects the detectorist by proving authorization to any officer or neighbor who asks, and it protects the landowner by putting the terms of that authorization in writing.
Why Verbal Permission Isn’t Enough
A spoken “go ahead” is a revocable license. The landowner can withdraw it at any time, for any reason, and neither party has evidence of what was actually agreed. If the owner forgets the conversation, changes their mind, or sells the land, you have nothing to show. A written form fixes the who, where, when, and under what conditions before a coil touches the ground.
Writing also settles ownership of what you dig up. Depending on the state, found objects on private land may belong to the finder, the landowner, or both. Only about a dozen states recognize the traditional treasure trove doctrine, which generally awards buried valuables to the finder. Tennessee and Idaho award finds to the landowner. In most states the law is ambiguous enough that a written split prevents an ugly argument later.
Information to Gather Before You Draft
Before sitting down with the landowner, collect the details that turn a handshake into a usable document:
- Full legal names of both parties, as they appear on government-issued ID.
- Mailing addresses and phone numbers for both.
- The property’s street address plus the parcel number from the county tax assessor, which removes any ambiguity about which piece of land the form covers.
- A description of the permitted search area, with a printed map or satellite image attached and boundaries marked. Shade out anything off-limits: wells, septic systems, gardens, outbuildings.
- Specific start and end dates. Open-ended permission causes confusion. A defined window, say three months, gives a natural point to renegotiate.
The Clauses That Do the Real Work
The identifying fields tell you who and where. The clauses below tell you what each side is agreeing to. Skip any of them and you leave a gap.
Ownership of Discovered Items
This is the clause most likely to cause a fight if left vague. Three basic options: the detectorist keeps everything, the landowner keeps everything, or the two split finds by an agreed method. Common splits include a percentage of appraised value, first pick for the landowner on historically significant items, or the detectorist keeping modern coins and jewelry while the landowner retains anything potentially archaeological.
Write the arrangement in plain language. Sample club forms use broad phrasing like permission “to search for and recover buried coins, relics, and other artifacts,” which favors the detectorist. A landowner who wants to hold back certain categories needs to add limiting language. Specificity now prevents arguments later.
Liability Waiver and Assumption of Risk
All 50 states have recreational use statutes that reduce a landowner’s duty of care toward people using their property for recreation.1National Agricultural Law Center. States’ Recreational Use Statutes A waiver in the form adds a second layer. Standard language has the detectorist acknowledge the risks of being on the property, including uneven terrain, hidden holes, wildlife, and weather, and accept those risks voluntarily. It goes on to release the landowner from any liability claims for personal injury or property damage during the permitted period, and it should include an indemnification promise: if a third party sues the landowner because of something the detectorist did, the detectorist covers the costs.
Property Restoration
Require the detectorist to fill every hole and return the ground to its original condition. Typical language notes that “item recovery involves the digging of small holes, which will be repaired as nearly as possible to the land’s original condition.” You can go further by specifying that turf plugs must be cut cleanly and replaced flush, and that any trash pulled up leaves the property rather than getting reburied. Landowners who care about specific areas, such as manicured lawns or crop rows, should mark those off-limits on the attached map rather than relying on this clause alone.
Termination and Revocation
Because the form creates a license rather than a lease, the landowner can revoke it. One common phrasing: “This permission shall remain in effect until such time that I choose to revoke it by notifying the bearer in writing.” That gives the landowner unilateral control. At minimum the clause should say how notice of revocation is delivered (written notice, text, or email) and whether the detectorist gets a short window, perhaps 24 or 48 hours, to complete an in-progress session before access ends.
Signing and Carrying the Form
Both parties should sign and date on the same day, in each other’s presence. Signing together eliminates any later claim of forgery or misunderstanding. The date on the form should match the start of the permitted period or come before it.
Notarization isn’t legally required for a private land-access agreement in most situations, but a notary witness adds credibility if the document is ever challenged, and fees are modest. Notarized or not, make at least two physical copies and keep a digital scan. Carry your copy every time you detect on the property. If a neighbor calls the police or a family member of the owner doesn’t recognize you, a signed form ends the conversation.
Call 811 Before You Dig
The national 811 “Call Before You Dig” system connects you with local utility locators who will mark the approximate locations of underground gas, electric, water, and telecommunications lines at no charge.2U.S. Department of Transportation. Call 811 Before You Dig Most state laws require notification before excavation, and the definition is broad enough to cover shallow hand-digging. There is no universal exemption for digging only a few inches deep. Some utility lines run surprisingly close to the surface.
p>Call 811 a few business days before your first session. Add a line to the form putting responsibility for that call on the detectorist. Hitting a gas line is dangerous, and the repair costs and liability would fall on you.
If You Find Human Remains or Significant Artifacts
Most sessions turn up bottle caps and pull tabs. If you uncover what appears to be human skeletal remains, stop digging, leave everything in place, and contact local law enforcement. Many states have statutes requiring anyone who discovers unmarked human remains on private or public land to notify the county sheriff or medical examiner, often within 48 hours. State Historic Preservation Offices should also be notified when remains or associated cultural objects are found.3National Park Service. Compliance
On private land, state and local laws govern first. The Native American Graves Protection and Repatriation Act focuses primarily on federal and tribal lands, but items removed from private land may still fall under NAGPRA depending on who ends up controlling them. Selling or profiting from Native American human remains or cultural items obtained in violation of NAGPRA can carry criminal prosecution.3National Park Service. Compliance The form should include a clause requiring the detectorist to stop digging and notify the landowner immediately if any discovery appears to involve human remains, grave markers, or objects of potential archaeological significance.
What the Form Doesn’t Cover
A private-landowner permission form only authorizes activity on that private property. Metal detecting on federal land, including national parks, national forests, and Bureau of Land Management land, falls under the Archaeological Resources Protection Act. Unauthorized excavation or removal of archaeological resources from federal or Indian lands carries fines up to $20,000 and imprisonment up to two years for a first offense, and up to $100,000 and five years for repeat violations. Picking up arrowheads from the surface is the narrow exception.4GovInfo. 16 USC 470ee Some state and local public lands allow detecting with a permit, but rules vary. Check with the specific agency before bringing a detector onto anything you don’t have private written permission to search.
Taxes on What You Find
Under federal tax regulations, treasure trove is gross income in the year you take undisputed possession of it, valued in U.S. currency.5eCFR. 26 CFR 1.61-14 – Miscellaneous Items of Gross Income Dig up an $800 gold ring and you owe income tax on $800 that year, even if you never sell it. The taxable amount is the fair market value at the time of discovery.
If you later sell a found item for more than the value you originally reported, the profit is a capital gain. Collectibles like coins, art, and precious metals face a maximum capital gains rate of 28%, higher than the standard long-term rates on stocks or real estate.6Internal Revenue Service. Topic No. 409, Capital Gains and Losses Keep photographs of significant finds along with appraisals and sales records. If the form includes a split with the landowner, only your share is taxable to you.
Checklist for the Finished Form
You don’t need a lawyer to draft a workable form, though consulting one makes sense if valuable property or historically sensitive land is involved. The finished document should contain, in roughly this order:
- A title such as “Permission to Metal Detect on Private Property.”
- Full legal names, addresses, and phone numbers of both parties.
- Property street address, parcel number if available, and an attached map showing the permitted area and any restricted zones.
- A statement granting the bearer permission to use a metal detector to search for and recover buried items on the described property.
- Start date, end date, and any restrictions on days or hours.
- Ownership of finds, stated without ambiguity.
- A liability waiver in which the detectorist assumes all risks and releases the landowner from injury and damage claims, with indemnification.
- Property restoration terms: all holes filled, turf replaced, trash removed.
- Termination clause spelling out how the landowner can revoke permission and what notice is required.
- Utility acknowledgment putting responsibility for calling 811 on the detectorist.
- Discovery protocol for human remains or significant artifacts.
- Signatures and date, both parties present.
Print two copies, sign both, and each party keeps one. Carry your copy to every session. When the permission period expires, either walk away or negotiate a new form for the next round.
