Terms of Use & Novelty Disclosure
Last updated: 2 August 2026
1. This is a novelty gift item
Martian Estate sells decorative, collectible "Deed of Gift" certificates and printed plats of survey referencing notional parcels on the planet Mars, listed for sale individually on eBay. No purchase made through eBay or referenced by this Site conveys any real, legal, equitable, mineral, resource, orbital, or other property right in land on Mars or anywhere off Earth. Parcel boundaries, "estate valuations," acreage figures, and survey diagrams shown on this Site are illustrative and created for entertainment purposes; they do not correspond to any recognized cadastral or land registry.
2. Why no purchase can convey title
The Outer Space Treaty of 1967 (to which the United States, and most spacefaring nations, are party) provides in Article II that outer space, including the Moon and other celestial bodies, "is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means." No government on Earth currently recognizes private claims to Martian land, and no private registry — including this one — has any legal authority to grant such a claim. Any suggestion elsewhere that a "deed" of this kind is legally enforceable is incorrect.
3. What you receive
Each order is fulfilled at one item price, regardless of the parcel's displayed acreage or estate valuation. The Standard Gift Set includes one printed Deed of Gift certificate naming a recipient of your choosing and one printed plat of survey corresponding to the selected parcel number. Shipping is not included in the item price: actual USPS Ground Advantage postage is calculated based on the buyer's shipping address and charged separately at checkout. Parcels are listed for sale one at a time on eBay; current pricing, shipping costs, and any promotions for a given parcel are shown on its eBay listing and are subject to change.
4. Displayed "estate valuations"
The per-parcel prices shown on parcel and browse pages on this Site are presented in the style of a real estate listing for atmosphere and are not the amount charged at checkout. The amount charged is the gift-set item price plus shipping, as shown at checkout.
5. Checkout partner
Purchases are completed on eBay, operated by eBay Inc. ("eBay"), a separate online marketplace. eBay's own terms of sale, privacy notice, buyer protection policies, and payment terms govern the transaction itself, including how your payment and shipping information are handled. We are not responsible for eBay's platform availability, but Martian Estate remains responsible, as the seller, for order fulfillment, listing descriptions, and this novelty disclosure. At any given time, only some parcels may have an active eBay listing; parcels without one are not currently for sale.
6. No resale market, no investment
Parcels, certificates, and plats sold here have no inherent monetary value beyond their value as a keepsake or collectible, are not securities or investment products, and should not be purchased with any expectation of financial return or appreciation.
7. Intellectual property
Plat designs, parcel numbering, and site content are the property of Martian Estate. Regional names used (e.g., Olympus Mons, Valles Marineris, Tharsis, Amazonis Planitia, Elysium) refer to real, publicly documented Mars surface features and are used descriptively.
8. Limitation of liability
The Site and its content are provided "as is." To the fullest extent permitted by law, Martian Estate disclaims liability for indirect, incidental, or consequential damages arising from use of the Site or reliance on any statement about a parcel's value.
9. Changes
We may update these terms from time to time; the date above reflects the latest revision.
