Not a novelty deed. A timestamped, surveyed, publicly-contestable good-faith claim — the strongest documented case a person can make today for recognition if and when off-world property rights are ever formalized.
We do not sell legal title — no one on Earth can. We build the most defensible documented claim file in existence, and we tell you exactly what it is.
For forty-five years the "buy land on Mars" business has mailed people a $25 certificate with no survey, no public record, and no process behind it. We built the opposite.
Brazilian acquisitive-possession law, U.S. homesteading, and mining-claim law all share one principle: documented, peaceful, continuous, good-faith possession of land you actually work can ripen into recognized title. We run that exact process — off-world.
Pick a parcel in the explorer. We georeference it on the body's official coordinate frame and issue a memorial descritivo.
GeorreferenciamentoWe run a claim-search certificate, take a notarized possession attestation, and verify your identity.
Ata Notarial de PosseYour claim is publicly advertised for 24 months. Anyone in the world may file a counter-claim during the window.
Edital de CitaçãoCounter-claims are resolved by date and evidence. Unopposed claims earn a Certificate of Unopposed Possession.
Posse mansa e pacíficaYou sign a 25-year commitment to develop the parcel when transit exists, and re-attest annually to keep possession continuous.

Our founding parcels sit where humanity is actually most likely to settle: confirmed water ice, near-continuous solar power, and the flattest, safest ground. That makes the "work the land" commitment credible — and the resource memo real.
The lunar south pole — confirmed water ice in permanently-shadowed craters, with "peaks of eternal light" for near-continuous power. NASA's Artemis destination, mapped to the metre by LRO.
Shallow subsurface water ice, flat and landing-safe, mid-latitude — a long-favoured candidate for the first human landings on Mars. Superb HiRISE and MOLA coverage.
Every claim is built from real legal instruments, each mapped to its homesteading or usucapião analog. This is what $2,500 buys that $25 cannot.
A founding claim secures your place in line as one of the first documented, publicly-recorded homestead claimants on a body — and starts the 24-month process.
A founding claim is a documentation and registry service and a collectible — your good-faith, first-mover claim file. It is not a legal title, not an investment, and recognition by any future authority is not guaranteed. You are buying the strongest documented claim a person can make today — and our honesty about what it is.
Your homestead commitment is your own good-faith pledge to develop the parcel when transit exists. We never promise that transit will come, never resell your claim for profit, and never represent a financial return.
No conveyance of legal title. The 1967 Outer Space Treaty (Art. II) bars national appropriation of celestial bodies, and no sovereign, court, or land registry currently has jurisdiction to grant or enforce private title to land on the Moon, Mars, or any celestial body. Spaceclaims does not and cannot convey legal ownership or any presently-enforceable property right.
What you purchase. A claim-documentation and registry service — the preparation, notarization support, public publication, opposition-period adjudication, and continuous-possession recordkeeping of a good-faith homestead claim — together with a collectible certificate. It is a record of your claim and intent, not a title.
Not an investment; not a security. Your payment is not an investment of money in a common enterprise and carries no expectation of profit from our efforts. We make no representation as to resale value, appreciation, or return. The claim is not offered as a security and is not registered with the SEC, any state regulator, the Brazilian CVM, or any other authority.
No guarantee of recognition; no sovereignty. We model the process on frameworks in which documented good-faith possession was sometimes later recognized, but we do not guarantee any government, court, or treaty body will ever recognize your claim. No Spaceclaims claim asserts national sovereignty over any celestial body. Nothing here is legal, tax, or financial advice.
