A frontier claim dossier on a dark desk — a surveyed plat map, an embossed certificate with a red wax seal, a fountain pen, brass dividers and a vial of rust-red soil
The product is the paperwork

A 19-instrument possession file — notarized, published, maintained.

Where competitors mail a single printed "deed," we assemble a multi-instrument, notarized, publicly-published, continuously-maintained dossier modeled on Brazilian usucapião, U.S. homesteading, and mining-claim law. The rigor is what $2,500 buys that $25 cannot — and, paired with our honesty about not conveying title, it's the legal safety too.

Every claim includes all nineteen

The complete file

Each instrument maps to a real legal analog so the file reads like a genuine possession dossier — not a souvenir.

Why each one matters

The survey establishes what you claim

The memorial descritivo and georeferencing fix your parcel on the body's official coordinate frame with latitude-corrected boundaries — the same rigor Brazil requires for rural land registration. A parcel anyone can re-locate is a parcel anyone can recognize.

The attestations establish that you possess in good faith

The ata notarial de posse, the good-faith affidavit, and your KYC identity file turn a claim into a sworn, identified, notarized act — the cornerstone of usucapião extrajudicial.

The publication establishes open and notorious possession

The 24-month edital and its hash-chained publication archive prove your claim was aired openly and left contestable — and that the record can't be backdated.

The commitment establishes função social

Your 25-year work commitment and development plan show intent to actually use the land — the principle that separates a real homestead from a paper trophy.

The continuity ledger keeps it alive

Monthly and annual attestations maintain unbroken, continuous possession — and the assignable instrument (escritura de cessão de direitos) lets you transfer the claim, just as Brazilian law lets you transfer posse before title exists.

Mandatory in every file: a notarized identity (KYC) record and a Declaration of Treaty Compliance & Non-Sovereignty — so the file is honest on its face and asserts no national sovereignty over any celestial body.

Important legal disclaimer

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; not legal advice. We model the process on frameworks in which documented good-faith possession was sometimes later recognized, but we do not guarantee any authority will ever recognize your claim. No Spaceclaims claim asserts national sovereignty. Nothing here is legal, tax, or financial advice.
