A deed needs an authority behind it
Buying land on Earth works because a chain of laws and institutions can recognize who owns a parcel, record a transfer, and help enforce the owner’s rights. A seller can hand over a document, but the document matters only because a legal system gives it force.
There is no comparable system for lunar land. The 1967 Outer Space Treaty says that nations cannot claim the Moon as their territory, whether by declaring sovereignty, occupying it, or otherwise. Without a recognized national owner, no government can straightforwardly divide the Moon into parcels and issue deeds.
The unresolved question of private claims
The treaty’s ban is written around countries, while companies and individuals are not countries. But that wording does not create a recognized path for private lunar ownership. The treaty also makes countries responsible for supervising their citizens’ and companies’ space activities. It does not establish a lunar land registry or explain how a private claim would be recognized and enforced.
That leaves an important distinction: a company may sell a certificate describing a plot, but the certificate is not the same as a title backed by law. There is no settled legal framework that makes the buyer’s claim binding on other people, governments, or future lunar operators.
What a lunar “purchase” can promise
A novelty deed can still serve as a gift or keepsake. What it cannot reliably deliver is the practical bundle that ownership provides on Earth: the right to exclude others, transfer a legally recognized title, or turn to a court or government to enforce it. Until countries establish rules that address those rights, a plotted crater on a certificate remains a claim on paper—not land the buyer can legally control.
