Where is the land mentioned? Is there no land registry there? In many jurisdictions, titles to land are registered through a government operated registry where would-be buyers could look up information on the situation of the land rights.

AFAIK you don't need to be a title company to do this, any buyer could do it themselves.

And what if you don't know enough about land law to make sense of everything? That's when you need companies to do it for you.

Is checking the chain of ownership of cryptocurrencies easier than land? It depends whether you're talking to a real estate lawyer or a NFT seller.

I'm neither, and I don't see the intrinsic difference.
