What a careful buyer checks before paying for a domain

Most of a domain purchase goes right most of the time. The checks below exist for the minority of cases that do not, and every one of them is cheaper to run before payment than to discover afterwards.

Ownership and authority

1. Is the seller the registrant of record? Not the developer, not the agency, not the founder who has left. Ask, and verify against what the registrar record shows. This single check prevents the most common class of failed purchase.

2. Can they actually execute? A company registrant needs someone with authority to sign. A registrant who has restructured or dissolved has a problem that will become yours.

3. Is the name transferable now? Not locked, not inside a restricted window after a recent change, not so close to expiry that it should be renewed first.

History

4. What was on it before? Archive services show past versions of the site. A name that hosted an ordinary business is fine. A name that hosted spam, adult content or a scheme you would not want associated with your brand is a different asset from the one advertised.

5. Is it indexed? Search for the domain itself. A name with no presence at all is neutral. A name whose pages have been removed from search results is a warning.

6. Is it on any blocklist? Check the common email and security blocklists. A name with a spam history can be unusable for email for a long time, which matters more than people expect.

7. What links to it? A large volume of low-quality inbound links is a liability, not an asset. Anything that looks like purchased link-building is a reason to discount heavily or walk.

Legal

8. Does the term collide with a registered trademark? Search the relevant trademark registers for the markets you will operate in. A generic category word is normally safe; anything that reads as a brand needs checking before you pay, not after you launch.

9. Has it been disputed? Dispute decisions are published. A name with a history of complaints is a name someone believes they have a claim on.

The Vietnamese-specific checks

10. What does it say to a native speaker? The bare string, read cold, with no context. This is the one check that has no equivalent in an English-language purchase and the one foreign buyers skip most often.

11. Does the matching local extension exist, and who holds it? If you are buying the .com and someone else already trades on the .com.vn of the same word, you have a future conversation on your hands. Better to know its shape now.

How long this takes

Under an hour for a name you are serious about, and most of it is free. Set against the price of a premium domain and the cost of rebranding, an hour is not a meaningful expense — and the check that saves you will be one of the cheap ones.

The one thing not to skip under time pressure is the first. Everything else is about the asset; the first is about whether the person you are paying can deliver it.
