Hungarian domains can be registered by private individuals or companies in the EU. However, the administrative contact must have a residence in Hungary. deLink offers a trustee service for this, which is included in the domain price for .hu-domains and .co.hudomains is included. A paper form is always required for the application.
If this is too much work for you, if you don't want to use a trustee or if your Hungarian domain of choice is already taken, here is a real alternative: fast, cheap and without restrictions: hu.net or .hu.com!
