Apostille vs. Embassy legalisation for Hungary
Some countries still want a chain of offices, each one vouching for the last, ending at a consular desk. This one does not. A single British certificate closes the paper, and nothing sits behind it. An apostille issued in Liverpool for use in Hungary is finished the moment it comes back through the post, which is why the planning here is front-loaded: almost every choice that can go wrong is made before anything is sent.
Hungary's Hague status & what it means
Hungary joined the Hague Apostille Convention in 1973, so this route has been settled for the whole working life of anyone reading the page. There is no transition to watch, no cut-off date to diarise and no doubt about whether the certificate will be recognised. The stability shows up mainly as an absence: no extra form to fill, no second fee to find and no separate office to schedule around.
The Liverpool → Hungary route step by step
Liverpool Register Office holds civil records and can issue a fresh certified copy, so the record you keep at home stays where it is. The FCDO Legalisation Office at PO Box 6255, Milton Keynes MK10 1XX then adds the certificate on behalf of the whole United Kingdom. It runs by post, so there is no queue you can stand in and nothing to collect; the only thing moving is your paper's place in the pile.
Destination-specific requirements
The certificate is silent about Hungary, but the person waiting at the far end is not. That reader asked for a particular record, in particular names, covering particular dates, and no certificate can repair a mismatch in any of those. Read the original request word for word before choosing the sheet, because a perfect certificate on the wrong paper still sends you back to the start with the money already spent.
