The register offices send copy series of these volumes to the county archives, or, in Budapest's case, to the municipial archives. Knowing the exact location and time of one of those three lifetime events, one can request photocopies from the archives. Keep in mind the personality law in Hungary though. If you need a record after these time borders, you have to request them at the consulates of the Republic of Hungary, worldwide. An other option is to give a commission to somebody on-site to request the extract.
