Én az U.S. igazságügyi minisztériuma által javasolt formátumot követem. Mások mást vesznek alapul.

There are obviously several alternatives as to how to write legal references like this, e.g. you can substitute Article for Section (or use either with small case first letters if you prefer). The main thing is to be consistent. One advantage of using Article is that it's good to reserve the word "section" for "pont", as in the "pont" of a contract. One advantage of adding is "para." (or "paragraph") is that the Hungarian uses "bek." or "bekezdés" (not here, because it's probably been cut off), so you can reflect that accurately in your translation and, importantly, if later in the text it just refers to e.g. "2. bekezdés" (without the §), you've got something you can use for that. That is why our company decided to adopt this form, and it was accepted by most the law firms we work with. Another way of doing it, is to look at the forms used in the "official" translation of the laws, though the only problem with that is that the Hungarian laws are not translated consistently (e.g. some use Section, and some use Article, and even the key terms in them are not consistent between the various laws). Hope that helps!
