Never been a paralegal, but I did teach legal writing in a paralegal program one semester. I've been a lawyer and a legal secretary. I'd guess that paralegal duties would be similar in any of the former British colonies - where we have the common law system - but don't really know!

Really, in the USA, paralegal duties vary HUGELY depending on the specialty and the firm's needs. It's usually just part of the same work a lawyer would ordinarily do - which could be interviewing clients, investigation, title searches, legal research and memo writing, drafting court documents, correspondence, and just about anything else you can think of, probably excepting negotiations, but some paralegals might even do that?
