I create my title blocks as separate drawings for each size of paper (A, B, C, A4, etc.) which include everything I will use again including company name, scale, date, etc and a border. I then insert them in Paper Space by accessing them via the Symbol Library and center them in the paper. For A size, I center at 5.5,4.25. I then explode and edit any text and then I'm set. It's also a good idea when you create your title blocks in the original drawings to put everything on its own layer such as "title" that way when you insert them, you can easily turn the title block on or off.
