The author introduces some Hardy spaces associated with a rearrangement invariant Banach function space and containing all càdlàg processes, all adapted càdlàg processes and all martingales, respectively. The duals of these Hardy spaces are characterized and so some duality results from the books of \textit{A. M. Garsia} [``Martingale inequalities. Seminar notes on recent progress'' (1973; Zbl 0284.60046)] and \textit{C. Dellacherie} and \textit{P.-A. Meyer} [``Probabilities and potential. B: Theory of martingales'' (1982; Zbl 0494.60002)] are generalized.
