Hi Jilius, 

Thank you very much for your reply. It is a good idea, but the latex class I am using (entcs) has its own \title and \date, and by renewing the command I overwrite both... 

I am removing these lines by hand from the tex file generated by the export engine... but it is not nice. Any help is very much appreciated!

Best regards, 
Flávio.
 
Hi  Flávio,
perhaps you could add something like (untested)
#+LATEX_HEADER: \renewcommand{\title}[1]{} \renewcommand{\date}[1]{}
to your org-file? It's not exactly what you asked for, but it might
alleviate your problem.
HTH,
Julius
