Is it compulsory to file the trademark application form by means of an IP Agent or another legal representative in Argentina?

According to the Argentinean trademark Law, it is not compulsory to appoint neither an IP Agent nor a legal representative. Nevertheless, the requirement to have a domicile based on the Federal Capital (which is also required for Argentinean applicants) entails appointing a local legal representative if the company intending to register a trademark in Argentina does not have a domicile there.
