In Brazil, it is possible to proceed with voluntary registrations which may help your clients to solve disputes that can be raised in the country.
A copyright is valid for 70 years from January 1st of the following year of the author’s death. In the case of multiple authors, such a period is counted from the death of the last surviving author.
