56. A person must be able to fully exercise his rights to be a party to an action in whatever form it may be, saving contrary provisions of law.
A person who is not able to fully exercise his rights must be represented, assisted or authorized, in the manner provided by the laws which govern his status and capacity or by this Code.
The irregularity resulting from failure to be represented, assisted or authorized has no effect unless it is not remedied, and this may be done retroactively at any stage of a case, even in appeal.
