In this guide , investigator Alexandre Ribeiro (LIDEPPE member no. 33) explains how the process for investigating matrimonial matters works and how the evidence obtained can be crucial for divorce proceedings and the regulation of parental responsibility.

Many attempt to conduct their own investigations by installing spyware or accessing private devices. Warning: These practices are illegal in Portugal.

A professional private investigator works within the legal framework and uses the following methods:
