How does a person be declared competent after being declared incompetent?

A person previously declared incompetent can be deemed competent again through a legal process that typically involves a mental health evaluation by qualified professionals. This evaluation assesses their cognitive abilities, decision-making skills, and overall mental state to determine if they can understand and manage their personal affairs. If the findings support a change in status, a court may then issue a ruling restoring the individual's competence. Additionally, the individual may need to demonstrate their ability to manage their own affairs effectively over time.
