To file a maintenance case under Section 125 CrPC in India, the aggrieved person (usually wife, child, or parents) must submit an application to the Magistrate of the first class in the jurisdiction where she or they reside. The application should state facts showing neglect or refusal to maintain. After review, the court may summon the respondent and conduct a hearing before granting monthly maintenance if justified. https://lawyerinnoida.com/maintenance-of-dependents/
