This Practice Direction provides guidance for using the Part 19 procedure for certain family court applications. It outlines what types of applications must or can use the Part 19 procedure, how applicants and respondents should submit documents, and how the court will manage the applications. Key points include that the Part 19 procedure must be used for applications regarding adopted persons' information or fathers without parental responsibility, can be used if no prescribed form or if the application involves no substantial factual disputes, and involves submitting evidence with initial filings or within defined time periods.
