An Illinois Order Dismissing Petition For Guardianship is an official court document issued by a judge that terminates the legal guardianship of an incapacitated adult or minor. This type of order is typically issued when the court finds that the guardianship is no longer necessary or appropriate for the protected individual. There are two types of Illinois Order Dismissing Petition For Guardianship: With Prejudice and Without Prejudice. An Order Dismissing With Prejudice is a final ruling which prevents the filing of a similar guardianship petition in the future, while an Order Dismissing Without Prejudice allows for the filing of a new guardianship petition in the future. In either case, the Order Dismissing Petition For Guardianship must be approved by the court in order to be valid.
