The Illinois Petition for Modification of Allocation of Parental Responsibility is a form used by parents in Illinois to modify existing court orders regarding the allocation of parental rights and responsibilities. This petition is typically filed when one parent wants to modify an existing parenting plan, such as to change physical custody or parenting time schedules. The petition must be filed in the circuit court of the county in which the child lives or in which the original court order was entered. There are two main types of modifications that can be requested through the Illinois Petition for Modification of Allocation of Parental Responsibility. The first is the request for a major modification, which is a request to change either the physical custody or the parenting time schedules of the existing court order. The second is the request for a minor modification, which is a request to change any other provision of the existing court order, such as the child support amount or the responsibilities of each parent. In order to file an Illinois Petition for Modification of Allocation of Parental Responsibility, the petitioner must include the following information: the names and addresses of the petitioner and the respondent, the case number, the date of the original court order, the proposed modification, a statement of facts in support of the proposed modification, and a statement of the petitioner's reasons for requesting the modification. The petitioner must also include a copy of the existing court order and any other relevant documents.
