Parents must also keep a copy of all documents. Temporary guardianship comes into effect on the day all necessary parties sign the document and automatically expires six months after that date if no date is provided. If, after six months, guardianship is still required, the parties may sign another provisional guardianship agreement or apply for permanent guardianship through the court. It may be valid for schools, medical and dental care if only one parent signs it and has a custody regulation. .
