When applying for a guardianship order or intervention order, the application you need to complete and submit to the sheriff court is called a 'Summary Application'. There is no standard form as such. A basic 'style' or template to be followed is provided for in legislation. The style, and examples summary applications, are reproduced at Appendix 3 of our publication " Guardianship and Intervention Orders - making an application: A guide for carers".
The examples are for illustration only. You will need to tailor your application to reflect the circumstances of the adult concerned. Your local Citizens Advice Bureau or voluntary organisation (see Appendix 5 of the "Guide for carers") may be able to help.
