A petition template typically contains a space to enter the subject matter and requested action of the document as well as subsequent spaced lines for signatories. The configuration of these two components varies from one template to another; examples are available on TidyForms.com and SampleTemplates.com.
The information portion of a petition addresses the nature of the document. It generally consists of the subject matter, which addresses the problem the petition concerns. The action of the petition suggests changes to rectify the problem.
The signatory space allows people who support the petition to sign their names. This area of the template typically also includes columns to note the date and the printed name of the signatory. Space for contact information, such as an mailing address, telephone number or email address, is also usually included.
