# Form and case report book signatures

The InForm application allows you to configure studies so that your signature is attached to a single form, several forms, or an entire case report book. For example, a study can be configured to require a signature on certain key forms for each subject and also to require a signature on the case report book for each subject.

When a study is set up, specific forms are designated as signing CRFs. Additionally, if signing is required for a complete case report book, a single form is designated as the signing CRF for the case report book.
