# SignatureField Class

> An instance of the SignatureField class represents a signature field in a Text Control document. A signature field is a frame which can be inserted in a document and that acts as a site for a signature image. An image can be added, when the document is designed or later when it is digitally signed. When the document is saved as a .pdf document, each signature field can be associated with a digital certificate using the SaveSettings.SignatureFields property.
