Many courts allow electronic signatures but each court has different requirements on what needs to be included for an electronic signature.
The eFile site will not allow you to sign your document(s). However, in 3rd party programs such as Microsoft Word, you can use the electronic signature of /s/ Your Name and underline, then save to add an electronic signature. You may also sign the document(s) electronically via www.ILovePDF.com.
Otherwise, you can still wet sign (in Ink) the original document and scan back to your device prior to uploading on the site.
Note: For questions regarding the acceptance of a signature on a document, please refer to the court you are filing in for assistance.
