All the court filings I've ever made electronically I've used the (stupidest fucking) system, which is called Conformed Signatures. You basically just type your name and put "s/" in front of it. That's supposed to tell the court you've got an original signed in pen and ink stashed in a drawer somewhere, but the reality is that no lawyer I know of actually has such a thing.

I've never actually seen a proper esignature in a court document. Most court record systems are so outdated that it's honestly an enormous win if they allow you to view, upload or download documents over the web at all.
