Tex. R. Sup. Ct. 6

As amended through August 27, 2024
Rule 6 - Signatures on e-filed documents
(a) Except as otherwise provided by this rule, the confidential, secure username and password that the e-filer must use to e-file a document constitute the e-filer's signature on the document, in compliance with signature requirements in the Texas Rules of Appellate Procedure. When a signature is provided in this manner, the e-filer must also include either an "/s/" and the e-filer's name typed in the space where the e-filer's signature would otherwise appear or an electronic image of the e-filer's signature, which may take the form of a public key-based digital signature or a scanned image of the e-filer's signature. The efiler must not allow the e-filer's username or password to be used by anyone other than an agent who is authorized by the e-filer.
(b) If a document must be notarized, sworn to, or made under oath, the e-filer must e-file the document as a scanned image containing the necessary signature(s).
(c) If a document requires the signature of an opposing party, the e-filer must e-file the document as a scanned image containing the opposing party's signature.
(d) When an e-filer e-files a scanned image of a document pursuant to paragraph (b) or (c) of this rule, the e-filer must retain the original document from which the scanned image was made until the case in which the document was filed is resolved. If the original document is in another party's possession, that party must retain the original document until the case in which the document was filed is resolved.
(e) If an e-served document was also e-filed and the person who completes a certificate of service under Texas Rule of Appellate Procedure 9.5(e) is different from the person who e-filed the document, the person who completes the certificate of service must sign the certificate by including either an"/s/" and his or her name typed in the space where his or her signature would otherwise appear or an electronic image of his or her signature.
