Texas Government Code - GOV'T § 51.806. Signature on Original

(a) If the supreme court determines that each document filed by electronic transmission must be signed in the original, that requirement is satisfied if the sending station at the point of origin maintains a hard copy with the original signature affixed that, on order of the court, shall be filed in original hard copy medium. The electronic transmission of the data to be filed must bear a facsimile or printing of the required signature. The signature may be represented in numerical form. The electronically reproduced document must bear a copy of the signature or its representation in numerical form.

(b) The electronically reproduced document shall be accepted as the signature document for all court-related purposes unless the hard copy with the original signature affixed is requested by one or more parties to a suit or other agent required by statute, law, or other legal requirement. A request under this subsection must be made in the form of a motion to the court. If the court grants the motion, the court shall order that the original be filed with the court.
