27 CFR § 73.33
Am I legally bound by a form I sign electronically?
April 24, 2020
Yes; by electronically signing a form you submit to us, you are agreeing to be legally bound to the same extent as if you applied a traditional handwritten signature on a paper document submitted to satisfy the same requirement. Persons using electronic signatures shall, upon TTB's request, provide additional certification or testimony that a specific electronic signature is the legally binding equivalent of the signer's handwritten signature.
