Contract Services strongly recommends the use of digital signatures to fully execute agreements in place of a wet signature. TxDOT currently uses DocuSign, digital signature-as-a-service software that can be used to create and obtain secure digital signatures. If you have questions about the uses of DocuSign, please contact Contract Services at 512-416-4620. For all other DocuSign inquiries and technical support, please contact Information Management Division at 512-302-4357.
