Third Party Digital Signature with SignNow
Award-winning eSignature solution
What third party digital signature is
Third party digital signature is an eSignature workflow where a separate platform helps send, verify, capture, and store signatures for business records. In SignNow, the process usually includes document preparation, signer authentication, an audit trail with timestamps, and tamper-evident storage. In the U.S., this supports ESIGN and UETA use cases when the signer intends to sign and the record can be tied to that person.
Why third party digital signature matters
Third party digital signature reduces paper handling, speeds approval cycles, and preserves evidence for U.S. business records. Under ESIGN and UETA, it can support enforceable transactions when signer intent, attribution, and record integrity are documented.
How third party digital signature works
Third party digital signature follows a clear document flow, from preparation through signing, sealing, and archival, with each step recorded for later review.
Prepare: Create the document in SignNow and prepare the signature fields. Send: Send the signing request to each third party signer. Sign: The signer reviews, signs, and completes any required fields. Finish: SignNow seals the file, stores the audit trail, and archives it.

Business types that use third party digital signature
Different organizations use SignNow to remove paper delays while keeping approval records organized, searchable, and easier to review later.
Solo law offices use third party digital signature for engagement letters, NDAs, and client approvals, because SignNow supports reusable templates, mobile signing, and simple audit trails without adding heavy administrative work. Healthcare groups use it for intake forms, consent forms, and patient acknowledgments, because HIPAA workflows need access controls, audit trails, and BAA coverage when PHI is involved. Construction teams use it for bids, change orders, and site contracts, because field signers can review and sign from mobile devices without waiting for paper documents to return to the office.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.

FAQ about third party digital signature
These answers cover compliance, plan limits, document exclusions, and evidence issues that matter when third party digital signature is used in U.S. business workflows.
A signed file usually becomes admissible when the platform records signer identity, timestamps, and a tamper-evident audit trail. SignNow business plans include audit trails, templates, and mobile apps; HIPAA workflows also require a BAA.
For HIPAA workflows, SignNow can be used only with a signed BAA and appropriate access controls. HIPAA does not require a specific signature technology, but it does require audit controls, unique user identification, and integrity safeguards under 45 CFR 164.312.
ESIGN and UETA generally apply to business records, but wills and certain court orders remain excluded. If a form falls outside the statute, use the applicable paper or notarized process instead of relying on an eSignature workflow.
The Business plan includes audit trails, templates, and unlimited users. Business Premium adds bulk send and kiosk mode, while Enterprise adds advanced signer authentication and formula fields. Site License is the option for SSO and full API access.
If a signer says the record was changed, export the audit trail and signed PDF immediately. The time-stamped log, document hash, and action history help show when the file was opened, signed, sealed, and archived.
Mobile signing is valid under ESIGN and UETA when intent and attribution are clear. SignNow supports iOS and Android apps, so recipients can sign from phones or tablets without changing the legal status of the record.
