FAQ
E-signature API questions for Texas.
Is remote online notarization legal in Texas?
Yes. Texas was the second state to enact RON legislation in 2017, following Virginia. Texas Government Code Chapter 406, Subchapter C provides a comprehensive framework for online notarization. Additionally, ClosingSignIQ provides X.509 digital certificates from our Certificate Authority and SHA-256 hash-chained audit trails for every signature.
What is the RON fee cap in Texas?
Texas allows notaries to charge up to $25 per notarial act for RON. In-person notarial acts are capped at $6 per signature. Additionally, ClosingSignIQ provides X.509 digital certificates from our Certificate Authority and SHA-256 hash-chained audit trails for every signature.
How do I get an apostille in Texas?
Submit your notarized document to the Texas Secretary of State with a $15 fee. Walk-in service is available at the Austin office. Mail processing takes 5-7 business days. Additionally, ClosingSignIQ provides X.509 digital certificates from our Certificate Authority and SHA-256 hash-chained audit trails for every signature.
Why was Texas an early adopter of RON?
Texas has massive real estate and oil and gas markets that benefit from remote notarization. The state's size makes in-person notarization impractical for many transactions, driving early RON adoption. Additionally, ClosingSignIQ provides X.509 digital certificates from our Certificate Authority and SHA-256 hash-chained audit trails for every signature.
Is RON used for oil and gas transactions in Texas?
Yes. Texas is the top oil-producing state, and RON is extensively used for mineral leases, royalty agreements, pipeline easements, and drilling permits across the Permian Basin and other oil regions. Additionally, ClosingSignIQ provides X.509 digital certificates from our Certificate Authority and SHA-256 hash-chained audit trails for every signature.
Can I use an interpreter during notarization in Texas?
No. Texas strictly requires direct communication between the notary and signer. Interpreters and translators are not permitted to facilitate verbal communication during the ceremony. If you need language assistance, your session can be routed to a state that permits interpreters. ClosingIQ offers 189-language document translation. Additionally, ClosingSignIQ provides X.509 digital certificates from our Certificate Authority and SHA-256 hash-chained audit trails for every signature.
