Navigating Your Credit Titling Workflows

Resolving Access and Documentation Challenges in STN

⚠️ Unable to Access Account (Forgot Password)

Cause: The notary has forgotten their system password.

Solution: While specific STN password recovery steps for notaries are not explicitly detailed, the general Infonavit process involves using a 'Forgot your password?' option. Typically, this requires entering identifying information like a social security number (NSS) and then verifying identity via a registered phone number or email to receive a password reset link. If this option is not readily available within the STN login interface, contacting the Gerencia de Administración del Aliado Estratégico en Titulación at Infonavit is the recommended course of action for notaries.

⚠️ Documentation Upload Issues (CLG Errors)

Cause: Documents, particularly the CLG (Comprobante de Libre Gravamen), are repeatedly uploaded incorrectly or fail validation more than three times.

Solution: The system is designed to prevent further advancement in the titling process if documentation errors persist. If a CLG is deemed incorrect by Infonavit after multiple attempts, the system will block progress, requiring the credit to be reinscribed. This highlights the importance of meticulous document preparation and adherence to all submission guidelines to avoid significant delays.

⚠️ System Unavailable Message

Cause: Experiencing a message like 'Por el momento el servicio no se encuentra disponible, intenta más tarde' (Service currently unavailable, please try again later) often indicates temporary platform difficulties, scheduled maintenance, or server issues.

Solution: This is usually a temporary situation. The best approach is to wait for a period and then attempt to access the system again.

Key Inquiries for Notaries Using the STN Portal

Q: What is the primary function of the Notarial Titling System (STN) for Infonavit notaries?

The STN's main purpose is to enable notaries collaborating with Infonavit to efficiently register, manage, and track the entire process of formalizing and titling housing credits. It ensures all documentation and stages of credit formalization are handled systematically, leading to property inscription in the Public Registry of Property (RPP).

Q: How does the STN portal evaluate a notary's performance?

The STN system feeds into the INEX Notarios (Notary Excellence Index), an automated evaluation tool. INEX assesses notary performance based on criteria such as the timely delivery of credit files to the National Archive of Credit Files (ANEC) and the correct, complete integration of those files, taking into account service levels for each federal entity.

Q: Where can a notary find the official operational manual for the STN system?

Notaries can find the comprehensive Manual del Sistema de Titulación Notarial directly within the Infonavit website, specifically on the page dedicated to notaries under 'Aliados Estratégicos' (Strategic Allies). This manual provides all necessary elements to operate the STN effectively.

Q: What information is needed to search for a credit within the STN?

To search for a specific credit within the STN, you primarily need the Número de Crédito (Credit Number). This allows notaries to locate and manage the titling process for individual beneficiaries.

The STN Infonavit portal is an indispensable digital solution for notaries, streamlining the intricate process of housing credit titling. By leveraging this system, notaries play a critical role in ensuring that Infonavit beneficiaries can successfully formalize their homeownership dreams.
