In an era where digital transformations and complex crises have challenged the traditional foundations of the document registration system, resilience has become a critical factor for the survival and growth of these institutions. Addressing this vital need, this research aims to design a resilience model for notary public offices in the age of fourth-generation services (smart, integrated, and transformative). The study employs a mixed-methods approach (qualitative-quantitative). In the qualitative phase, the meta-synthesis method and the Delphi technique were used with the participation of 15 experts holding at least a master's degree and 10 years of work experience, selected through purposive sampling. SPSS and Excel software were utilized to identify the initial dimensions of the model. In the quantitative phase, data collected from 180 professionals in the field were analyzed using Confirmatory Factor Analysis (CFA) and Partial Least Squares (PLS) regression in Smart PLS software. The findings of this research include 28 indicators across three dimensions: the organizational dimension (five indicators), the social dimension (seven indicators), and the technological dimension (sixteen indicators). As a practical solution, the establishment of an open registration innovation center was proposed to enhance resilience through collaboration with technology stakeholders.
