Purpose: The central purpose of the research is to explore and determine how the intestate succession process influences legal security in Peruvian notaries' offices. Although the theoretical framework is not explicitly stated, it can be inferred that it focuses on notarial management, legality, and legal security, as well as the intersection of technology and data science with law. Theoretical framework: The importance of notarial management, legality and legal certainty in intestate succession proceedings is mentioned, as well as the relevance of technology and data science in the legal field. Design / methodology / approach: In terms of design and methodology, the research is applied and has been carried out through a non-experimental design, specifically cross-sectional, descriptive, and correlational. A total of 30 lawyers have been surveyed, exploring the variables intestate succession process and legal certainty. Results: The results indicate that both variables are regular, with 63% each, and a strong positive correlation between them was identified, with a Spearman's Rho of 81.5% and a p-value of 0.001, which allows us to accept the alternative hypothesis. Research, practical and social implications: From a practical and social perspective, the research underlines the critical importance of meticulous and efficient notarial management, which not only protects clients' rights, but also ensures fair redress in case of inconvenience, weaving a blanket of legal security around all parties involved. We envision a future in which technology and data science intertwine with law, creating predictive models and automated systems that optimize notarial processes and anticipate potential problems in probate proceedings. Originality / value: In terms of originality and value, the research stands out not only for illuminating the correlation between intestate succession procedures and legal certainty, but also for highlighting the need for meticulous and efficient notarial management. Moreover, it opens a window to a horizon where technology and data science merge with law, and where academia becomes a melting pot for future legal professionals, linking academic knowledge with society through didactic material and online learning platforms, illuminating the nooks and crannies of probate law and empowering the public.
