Abstract	In both forensic and occupational identification, lateral palm prints—collected from the outer portion of the palm spanning the hypothenar area to the wrist—are still largely underutilized. The lateral region of the palm has been largely overlooked, even though it possesses unique dermatoglyphic and structural features, while traditional identification techniques have primarily focused on fingerprints and full palm print analysis. This study aims to highlight the often-overlooked value of lateral palm prints by analyzing crease formations, individual-specific features, and class traits associated with different occupational groups. A total of fifty lateral palm print samples were collected, with ten individuals representing each of the five occupational categories: construction workers, field laborers, bankers, drivers, and police personnel. The study conducted an extensive examination and comparison of ridge patterns, crease structures, and friction skin features specific to different occupational groups. Results show that the sort of repeated hand movements used in various jobs has a discernible impact on the lateral palm areas' structural development. For example, jobs that require physical labor often showed more prominent or irregular crease patterns, whereas desk-based occupations generally retained clearer and more delicate ridge features. The patterns influenced by a person’s occupation add to the uniqueness of the lateral palm and serve as a supplementary means of identification, which is particularly helpful in forensic scenarios where prints are partial or unclear. According to the results, lateral palm prints are a valuable but sometimes disregarded tool for improving the accuracy and thoroughness of personal identification methods. Keywords: examination of ridge flow patterns, lateral palm impressions, methods of forensic identification, occupational impact, individual characteristics, class-level features, crease formation, and detailed ridge structures.
