The forensic examination of handwriting remains a critical tool in legal and investigative contexts, particularly in the authentication of signatures. This paper explores the complexities associated with assisted guided hand signatures and non standard writing marks, including crosses, check marks, ballot markings, and rubrics. Through structural and behavioral analysis, the study identifies distinguishing features between genuine and fraudulent writing. Contrary to common assumptions, irregularities such as clumsiness and inconsistency may indicate authenticity in assisted signatures, while excessive smoothness and refinement often suggest forgery. The paper further evaluates legal considerations and methodological approaches, emphasizing the importance of line quality and motor coordination. The findings highlight the necessity of expert interpretation in forensic handwriting analysis.
