This study explores the implementation of administrative services in Pandanwangi Village, Blimbing Sub-district, Malang City, following the enactment of Mayor Regulation No. 110 of 2019 concerning the delegation of part of the mayor's authority to sub-district heads. Despite a standardized legal framework and supporting infrastructure, the implementation process faces multiple challenges, particularly in terms of procedural complexity, human resource limitations, and ineffective coordination. Using a qualitative descriptive approach, this research analyzes the mechanisms, supervision, and effectiveness of administrative services, especially in processing heirship documents. Findings reveal that service delivery remains hindered by overlapping duties among officers, unclear delegation of authority, insufficient staff training, and an excessive workload among a small team of eight officers handling 28 delegated tasks. Additionally, socialization efforts remain weak, relying heavily on neighborhood intermediaries, leading to public confusion and delays. Budget constraints and legal costs further burden low-income residents. However, the availability of infrastructure such as computers, internet access, and adequate physical facilities contributes positively to the service process. Recommendations include simplifying service procedures, enhancing coordination structures, strengthening direct community engagement, allocating government support funds, and building human resource capacity through training and task redistribution. The expected impact of these improvements is to enhance the efficiency, responsiveness, and transparency of administrative services in Pandanwangi Village, ultimately contributing to greater public trust and social equity in public service delivery.
