Nowadays, one of the issues of concern that brought on by the aging population is legal disputes that have been increasing in number every year. One core problem in these legal disputes involves handwriting identification. There are however not many previous studies in China that have been concentrated on this field. Hence, the study on elderly Chinese subjects' handwriting has an extremely broad potential value for its application for academic usage and practical meaning. This study uses an empirical technique, gathering first hand data and analysing them by employing proper methods. There are 7 handwriting features and characteristics that have been found in the study to represent the key characteristics of the elderly Chinese subjects' handwriting. They are: Pen pressure, occurrence rate of traditional Chinese words, letter size, poor structure, tremor, half-way stop sign, and towing sign at beginning and end of strokes.
