This research presented a microscopic and statistical examination of handwriting characteristics. Two handwriting specimens were involved which are normal and disguised handwriting specimen forms. The normal handwriting of 60 respondents were examined and classified into class characteristic (script types, letter size, slant, angularity alignment and word spacing) and individual characteristic of letters a, e, g, y, d, f, h, o, E and D and grapheme th. The other set of 50 handwritings were requested for comparison between disguised and normal handwritings. A statistical technique known as Pearson Chi-squared (χ 2 ) test was performed to determine the relationship between race, gender, age, first education system, education level and occupation with the normal habits of handwriting. The results showed that the handwriting can be uniquely classified (χ 2 <0.05). Only alignment and word spacing were not affected. During disguising their own handwriting, respondents tend to change the letter size, slant, initial capital letter and the speed of the writing, while the word spacing became inconsistent.
