Topical issues of handwriting analysis of signatures performed with a significant gap in time

At the present stage, objects of forensic handwriting analysis are signatures performed with a significant gap in time. In this case, such both studied documents, made at different intervals and relation to comparative material time gap.
 Establishing stability signature signs depending on performing is possible taking into account characteristic stages formation. Since factors causing changes lengthy process forming skill amount practice (that how often person has sign). While research that formation signs, established together coinciding canindicate further improvement movements. personsof middle age (30-60 years old) who have formed handwriting, do not occur over until they stop practicing writing. elderly people along differing ones appear: ataxia, decreased coordination movements, low coherence written etc. These indicate degradation movements due physiological body old decrease writing including signature.
 Considering above, rather complicated causes difficulties when expert evaluates revealed signs. Within framework paper, authors focused some topical issues existing modern analyses The state development practical studies requires methodological approaches type research. Currently, experts conducting R&D topic: “Improving methods time” which relevance need improve algorithm while time, as well requirements scientific standards.
