Sažetak
The most common question that a handwriting expert is confronted with is to determine whether or not the signature or handwriting in question is authentic or forged. Moreover, in many cases, the request is to determine if the date on the document is the actual date the document was created or if the document has been backdated.
Two methods of examination can be applied for the latter: the ink dating method as a destructive method or the signatures and handwriting dating method as a non-destructive method.
This case study aims to show the changes that occur in a person's signature over time.
During the secret investigation phase, the Croatian State Prosecutor's Office for the Suppression of Organized Crime and Corruption sent the Forensic Science Centre two Annexes to professional playing contracts containing two signatures in the name of Luka Modric. The experts were asked to determine if the questioned signatures were authentic and other facts relevant to the investigation (backdating etc.).
The results obtained have shown clear variations/developments in known signatures over time without applying any destructive method.
