This phase begins when a request for examination is received. It involves preparing all of the paperwork and forms required to document chain of custody, ownership information, device model, purpose, information that the requestor is seeking, and so on. Chain of custody refers to the chronological documentation or paper trail, showing the seizure, custody, control, transfer, analysis, and disposition of physical or electronic evidence. From the details submitted by the requestor, it's important to have a clear understanding of the objective for each examination.
