The Washington Chain of Custody Declaration is a form used in Washington State to document the transfer of evidence in criminal investigations and criminal proceedings. It is used to document a chain of custody for all evidence, from the time it is collected until the time it is presented in court. The form is a document signed by an officer of the court and the custodian of the evidence, stating the evidence has been received and is in the custody of the custodian. The Washington Chain of Custody Declaration has two main types: original evidence and duplicate evidence. Original evidence is the actual evidence collected and must be kept in a secure environment to ensure its integrity. Duplicate evidence is a copy of the original evidence, and may be kept in a less secure environment. The Washington Chain of Custody Declaration form includes information such as the name of the custodian, the date the evidence was received, the type of evidence, the description of the evidence, the number of pieces, and any special instructions for handling the evidence. It also requires the signatures of the custodian, a witness, and the officer of the court.
