Chain of Custody Law & Legal Definition

Chain of custody is a process that must be followed for evidence to be legally defensible (acceptable to courts and government agencies). It involves these main elements:

* The evidence collector properly identifies the evidence.

* The evidence collector must be a neutral party who has no personal interest in the test results (e.g., a hospital, clinic, or laboratory staff person).

* The evidence collector tamper-proofsand secures evidence at the collection site.

The following is an excerpt from a state statute dealing with chain of custody:
