What Is Chain of Custody?
Chain of Custody is a documented record showing how physical or digital evidence moved from collection through storage, review, and presentation. The record identifies each person who handled the evidence, the transfer or access, and the condition of the item. In medical malpractice claims, this process helps establish that evidence remained authentic and unchanged.

Key Takeaways About Chain of Custody
- A handling record links evidence to each person who possessed it.
- Clear transfer details help authenticate records, devices, photographs, or samples.
- Chain of custody is not the same as medical record accuracy.
How Chain of Custody Works

Chain of Custody begins when a person collects or receives evidence connected to a claim. The record identifies the item, its source, its condition, and each later transfer or access. Digital evidence may include access logs, while physical evidence may require storage records and sealed packaging.

Medical records, device data, photographs, and retained specimens can follow separate custody records. Each entry should connect the evidence to the person who handled it and explain where the evidence went next. A medical record may describe treatment, while an expert witness may review the record and explain its significance. Gaps can create questions about authenticity, alteration, or completeness.

From the Atlanta Auto Law team
When we review medical malpractice evidence, we trace who collected, stored, transferred, or examined each item. We compare custody records with medical records, device information, and witness accounts. That review helps us identify questions about authenticity before evidence is presented.
Chain of Custody in Practice: A Real-World Example
A hospital retains a device connected to a patient’s treatment, and the device later becomes evidence in a medical malpractice claim. The custody record identifies the person who secured it, each transfer, and the condition recorded at each stage.
