Alongside complete certified medical records, preferably accompanied by a certification letter, the death certificate and any autopsy, pathology, toxicology, or forensic reports may be important. Their usefulness depends on the medical questions presented.
If the death is recent and the cause is uncertain, promptly ask the relevant professional or institution about an autopsy's availability, requirements, and cost. Keep the request and explanations. This is a sensitive decision dependent on the circumstances and the person authorized to decide.
An autopsy may help evaluate causation but does not itself prove negligence. Its absence does not automatically rule out a claim. Review requires consideration of all available information.
The answer for your situation depends on the facts and records. An inquiry does not suspend legal deadlines or guarantee that the office will accept the case.
