This could save your life if you are kidnapped or abducted.
A Proof of Life is a document that contains confidential information that can be used to confirm whether a person is still alive in case of kidnapping, abduction or detention. It can also be used to detail how that person would like their family members to be informed and/or if they have any special requirements, should something happen to them.
The person entrusted with this document (usually your key contact) will be responsible for communicating information with a lot of different people in the eventuality that you’re being held against your will. Giving them this information before you go on assignment will help them respond quickly and confidently, should something happen, and also help those who are trying to get you to safety.
