My girlfriend and I are planning a dive trip (her first) to Coz in June. One of her concerns is what happens if she is in some sort of accident (non-fatal) and is unable to make medical decisions for herself while in a foreign country (like Mexico). I am sure they will try and contact her next-of-kin at some point, but sometimes in a life or death situation, time is critical. She wants me to be able to take action on her behalf so should we get a medical power of attorney before leaving or how should we best handle that?
