How does one take care of matters that is across oceans and continents? How does one make sure things are in order in a different time zone and will remain so?
For me, the best way is to dedicate a few hours a week to look into these matters. Keep the communication lines open with trusted contacts in the other time zones.
One step at a time, one thing at a time. Before you know it, a property is sold, your life insurance is paid, the money is transferred, your dormant post box revived, and so on and so forth.
