Hello
Regarding Administration and two Administrators both claiming Administration and as the poster claims one was away at sea.
In the event of the deceased dying Intestate and it going to Admin. Like Executors, Administrator/s have a very responsible job, to do the administrative work, proper accounting of money collected in and expenses paid out, deal with property and follow the Laws of Distribution and any tax etc., including getting any advice.
Bear in mind I am not a Lawyer, but I am wondering if there was also a mechanism to publish a Notice in the London Gazette and the Local newspaper of where the deceased lived, or other newspaper of where the other Administrator was last known to reside, or be, where an Administrator disappeared and needed to be contacted?
