A deputy lieutenant of Aberdeenshire is commissioned by the Lord Lieutenant of Aberdeenshire.
The Lieutenancy Area of Aberdeenshire was previously known as the County of Aberdeen – not to be confused with the former County of the City of Aberdeen.
Deputy lieutenants support the work of the lord-lieutenant.
There can be several deputy lieutenants at any time, depending on the population of the county.
Their appointment does not terminate with the changing of the lord-lieutenant, but they usually retire at age 75.
