During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee.

The official blazon is "Vert, three acorns in pall stems conjoined Or" (Norwegian: I grønt tre gull eikenøtter i trepass).

This means the arms have a green field (background) and the charge is a cluster of three acorn with their stems connected.

The charge has a tincture of Or which means it is commonly colored yellow, but if it is made out of metal, then gold is used.

There are three acorns to represent the three main population centres in the municipality (Moi, Hovsherad, and Ualand/Heskestad).

The tables below show the current and historical composition of the council by political party.

The lake Hovsvatnet lies in the central part of Lund, north of Moi.
