  This whitepaper describes how the VLASS could be designed in a manner to
allow the identification of candidate dual active galactic nuclei (AGN) at
separations <7 kpc. Dual AGN represent a clear marker of two supermassive black
holes within an ongoing merger. A dual AGN survey will provide a wealth of
studies in structure growth and gravitational-wave science. Radio wavelengths
are ideal for identifying close pairs, as disturbed stellar and gaseous
material can obscure their presence in optical and shorter wavelengths. With
sufficiently high resolution and sensitivity, a large-scale radio imaging
survey like the VLASS will uncover many of these systems and provide the means
to broadly study the radio properties of candidate dual systems revealed at
other wavelengths. We determine that the ideal survey for our purposes will be
at as high a resolution as possible, with significantly more science return in
A array at L-band or higher, or B array at C-band or higher. We describe a
range of potential survey parameters within this document. Based on the
analysis outlined in this whitepaper, our ideal survey would create a catalogue
of $\gtrsim$100 dual AGN in either: 1) a medium-sensitivity (~1 mJy detection
threshold), wide-field (few thousand square degree) survey, or 2) a
high-sensitivity (~10 uJy threshold) survey of several hundred square degrees.
