The complex scaled hyperspherical adiabatic expansion method is used tocompute momentum and energy distributions of the three $\alpha$-particlesemerging from the decay of low-lying $^{12}$C-resonances. The large distancecontinuum properties of the wave functions are crucial and must be accuratelycalculated. We discuss separately decays of natural parity states: two $0^+$,one $1^{-}$, three $2^+$, one $3^-$, two $4^+$, one $6^+$, and one of each ofunnatural parity, $1^{+}$, $2^-$, $3^+$, $4^-$. The lowest natural parity stateof each $J^{\pi}$ decays predominantly sequentially via the $^{8}$Be groundstate whereas other states including unnatural parity states predominantlydecay directly to the continuum. We present Dalitz plots and systematicdetailed momentum correlations of the emerging $\alpha$-particles.
