Abstract: A normal quasi-affine surface over an algebraically closed field of characteristic zero which has a $ {G_a}$-action is shown to have a geometric quotient if and only if the action is without fixed points. If the surface is factorial affine, and the action without fixed points, the surface is the product of a curve and $ {G_a}$.
