We investigate the Dirichlet problem for the parablic equation

in a non-smooth domain tex2html_wrap_inline61. In a recent paper [U.G.Abdulla, J. Math. Anal. Appl., 260, 2 (2001)] existence and boundary regularity results were established. In this paper we present uniqueness and comparison theorems and results on the continuous dependence of the solution on the initial-boundary data. In particular, we prove tex2html_wrap_inline63-contraction estimation in general non-smooth domains.
