Summary In this paper, it is shown that all expected lifetimes ofh-processes inD are finite if and only if the area ofD is finite ifD={(x,y):ø_(x)〉y〈ø+(x), − ∞〈x〈∞}, where ø_(x)〈ø+ are two Lipschitz functions. We show that if Ω is a bounded convex region in the plane, there is anh-process in Ω with expected lifetime at leastc area (Ω). We also give an example of a planar domainD of infinite area such that the expected lifetime of eachh-process inD is finite.
