Abstract. Let $T$ be a measurable map on a Polish space $X$, let $Y$ be a non trivial subset of $X$. We give conditions ensuring existence of conditionally invariant probability measures (to non absorption in $Y$). We also supply sufficient conditions for these probability measures to be absolutely continuous with respect to some regular measure.
