In this paper we prove a generalized version of Hall's theorem in graphs, for hypergraphs. More precisely, let $\mathcal{H}$ be a $k$-uniform $k$-partite hypergraph with some ordering on parts as $V_{1}, V_{2},\ldots,V_{k}$ such that the subhypergraph generated on $\bigcup_{i=1}^{k-1}V_{i}$ has a unique perfect matching. In this case, we give a necessary and sufficient condition for having a matching of size $t=|V_{1}|$ in $\mathcal{H}$. Some relevant results and counterexamples are given as well.
