We consider a smooth system of ordinary differential equations in a neighborhood of a trivial solution. A system is assumed to have first derivatives with respect to phase variables. The Jacobi matrix is assumed to be H\"ol\-der continuous. We show that the well-known Lyapunov theorem on conditional stability remains valid for such systems.
