Abstract: The renormalization, finiteness and off-shellness of short distance powerlike singular interactions is discussed. We show analytically that therenormalizability of the off-shell scattering amplitude relies completely onthe corresponding on-shell amplitude without proliferation of new counterterms.We illustrate the result by complementary calculations both in coordinate aswell as in momentum space in the simplest 1S0 channel for chiral npinteractions including Two Pion Exchange.
