A precise knowledge of nucleon axial form factors is needed for the new generation of terrestrial neutrino experiments. Lattice QCD determinations of these form factors are particularly challenging due to contamination from excitations, in particular from 𝑁𝜋 scattering states. Transitions from a 𝑁 to a 𝑁𝜋, mediated by an axial current, are also interesting themselves, as these can be related to neutrino induced pion production, a process that is prominent in neutrino detectors. I will comment on the state of the art, discuss recent results and give an outlook regarding future prospects.
