We present the first calculation on the $\Delta$ axial-vector and
pseudoscalar form factors using lattice QCD. Two Goldberger-Treiman relations
are derived and examined. A combined chiral fit is performed to the nucleon
axial charge, N to $\Delta$ axial transition coupling constant and $\Delta$
axial charge.
