Abstract: It is shown that the determinant line bundle associated to a family of Dirac operators over a closed partitioned manifold $M=X^{0}\cup X^{1}$ has a canonical Hermitian metric with compatible connection whose curvature satisfies an additivity formula with contributions from the families of Dirac operators over the two halves.
