We analyze theories in which a supersymmetric sector is coupled to a supersymmetry-breaking sector described by a nonlinear realization. We show how to consistently couple N=1 supersymmetric matter to nonsupersymmetric matter in such a way that all interactions are invariant under nonlinear supersymmetry transformations. We extend this formalism to couple N=2 supersymmetric matter to N=1 superfields that lack N=2 partners but transform in a nonlinear representation of the N=2 algebra. In particular, we show how to couple an N=2 vector to N=1 chiral fields in a consistent way. This has important applications to effective field theories describing the interactions of D-brane world-volume fields with bulk fields. We apply our method to study systems where different sectors break different halves of supersymmetry, which appear naturally in models of intersecting branes.
