  The baryon structure is investigated in a covariant diquark-quark model. In
this approach baryons emerge as relativistic bound states of a constituent
quark and a $0^{+}$ or $1^{+}$ diquark. After solving the Bethe-Salpeter
Equation for the scalar diquark quark system in ladder approximation we couple
various external currents to the constituents of the baryon to probe its
internal structure. The quark and the diquarks are assumed to be confined which
is implemented by suitable choices for the propagators. This leads to
nontrivial vertex functions between the constituents and the external current.
Baryonic matrix elements are then evaluated to extract observable formfactors.
