  We analyse a two-particle quantum system in $\R^d$ with interaction and in
presence of a random external potential field with a continuous argument (an
Anderson model in a continuous space). Our aim is to establish the so-called
Wegner-type estimates for such a model, assessing the probability that random
spectra of Hamiltonians in finite volumes intersect with a given set. For the
lattice version of the two-particle model, a similar result was obtained in [8]
