The author considers the generalized Cauchy-Riemann system with nonlinear terms $$\partial u/\partial\overline{z}_j-\overline{a_j u}=f_j$$, $$j=1,\dots, n$$, in an arbitrary domain of the complex space. Under some natural conditions on the coefficients and compatibility conditions, the author proves solvability of this system in the space of locally square integrable functions.
