Let φ : C → C be an unramified morphism of plane affine curves defined over a number field K. In this paper we obtain a quantitative version of the classical Chevalley-Weil theorem for curves giving an effective upper bound for the norm of the relative discriminant of the field K(Q) over K for any integral point P ∈ C(K) and Q ∈ φ−1(P ).
