For a given linear system on a curve, the number of divisors of a certain type contained in this system is known as the formula of de Jonquières. In this paper, we give an algorithm for getting a general de Jonquières formula for a family of nodal curves. Using this algorithm we obtain one of such formulas for a particular case; on a single partition [Formula: see text] of [Formula: see text] for a one parameter family of nodal curves. Moreover we retrieve the classical de Jonquières’ formula for a single curve using the method developed in this paper.
