We grant the former wife’s petition for certiorari and quash the order requiring her to provide medical records showing when she became pregnant. We conclude that this was not a material fact which should have been disclosed to the former husband when he entered into the marital settlement agreement, where, as in this case, the parties had entered into a separation agreement almost one year earlier. His argument that concealment of the fact of her pregnancy would be a ground to set aside the marital settlement agreement is without merit.
