In In re Marriage of Morse, 143 Ill. App. 3d 849, 493 N.E.2d 1088, 98 Ill. Dec. 67 (1986), the court noted that the respondent's motion to supplement the record with affidavits of trial counsel and his secretary, who had signed the proof of service, was denied. Morse, 143 Ill. App. 3d at 852. However, the court noted that at the hearing on a motion to strike respondent's posttrial motion, the circuit court stated that "it had no reason to suspect that respondent's attorney would post-date the proof of service." Morse, 143 Ill. App. 3d at 852. The appellate court relied upon the circuit court's statement in concluding that the "proof of service date was sufficiently analogous to an affidavit attesting to the mailing date so as to extend the reasoning in Schulman" to that case. Morse, 143 Ill. App. 3d at 852.
