¶1Defendants have appealed from an order denying their petition to strike or open a default judgment entered against them in an action of assumpsit based on a contract they had entered into with plaintiff to construct a building for them.
¶2PETITION TO STRIKE
¶3The only reason alleged in the petition to strike is that of lis pendens, i. e. that at the time the assumpsit action was filed there was pending in the same court a mechanics lien claim between the same parties based on the same contract.
¶4PETITION TO OPEN
¶5Recognizing that the sheriff’s return of service of the complaint was regular on its face, the defendants, nevertheless, allege they had no notice of the action until they were advised by their attorney that judgment had been entered against them. They also allege that the plaintiff should have known the suit would be contested since the mechanics lien was being vigorously contested. Furthermore, they allege they have a full and complete defense to the action and a possible counter claim which they set forth in a proposed answer and counter claim attached to their petition.
¶6*52The petition to open would appear to have been timely filed
¶7We have held that although service of process may be good, nevertheless, a person may assert lack of knowledge of the suit for reasons other than improper service in seeking to have a default judgment opened. Campbell v. Heilman Homes, Inc., 233 Pa.Super. 366, 335 A.2d 371 (1975) cited in Maurice Goldstein Co. v. Margolin, 248 Pa. Super. 162, 374 A.2d 1369 (1977). For this reason the lower court was in error in deciding this issue solely on the basis that good service was admitted by defendants.
¶8Therefore we conclude that appellants are entitled to an opportunity to offer evidence of lack of knowledge of the suit in order to establish the reason for their failure to file an answer to the complaint within the period of time allowed for that purpose.
¶9Since the lower court decided this issue without the benefit of depositions or oral argument as provided for by Pa.R.C.P. 209, that part of the order refusing the petition to open this judgment is reversed and the case remanded for further proceedings.
¶10That part of the order denying the petition to strike the judgment is affirmed since no issues of fact were involved.
¶11. This mechanics lien claim was subsequently stricken by order of court.
¶12. The judgment was entered August 16, 1977. The petitions were filed August 25, 1977. The complaint had been served July 19, 1977.
