In an action to recover damages for goods sold and delivered, plaintiff appeals from an order of the Supreme Court, Westchester County (Burchell, J.), entered May 27, 1983, which granted the motion of defendant Joseph Fiegoli to vacate a default judgment entered in the action. Order reversed, on the law and the facts, with costs, motion denied and default judgment reinstated. Defendant Joseph Fiegoli moved to vacate a default judgment of an ground that he had not been personally served with a summons in the action, as asserted in an affidavit of service executed by plaintiffs process server. We conclude that plaintiff introduced sufficient evidence at the traverse hearing to sustain its burden of proving that it had obtained personal jurisdiction over Fiegoli by causing the summons to be served upon him at his residence (see Smid v Lombard, 83 A.D.2d 877). Plaintiffs process server unequivocally testified that he had, indeed, personally served the summons upon Fiegoli on September 15, 1979, after refreshing his recollection by referring to the affidavit of service he executed in accordance with the requirements of CPLR 306 and the log in which he recorded the name and address of each party upon whom he served legal papers and the date of such service. Special Term, however, credited the testimony of Fiegoli that he was out of the State on the day that the summons was allegedly served upon him, which testimony was based on notations in his personal diary. We credit the testimony of plaintiffs process server, who refreshed his recollection with more reliable contemporaneous records concerning his service of the summons. Moreover, Fiegolis assertion that he neither received the summons at issue nor any correspondence relating to the default judgment appears highly questionable, given his admission at the hearing that he had received two registered letters concerning this matter sent by plaintiffs counsel in April and June of 1979 to the same address recorded in the process servers affidavit of service. Fiegoli also acknowledged, on cross-examination, that he had retained counsel to contact plaintiff on his behalf after receiving the above-registered letters. The record is, thus, replete with evidence that Fiegoli was fully aware of the outstanding obligations due to plaintiff for a period of more than two years prior to the entry of the default judgment on December 3, 1979 and that he defaulted in appearing. Fiegoli has failed to establish a valid excuse for his default and for his delay of over two years in moving to vacate the default judgment (see Lincoln First Bank-Cent. v Bombard Chevrolet, 55 A.D.2d 1048).
