Reg. dasti notice

Dear Ld. Experts,

In civil matter, Dasti notice issue to a party given his office address, if the dasti notice handed over to the HR of the office by the court's person instead of the party (because the person whoes dasti is issue to was on leave that day).

in this case will this dasti notice will be considered as 'Served'? or else if the court person produced affidavit that notice handed over to HR of the office-will that be considered by court as Notice Served?

Thanks!
