71 Pa. Stat. § 733-1002
Any depositor who disagrees with the amount shown by the books or other records of the institution to be due to him, shall present his claims to the secretary by presenting his deposit or pass books, or other evidence of indebtedness, to the secretary, within the time and in the manner designated by the secretary, pursuant to the provisions of this act. Any such depositor who shall not have received or shall have lost his deposit or pass book or other evidence of indebtedness, or who shall believe that the amount shown by such deposit or pass book or other evidence of indebtedness to be due to him is incorrect, shall, within the time designated by the secretary, present his claim to the secretary by whatever method he shall designate.
Any depositor who shall not present his claim within the designated time and in the manner provided by this section, shall be bound by the amount appearing to be due to him upon the books or records of the institution, or where the name of such depositor does not appear at all upon the books or records of the institution, or appears on such books or records but with no balance appearing to be due to him by the institution, shall be permanently barred from sharing in any distribution of the assets of the institution. However, the court may, upon petition and adequate cause shown, permit any depositor to file his claim upon a later date, but no claim shall in any event be allowed to be filed after the last day for the filing of exceptions to the first account of the secretary.
This section shall not, however, be construed to deprive any such depositor of any right of action at law or in equity which he may have against an employe or former employe of the institution, or upon the bond of such employe or former employe, for any act committed by such employe which resulted in such depositor's not appearing upon the books of the institution, or appearing upon them but being credited with an amount below that actually due.
The secretary shall prescribe the form for the proof of claim of all depositors and for the affidavit to be included therein. Whenever requested by any such depositor to prepare such proof of claim or to take the affidavit thereto, the secretary shall do so without any charge to such depositor.
