The Chapter 13 Trustee objected to a proof of claim as untimely filed because the creditor filed a proof of claim nearly five months after the deadline had passed.  The Court found that although the creditor was not included in the creditor mailing matrix, the creditor had actual knowledge of the Debtors' bankruptcy approximately a month before the claims filing period expired.  Therefore, the Court sustained the Trustee's objection, and disallowed the claim in its entirety.
