Key legal question
Whether the claim was forfeited because the collocation plan was not challenged in time.
Extracted holding
The claim was forfeited; the collocation plan became final against the claimant when the statutory challenge period expired unused.
Extracted reasoning
A creditor who had already submitted the claim in the succession notice was treated as a bankruptcy creditor and was given the same opportunity to challenge the refusal. Failure to use that remedy made the plan binding.
