Key legal question
Whether the office's order setting a 20-day period under Art. 108 LP was null rather than merely voidable.
Extracted holding
The order was not null; it was, at most, challengeable by timely complaint.
Extracted reasoning
A choice among the claim procedures under Arts. 106–108 LP is not void absent a manifestly untenable violation of mandatory public-interest rules. The office had to apply the claim procedure because the mortgage creditor's assertion excluded the rents from seizure; the debtor and creditor had to litigate the claim within the statutory time limit.
