For satisfaction from the highest bid, filing in the distribution proceeding is necessary. Section 210 EO governs deadline and content; section 209 EO provides the procedural framework of the distribution hearing. Section 216 EO orders the classes and the ranking.
For an association claim, additional evidence that the section 27 WEG requirements are met is needed. Without timely action and annotation the priority lien does not exist; the claim can then rely neither on the preferred rank nor on the linked assumption under section 27(3) WEG.
For the buyer the filing is economically important. If the arrears are correctly categorised and fully satisfied from the highest bid, the unit is economically free; if only partly satisfied, section 27(3) WEG applies to the remainder.
