Key legal question
Whether the daughter still occupied the claimant's apartment under Art. 16c OPC-AVS/AI for housing-cost allocation.
Extracted holding
The daughter did not occupy the apartment during the disputed period; the claimant lived there alone.
Extracted reasoning
Art. 16c OPC-AVS/AI turns on actual co-occupancy, not formal registration or tax domicile. The insured's uncontested statement that the daughter left in September 2008 was sufficient and the contrary official indications could be rebutted.
