द्रव्यमपुत्रस्य सोदर्या भ्रातरः सहजीविनो वा हरेयुः कन्याश्च ॥ कZ_०३.५.०९ ॥
dravyam aputrasya sodaryā bhrātaraḥ sahajīvino vā hareyuḥ kanyāś ca
The property of a man without sons shall be taken by his full brothers or his co-resident kinsmen; and (failing them/along with them as specified) the daughters as well.
Co-residence signals economic interdependence and contribution; the law uses it as an administrable proxy for legitimate claim.
