अप्रतिविहिताः सुखावस्था बिभृयुः परं चत्वारि वर्षाण्यष्टौ वा ज्ञातयः ॥ कZ_०३.४.२६ ॥
aprativihitāḥ sukhāvasthā bibhṛyuḥ paraṃ catvāri varṣāṇy aṣṭau vā jñātayaḥ
When no provision/notice has been made (aprativihita), the wife should be maintained in reasonable comfort (sukhāvasthā). Her kinsmen (jñātayaḥ) should support her—at most for four years, or for eight years (in extended cases).
It shifts interim support to the kin network (jñātayaḥ) with a defined maximum duration, while prescribing a minimum standard of living for the wife.
