स्वयं आर्जितमविभाज्यमन्यत्र पितृद्रव्यादुत्थितेभ्यः ॥ कZ_०३.५.०३ ॥
svayaṃ ārjitam avibhājyam anyatra pitṛdravyād utthitebhyaḥ
Property acquired by oneself is not subject to division—except insofar as it has arisen from (or is traceable to) the father’s property.
It prevents heirs from re-labeling ancestral assets as ‘self-acquired’ and supports state-backed accounting in partition disputes.
