The statutory scheme governing intestate succession mandates equal and simultaneous devolution of property among all Class I heirs, leaving no legal basis for preferential claims by any sibling.

Self-acquired property devolves in equal shares upon the Class I heirs listed in the Schedule to the Act, including sons and daughters, in accordance with Section.

A father enjoys absolute testamentary freedom in respect of his self-acquired property, subject to the will being legally executed and free from fraud, coercion, or undue influence.

Self-acquired property of a living person cannot be forced into partition. Similarly, property gifted or willed exclusively to a single person cannot be partitioned among siblings.

Testamentary disposition is restricted to the testator’s undivided share in ancestral property. The coparcenary interests of other heirs cannot be defeated or diluted.

A daughter as a coparcener is legally entitled to seek partition of ancestral property during the father’s lifetime, subject to procedural compliance.
