This is the most significant and least-discussed consequence of marriage under the Special Marriage Act, and it affects couples regardless of whether they are aware of it.
Section 21 of the Special Marriage Act provides that the property succession of persons married under the Act — and of the issue (children) of such marriages — is governed by the Indian Succession Act, 1925. Not by Hindu personal law. Not by Muslim personal law. Not by any community's personal law.
What this means practically: A Hindu who marries under the Special Marriage Act is no longer governed by the Hindu Succession Act, 1956 for property inheritance. The coparcenary structure — through which sons and daughters acquire rights in ancestral property by birth under Hindu law — is displaced. Inheritance from both spouses and from their children flows under the Indian Succession Act instead.
This does not affect the Section 28 divorce process directly. But it has real consequences for the settlement agreement in a mutual divorce. The property clause in the MoU should be drafted with awareness of which succession law actually governs — not assumed to reflect Hindu Succession Act coparcenary rules when they do not apply.
Practical advice: Couples with significant property or family inheritance interests should consult a property lawyer alongside the divorce process to understand the succession implications specific to their situation before finalising settlement terms.
