Conversion raises two quite different questions which students routinely run together. The first is a question of status: has the person become a Muslim? The second is a question of consequence: what happens to the legal relationships that person was already in? Indian law answers the first generously and the second restrictively. A genuine profession of faith makes a person a Muslim, but it does not release that person from obligations already incurred under another personal law.
Legal Framework
| Provision or rule | Reference | Effect |
|---|---|---|
| Profession of faith | Classical Muslim law | A person of full age and sound mind becomes a Muslim by professing belief in the unity of God and the prophethood of Muhammad; no particular ceremony is essential |
| S.2 | Muslim Personal Law (Shariat) Application Act, 1937 | Once a Muslim, the person is governed by Muslim personal law in the enumerated matters |
| S.4 | Dissolution of Muslim Marriages Act, 1939 | Renunciation of Islam by a married Muslim woman, or her conversion to another faith, does not by itself dissolve her marriage |
| S.13(1)(ii) | Hindu Marriage Act, 1955 | Conversion of a spouse to another religion is a ground of divorce available to the other spouse, not an automatic dissolution |
| Caste Disabilities Removal Act, 1850 | A person does not forfeit rights of property or inheritance by reason of renouncing or being excluded from a religion |
How Conversion Takes Place
There is no prescribed form. A person of full age and sound mind who professes Islam becomes a Muslim. In practice conversion is evidenced by a declaration before a mosque committee or other competent religious authority, and a certificate is issued; but the certificate is evidence of the conversion, not the source of it. A minor cannot ordinarily convert of his own volition.
Why the absence of formality creates the difficulty: Because the threshold for acquiring Muslim status is so low, and because Muslim personal law permits a man up to four wives, conversion became an obvious route for a man married monogamously under another personal law who wished to take a second wife. The law's response could not sensibly be to make conversion harder, since that would trespass on freedom of religion under Art.25. It was instead to sever the link between change of religion and dissolution of the existing marriage. That is the whole doctrinal move made in Sarla Mudgal and confirmed in Lily Thomas.
Conversion Does Not Dissolve a Subsisting Marriage
This is the central proposition of the topic.
Facts: The petitions concerned Hindu husbands who, being already married under Hindu law, converted to Islam and then contracted second marriages, relying on the Muslim law permission of polygamy, without obtaining any divorce from their first wives.
Issue: Whether a Hindu husband who converts to Islam can contract a valid second marriage during the subsistence of his first Hindu marriage, and whether he is liable for bigamy.
Held: The second marriage was held invalid. A marriage solemnised under the Hindu Marriage Act 1955 can be dissolved only on a ground recognised by that Act and by a decree of a competent court. Conversion to another religion is not such a ground of automatic dissolution; under S.13(1)(ii) it gives the other spouse a ground for divorce, which is a very different thing. The first marriage therefore continued to subsist, and the second marriage, contracted during its subsistence, was void and rendered the husband liable for bigamy. The Court also urged the enactment of a uniform civil code under Art.44.
Relevance: The leading authority. The reasoning is important: the Court did not hold the conversion ineffective. It held that the first marriage, having been contracted under a statute, could be dissolved only in the manner that statute allows.
Facts: A review of, and a further challenge arising out of, the position taken in Sarla Mudgal. Hindu husbands who had converted to Islam and remarried contended that Sarla Mudgal infringed their freedom of religion under Art.25 and that they could not be prosecuted for bigamy.
Issue: Whether the Sarla Mudgal principle was correct, and whether its application violated Art.25.
Held: Sarla Mudgal was affirmed. Conversion does not automatically dissolve a subsisting marriage. A second marriage during the subsistence of the first exposes the convert to liability for bigamy. Art.25 protects freedom of conscience and the free profession, practice and propagation of religion; it does not confer a right to escape the legal obligations of a marriage validly contracted under another law, and a prosecution for bigamy does not interfere with religious freedom.
Relevance: Confirms and settles Sarla Mudgal, and disposes of the Art.25 argument. Cite both cases together; Sarla Mudgal establishes the principle and Lily Thomas answers the constitutional objection to it.
Why the two cases are the pair to cite: Sarla Mudgal decides the personal law point. Lily Thomas decides the constitutional point. A question on conversion almost always needs both, because the argument a convert will run is the Art.25 argument, and that is answered only by Lily Thomas.
Older textbooks cite Skinner v Orde (1871) 14 Moore's Indian Appeals 309 as authority on the effect of conversion to Islam for the purpose of a second marriage. The Bombay High Court in Muncherji Cursetji Khambata v Jessie Grant Khambata records that in Skinner v Orde the question was discussed but not decided. Do not rely on it as authority for a proposition it did not decide.
Note also that there are two different Privy Council decisions reported under the name Skinner v Orde, one at 14 Moore's Indian Appeals 309 concerning Muslim law and one at (1879) 6 Indian Appeals 126 concerning pauper appeals and procedure. Indian courts cite both under the same name. The modern authorities for the proposition are Sarla Mudgal and Lily Thomas.
Effects of Conversion, Set Out by Head
| Head | Effect of conversion to Islam |
|---|---|
| Personal law applicable | The convert becomes governed by Muslim personal law in the matters enumerated in S.2 of the 1937 Act, prospectively |
| Subsisting marriage | Not dissolved. It continues to be governed by the law under which it was solemnised, and can be dissolved only in the manner that law allows: Sarla Mudgal, Lily Thomas |
| Second marriage after conversion | Void if the first marriage subsists, and the convert is liable for bigamy |
| Capacity to marry afresh | Available only once the earlier marriage has been lawfully dissolved by decree |
| Rights of property already vested | Not divested. The Caste Disabilities Removal Act 1850 protects a person from forfeiture of property or inheritance rights by reason of change of religion |
| Succession to the convert's estate | Governed by Muslim law of inheritance after conversion, subject to the point below on the convert's non Muslim relations |
| Guardianship and custody | The welfare of the minor remains the paramount consideration; conversion is a relevant circumstance but not decisive |
| Maintenance of the first wife | Continues. The wife of the subsisting marriage retains her rights, and the criminal maintenance provision applies irrespective of religion |
Why vested property rights survive conversion: Under classical law apostasy carried severe civil consequences, including exclusion from inheritance. The Caste Disabilities Removal Act 1850 was enacted to remove exactly that disability, and it operates in both directions: a person who leaves a religion does not forfeit rights of property or inheritance on that account. This is a small but frequently examined point, because it is counter intuitive against the classical background.
Conversion by a Married Muslim Woman: S.4 of the 1939 Act
The reverse case is dealt with by statute. Under classical Hanafi law as administered in India, apostasy by a wife dissolved her marriage automatically, and Muslim wives with no available ground of dissolution began renouncing Islam in order to escape unhappy marriages.
S.4 of the Dissolution of Muslim Marriages Act 1939 closed that route. Renunciation of Islam by a married Muslim woman, or her conversion to another faith, does not by itself dissolve her marriage. She must instead proceed on one of the grounds in S.2 of that Act.
Why S.4 and the Sarla Mudgal line point the same way: Both remove conversion as a self help mechanism for exiting a marriage. S.4 does it by statute for the Muslim wife; Sarla Mudgal and Lily Thomas do it by decision for the convert to Islam. The unifying principle is that a marriage is dissolved by the law that created it, through the procedure that law prescribes, and not by a unilateral change of religious allegiance. Making that connection explicitly is what turns a list of rules into an argument.
Illustrations
-
Second marriage after conversion. A Hindu husband married under the Hindu Marriage Act 1955 converts to Islam and marries a second wife without any divorce. The first marriage subsists, the second marriage is void, and he is liable for bigamy: Sarla Mudgal, Lily Thomas. His conversion is effective as to his religion and future personal law, but achieves nothing as to the first marriage.
-
The wife's remedy. On the same facts, the first wife is not left to the criminal law alone. Her husband's conversion is a ground on which she may seek divorce under S.13(1)(ii) of the Hindu Marriage Act 1955, and she retains her right to maintenance.
-
Muslim wife renouncing Islam. A Muslim wife, unable to establish any ground under S.2 of the 1939 Act, renounces Islam intending to bring the marriage to an end. By S.4 the marriage is not dissolved. She must establish a S.2 ground, for example cruelty under S.2(viii) or failure to maintain for two years under S.2(ii).
-
Property not forfeited. A Hindu converts to Islam. His right to a share in property that had already vested in him is not lost by reason of the conversion, the Caste Disabilities Removal Act 1850 having abolished that disability.
-
Conversion and the validity of the marriage itself. A Muslim man marries a Hindu woman who does not convert. The marriage is not void but irregular (fasid) under Sunni law, it subsists until terminated, and the child is legitimate and inherits from the father: Mohd Salim v Shamsudeen (2019). Contrast the position under Shia law, which has no fasid category, so the marriage would be void.

Key Cases
Sarla Mudgal v Union of India (1995) Sarla Mudgal v Union of India 1995
Issue: Whether a Hindu husband converting to Islam may contract a valid second marriage while his first Hindu marriage subsists.
Rule: A marriage solemnised under the Hindu Marriage Act 1955 is dissolved only on a ground recognised by that Act and by decree. Conversion is not a mode of automatic dissolution; it merely gives the other spouse a ground of divorce under S.13(1)(ii).
Held: The second marriage was invalid and the husband liable for bigamy. The Court urged enactment of a uniform civil code.
Lily Thomas v Union of India (2000) Lily Thomas v Union of India 2000
Issue: Whether the Sarla Mudgal principle is correct and whether it violates Art.25.
Rule: Conversion does not dissolve a subsisting marriage, and Art.25 confers no right to escape obligations validly incurred under another personal law.
Held: Sarla Mudgal affirmed. Liability for bigamy upheld; no infringement of religious freedom.
Mohammed Salim v Shamsudeen (2019) Mohd Salim v Shamsudeen 2019
Issue: Whether the marriage of a Muslim man and a Hindu woman who has not converted is void or irregular.
Rule: Such a marriage is irregular (fasid) under Sunni law and subsists until terminated.
Held: The child is legitimate and entitled to a share in the father's property; the wife takes dower but does not inherit.
Distinctions
| Basis | Conversion under classical law | Conversion under Indian law today |
|---|---|---|
| Effect of apostasy by a wife | Dissolved the marriage automatically | Does not dissolve it: S.4, Dissolution of Muslim Marriages Act 1939 |
| Effect on rights of property | Forfeiture of inheritance | No forfeiture: Caste Disabilities Removal Act 1850 |
| Effect of conversion to Islam on an earlier marriage | Argued to dissolve it and permit remarriage | Does not dissolve it: Sarla Mudgal, Lily Thomas |
| Basis | Automatic dissolution | Ground of divorce |
|---|---|---|
| Meaning | The marriage ends by operation of law on the event occurring | The event entitles a spouse to apply for a decree |
| Who controls the outcome | Neither party; it simply happens | The innocent spouse, who may or may not sue |
| Conversion of a spouse | Not an automatic dissolution | Is a ground, under S.13(1)(ii) of the Hindu Marriage Act 1955 |
| Practical significance | Would allow the convert to remarry at once | Leaves the first marriage subsisting until decree, so remarriage is bigamy |
Flashcards
What is required for a valid conversion to Islam?
A profession of the faith by a person of full age and sound mind, believing in the unity of God and the prophethood of Muhammad. No particular ceremony is essential.
Does conversion to Islam dissolve a marriage solemnised under the Hindu Marriage Act 1955?
No. The marriage subsists and can be dissolved only on a ground recognised by that Act and by decree: Sarla Mudgal (1995), Lily Thomas (2000).
What is the status of a second marriage contracted after conversion while the first subsists?
Void, and the convert is liable for prosecution for bigamy.
What answer did the Supreme Court give to the argument that prosecuting a convert for bigamy violates Art.25?
In Lily Thomas it held that Art.25 protects freedom of religion but confers no right to escape legal obligations validly incurred under another personal law.
What remedy does the first wife have when her husband converts and remarries?
She may seek divorce on the ground of the husband's conversion under S.13(1)(ii) of the Hindu Marriage Act 1955, and she retains her right to maintenance, including under the criminal maintenance provision.
What does S.4 of the Dissolution of Muslim Marriages Act 1939 provide?
That renunciation of Islam by a married Muslim woman, or her conversion to another faith, does not by itself dissolve her marriage.
Why was S.4 of the 1939 Act enacted?
Because classical Hanafi law as administered in India dissolved the marriage on the wife's apostasy, and Muslim wives with no available ground of dissolution were renouncing Islam to escape unhappy marriages.
Does a convert forfeit property rights already vested in him?
No. The Caste Disabilities Removal Act 1850 abolished forfeiture of property or inheritance rights by reason of change of religion.
Can Skinner v Orde be cited for the effect of conversion on an earlier marriage?
No. The question was discussed but not decided in that case. The authorities are Sarla Mudgal and Lily Thomas.
Exam Scenario
Problem: Vikram and Meena married in 2012 under the Hindu Marriage Act 1955. In 2020, after the marriage broke down but without any divorce proceedings, Vikram converted to Islam, took the name Vahid, and in 2021 married Salma under Muslim rites. Salma was aware of the first marriage. A child was born to Salma in 2022. Vikram died intestate in 2026 leaving property, and leaving Meena, Salma, and the child. Meena prosecutes for bigamy and claims the whole estate; Salma claims a widow's share and claims that the child is legitimate. Advise.
Step 1: Status of the conversion
Vikram's conversion was effective to make him a Muslim, and from 2020 he was governed by Muslim personal law in the matters enumerated in S.2 of the 1937 Act.
Step 2: The first marriage
Apply Sarla Mudgal and Lily Thomas. The 2012 marriage was solemnised under the Hindu Marriage Act 1955 and could be dissolved only on a ground under that Act, by a decree of a competent court.
Conversion is not automatic dissolution. Under S.13(1)(ii) it gave Meena a ground of divorce, which she did not exercise. The 2012 marriage therefore subsisted until Vikram's death, and Meena is his widow.
Step 3: The second marriage and bigamy
Because the first marriage subsisted, the 2021 marriage to Salma was contracted during its subsistence and is void. Vikram was liable for bigamy in his lifetime, but the prosecution abates on his death, so the finding now matters for status and succession rather than punishment.
Address the Art.25 defence expressly and reject it on Lily Thomas. Salma's knowledge of the first marriage does not validate the second, though it may bear on any claim she makes in equity.
Step 4: Salma's claim to a widow's share
The 2021 marriage being void, Salma is not a widow and cannot take a widow's share in the estate.
| Defect | Category | Consequence |
|---|---|---|
| Difference of religion, as in Mohd Salim v Shamsudeen (2019) | Irregular, fasid | The marriage subsists until terminated |
| A subsisting prior marriage, as here | Void, batil | No marriage at all, so no widow's share |
The Mohd Salim route is therefore not open to Salma.
Step 5: The child's legitimacy, reasoned rather than asserted
- The 2021 marriage being void, the child is prima facie illegitimate, and under Muslim law an illegitimate child does not inherit from the father.
- Consider whether acknowledgment of paternity can assist: Muhammad Allahdad Khan v Muhammad Ismail (1888), Habibur Rahman Chowdhury v Altaf Ali Chowdhury (1921). Acknowledgment raises a presumption of a lawful marriage where the marriage is merely unproved.
- It cannot legitimise a child where the marriage is disproved or was legally impossible. Here the marriage is proved, and proved to be void, so acknowledgment cannot cure the position.
The child cannot inherit from Vikram under Muslim law, which is a recognised hardship of the doctrine.
Step 6: Succession
Vikram died a Muslim, so his estate devolves under Muslim law of inheritance, and Meena, as his lawful widow, takes a widow's share.
Add the Caste Disabilities Removal Act 1850 point: Meena's rights are not affected by the difference of religion between her and her husband at the date of death.
Do not begin by doubting the conversion. The law does not invalidate it; only the consequences Vikram sought fail.
Distinguish the fasid line carefully. The defect here is a subsisting prior marriage, which is batil, not the difference of religion that made the marriage in Mohd Salim merely irregular.
Meena does not take the whole estate as she claims. The shares of the other heirs must be worked out.
Conclusion. Vikram's conversion changed his personal law prospectively but achieved none of the consequences he sought, and the burden of that failure falls hardest on Salma and the child rather than on him.
