An Indian man has been sentenced to three months and three weeks in jail in Singapore after being convicted of bigamy, a serious criminal offence in the country. The case has drawn attention not only because of the deceit involved, but also due to the impact on both women caught in the deception.
Indian Man Behind the Case
The accused, 49-year-old Vaithialingam Muthukumar, had been married to his first wife, a Singaporean citizen aged 55, since 2007. Their marriage, solemnised in India, was legally binding and recognized in Singapore. In 2011, Muthukumar moved to Singapore to join his wife.

However, beneath the facade of his settled married life, he began an extramarital relationship with a colleague. That relationship eventually culminated in a second secret marriage—one that would ultimately expose his double life and land him in jail.
Affair Turns Into Marriage
Muthukumar’s colleague, identified as 43-year-old Singaporean woman, Salmah Bee Abdul Razak, entered into a romantic relationship with him despite knowing he was married. Reports revealed that Muthukumar convinced her to marry him, claiming he wanted a child and assuring her that he would divorce his first wife after their marriage.
Yielding to his insistence, Salmah agreed. In August 2022, the pair travelled to Nagore, India, where they entered into a Muslim marriage officiated by a religious leader. This marriage, however, remained valid and was never dissolved—while his first marriage was still intact.
A Child Exposes the Secret
For months, Muthukumar continued living with his first wife in Singapore while secretly maintaining his relationship with Salmah. The situation reached a turning point in September 2023, when Salmah gave birth to a baby boy, fathered by Muthukumar.
The secret unraveled in a dramatic way. On the day of the delivery, Muthukumar’s first wife—who worked in the hospital—saw him emerging from the delivery suite, a section restricted to authorized personnel. Suspicious of his presence there, she confronted him. It was then that Muthukumar confessed about his second marriage and his child with Salmah.
Deception on Multiple Fronts
The betrayal did not end with his first wife’s discovery. Just months later, Muthukumar attempted to secure permanent resident status in Singapore by applying as the spouse of a Singapore citizen—referring to his second wife, Salmah.
On June 12, 2024, he submitted legal forms declaring that he had no other marriages, despite still being married to his first wife. The deliberate omission amounted to a false declaration. His deception might have continued had Salmah herself not disclosed the truth.
In July 2024, Salmah informed the Ministry of Manpower that Muthukumar was married to both her and another woman. Following this revelation, his PR application was rejected in October, and legal proceedings began.
Court Proceedings
During the trial, Muthukumar pleaded guilty to one charge of conspiring to commit bigamy with his second wife and another for making a false declaration in official documents.
The Deputy Public Prosecutor (DPP) argued that Muthukumar’s actions were calculated and deceitful. The court heard that he had deliberately misled both women—keeping his first wife completely in the dark about his second marriage while misleading Salmah into believing he would leave his first wife.
The prosecution stressed that his actions were not a momentary lapse but a sustained pattern of deceit.
After reviewing the evidence, the court sentenced Muthukumar to three months and three weeks in jail. The judge underscored that bigamy remains a punishable offence in Singapore, reflecting the country’s strict stance on the sanctity of marriage and family integrity.

The conviction also highlighted the misuse of legal processes, as Muthukumar had attempted to exploit Singapore’s immigration system through false declarations. His case, authorities noted, serves as a reminder that dishonesty in personal and legal matters carries serious consequences.
The Impact on Both Women
The case has left both of Muthukumar’s wives devastated. His first wife endured the shock of discovering not only her husband’s infidelity but also his second marriage and child. For Salmah, the betrayal was different—she had knowingly entered a relationship with a married man but had been misled by promises of divorce and a future together.

The DPP argued that Muthukumar had effectively “deceived both wives,” as his first spouse was denied the truth about his double life, while his second wife was given assurances he never intended to honor.
Bigamy in Singapore
Under Singapore law, bigamy is a criminal offence punishable by imprisonment and fines. While the offence is rare, the case underscores the legal system’s commitment to upholding marital laws and protecting individuals from exploitation within relationships.
Experts note that Singapore’s firm stance helps deter fraudulent marriages, sham unions, and misuse of legal provisions, particularly in cases tied to residency and citizenship applications.
Wider Implications
This case has sparked discussions about trust, relationships, and the legal implications of dishonesty in marriage. Community members and legal experts have emphasized the need for vigilance when it comes to protecting the institution of marriage and preventing exploitation.
For Muthukumar, what began as an affair with promises of a “new life” for his second partner has ended in disgrace, prison time, and broken trust with both women. His conviction stands as a cautionary tale of how deceit can unravel not only personal relationships but also legal standing in a country where honesty and integrity are strictly enforced.
The sentencing of Vaithialingam Muthukumar marks yet another instance where personal deception collides with the law. His attempt to juggle two marriages, mislead authorities, and exploit the system backfired, costing him his freedom and reputation.
While his prison term may eventually end, the damage caused to his family, his partners, and his own credibility will linger much longer—a stark reminder that truth in relationships, as in law, is not optional but fundamental.
