49-year-old sentenced after secret marriage and false declarations uncovered in Singapore
A Singapore workplace drama turned into a courtroom case when a man was caught visiting his second wife at the hospital where his first wife worked. The discovery led to charges of bigamy and false declarations, resulting in a jail sentence.
Secret Marriage and Double Life
Indian national Vaithialingam Muthukumar, 49, married his first wife, a Singaporean woman now aged 55, in India in 2007. He later moved to Singapore in 2011 and began working here. At work, he met Salmah Bee Abdul Razak, a 43-year-old colleague, and started a romantic relationship with her despite already being married.
In August 2022, Vaithialingam and Salmah entered into a Muslim marriage in Nagore, India. Both were aware that his first marriage remained valid and that his wife was alive, making the second marriage unlawful under Singapore law.
The Hospital Encounter
On September 14, 2023, Salmah gave birth to a son at KK Women’s and Children’s Hospital. Vaithialingam went to visit her in the delivery suite, unaware that his first wife worked at the same hospital. She spotted him exiting the restricted ward and confronted him. This chance encounter exposed the secret marriage.
False Declarations to Authorities
In June 2024, Vaithialingam submitted a permanent residence application to the Immigration and Checkpoints Authority (ICA), with his first wife acting as sponsor. He falsely declared that he did not have any other marriages, including customary ones. The application was rejected in October 2024.
Investigations revealed that Vaithialingam had also made false statements in previous applications for his visit pass. His second wife later reported the bigamy to the Ministry of Manpower, leading the case to be referred to ICA and subsequently the police.
Court Proceedings and Sentencing
During trial, prosecutors argued that Vaithialingam had deceived both women. His first wife discovered the affair by “pure chance” at the hospital, while his second wife was misled by promises of divorce. The prosecution noted that the offence lasted over a year before being uncovered.
On August 21, 2025, Vaithialingam pleaded guilty to conspiring to commit bigamy and making false declarations. He was sentenced to three months and three weeks’ jail. A third charge was taken into consideration during sentencing.
Broader Legal Context
Under Singapore law, bigamy is punishable with up to seven years in jail and a fine of up to S$10,000 (US$7,760). The case underscores strict enforcement of marriage laws and immigration regulations, sending a warning about the consequences of deception in personal and legal matters.
The unusual case of Vaithialingam Muthukumar highlights how deception in personal relationships can spill into legal and immigration violations. His arrest and conviction serve as a reminder that Singapore’s laws on bigamy and false declarations are rigorously enforced, protecting both family institutions and the integrity of public systems.
