Unwed parents in Singapore are adopting their own biological children to formalise their legal status and gain access to benefits such as public housing, tax reliefs and inheritance rights, a process that mothers describe as lengthy, costly and emotionally draining.
Finance executive Ms Lim, 35, who declined to give her full name, began the adoption process when her daughter was around 18 months old. The process took a year and a half and cost S$6,000 in legal and administrative fees. She said she was surprised to learn that children born out of wedlock are viewed as “illegitimate” under Singapore law, meaning she could not buy an HDB flat with her baby as they would not be recognised as a family nucleus, and her child would not be eligible for the Baby Bonus cash gift of S$11,000 among other government initiatives.
“I was surprised because it sounds rather strange. I gave birth to her, but I actually have to adopt her, and her status will be an adopted child,” said Ms Lim. She described the process as “very unfair”.
In a 2025 written reply to a parliamentary question by Workers’ Party MP Fadli Fawzi, Social and Family Development Minister Masagos Zulkifli said there were an average of about 745 non-marital births a year to Singapore citizen mothers from 2020 to 2024. Of those, 12 children were successfully adopted by their biological parents within the same period.
Family lawyers explained that a biological parent does not cease to be a child’s legal parent simply because the child was born outside marriage, but the child’s legal status differs. Associate director of the Family Law and Probate Department at PKWA Law Practice Derek Choo said: “What changes with adoption is the child's legal status, not the relationship itself.”
Unwed mothers told CNA that inheritance was a key driver. If an unmarried parent dies without making a will, the illegitimate child has no automatic right to inherit his or her estate in Singapore if there are other surviving family members. Ms Jaspreet Kaur, director of private wealth and family practice at Yuen Law, said that while the mother can bypass this by writing a clear will, “the child still loses out on automatic statutory protection”.
Ms Moon, 36, a finance executive who began the adoption process in 2018, said: “The fact that I'm the biological mother and my daughter may not automatically inherit from me if anything were to happen to me was pretty alarming.” She also pursued adoption to formally sever ties with her daughter’s biological father, who has been absent since the child's birth. Family lawyer Ms Kaur said failing to adopt leaves the door open for the biological father to interfere legally, including requesting custody and access.
When it comes to housing, unwed parents and their children are not recognised as a family nucleus under HDB rules, meaning they are not eligible for family-tier Build-to-Order flats, family housing grants, priority balloting schemes or subsidised interim rental programmes such as the Parenthood Provisional Housing Scheme. They must wait until age 35 to buy a home as a single applicant, though they may appeal to HDB on a case-by-case basis.
In response to queries from CNA, a spokesperson for the Ministry of Social and Family Development (MSF) said government benefits that support a child’s growth and development are available to Singapore citizen children regardless of their parents' marital status. The spokesperson added that unwed parents do not need to adopt their biological children to qualify for government benefits that are extended regardless of parental marital status. “Where certain benefits or laws differentiate based on marital status, these reflect the government's longstanding policy of supporting parenthood within marriage,” the spokesperson said.
Ms Christina Anthony, 42, said she considered adoption to safeguard her son’s inheritance but decided not to proceed as the process could cost around S$5,000 to S$7,000, which was a major financial burden for her.
