The government has tightened birth registration procedures nationwide as a police investigation widens into a scheme that enabled about 500 Chinese children to obtain Thai nationality with fraudulent documents.
Authorities are prioritising efforts to prevent corruption and exploitation of Thailand’s civil registration system, deputy government spokeswoman Lalida Persvivatana said on Saturday following a number of arrests in the “fake fathers” scandal.
The Ministry of Interior has ordered an urgent review of birth registration procedures at all 878 district offices nationwide. It said cases involving a foreign parent must now include an in-person appearance before registration officers to confirm parental identity.
The measure aims to prevent impersonation and the use of forged documents, while reducing opportunities for criminal networks to exploit Thai nationality to hold property, conduct business or launder money through Thai citizens, Ms Lalida said.
A number of arrests were made this week as police and the Department of Provincial Administration closed in on a network that included district officers and hospital staff, as well as Thai men paid to pose as fathers of Chinese women’s children.
The probe is part of a wider investigation into a network headed by Chen Yin Lai, a Chinese national arrested in April 2024 on suspicion of laundering more than 70 billion baht through Thailand.
Police found that Chen and his Chinese wife had three children with Thai nationality, raising questions about the registration process.
Investigators said the network recruited Thai men as “fake fathers” to acknowledge paternity, allowing Chinese children to obtain Thai nationality and related rights. (Story continues below)
Five hospitals implicated
Pol Gen Samran Nualma, a deputy national police chief, said that more than 500 foreign children may have been falsely registered as Thai nationals, with staff at five private hospitals in Bangkok allegedly involved in facilitating the process.
He said at least 62 people have been linked to the network.
Police so far have arrested 27 suspects — 12 women and 15 men — including suspected fake fathers, Chinese mothers and registration-related personnel. The suspects were detained at the Bang Yi Ruea police station in Thon Buri district of Bangkok before being taken to court.
Among those arrested were Sunee Satitmanotham, a birth registration officer at Samitivej Thonburi Hospital, and Siriporn Nidthim, a registrar at the Thon Buri district office. Both declined to comment while being fingerprinted on Friday.
Investigators are pursuing 26 additional suspects accused of acting as fake fathers. The inquiry will also examine possible involvement of other district office personnel and private hospital staff.
One suspect, taxi driver Ongart Chaikulab, admitted signing documents acknowledging two children but denied knowingly taking part in wrongdoing. He said he received 2,000 baht each time as compensation for time spent away from driving his taxi.
Another suspect, Viroj Phumchaya, admitted signing paternity documents for four children from two Chinese families. He said he understood the families wanted to raise the children in Thailand but claimed he was unaware of the wider consequences.
Nominee shareholder
Another “fake father” suspect is already facing charges of acting as a nominee shareholder in China Railway Number 10 (Thailand), the company that built the State Audit Office headquarters, which collapsed during the March 2025 earthquake, killing 95 people.
The suspects initially face charges of aiding and abetting state officials in the wrongful performance or omission of duties.
Police are awaiting DNA test results before deciding whether to seek further arrest warrants, including for Chen Yin Lai’s Chinese wife and a Thai man accused of falsely acknowledging paternity of her three children.
Investigators believe the results will provide key evidence as the case expands.
Wittoon Sirinukul, deputy director-general of the Department of Provincial Administration, said fraudulent registrations could allow foreign children to gain the full rights and privileges of Thai citizens, including access to education, healthcare, welfare benefits and property ownership.
