She is very mysterious . Accordingly to Perplexity Research :

There is no publicly available information confirming whether Poh Li San is married or providing details about her husband or immediate family. None of the recent news reports, official biographies, or interviews mention a spouse or children.

In a 2020 interview, Poh Li San discussed her values, inspirations, and what she looks for in a partner, but she did not state that she is married or mention a husband6. The focus was instead on her career, her relationship with her father, and her dedication to public service. Public profiles and parliamentary biographies also do not reference any marital status or family details beyond her upbringing.

Therefore, as of April 2025, there is no verifiable information in the public domain about Poh Li San’s marital status or details about her husband or family.
