YCD v YCE

Facts

The applicant mother filed Originating Application (OAG) No 154 of 2025 under the Guardianship of Infants Act 1934 against the respondent, whom she alleged was the biological father of her daughter. She sought $8,926 in monthly maintenance or a lump sum of $1,071,120, an order that he undergo a paternity test, a declaration of paternity if the test established it, and an order that he bear the testing costs.

According to her, the two met through an introduction agency and had sexual relations; when she told him of the pregnancy he denied responsibility and cut off contact. She then married a former boyfriend, who agreed to be named as the father on the birth certificate although he was not the biological father. That marriage ended, and under a consent interim judgment of divorce the former husband was to maintain the child solely. The respondent accepted that he had sexual relations with her, though he said this was in the first quarter of the year rather than in August.

By Summons No 2950 of 2025, the respondent applied to strike out the whole application on the grounds that it disclosed no reasonable cause of action, that striking out was in the interests of justice, and that it was an abuse of process. The application was heard by an Assistant Registrar.

Issues

1. Whether the maintenance application disclosed a reasonable cause of action, including whether the court could order a paternity test
2. Whether the extended doctrine of res judicata or the rule against double recovery made the claim legally unsustainable
3. Whether the application was an abuse of the court's process

Holding

The Family Court dismissed the respondent's striking out application in SUM 2950, so the mother's maintenance and paternity application would proceed to a hearing. The applicant was awarded costs of $2,000, with disbursements of $150.

Reasoning

On cause of action, the threshold for striking out is high: the question is whether the pleadings, taken as true, show some chance of success. Doubts about the mother's timeline went to credibility, not to whether there was a question fit to be tried. Section 114 of the Evidence Act 1893 now creates only a rebuttable presumption of paternity, and no authority treats a birth certificate as conclusive, so with the admitted sexual relations there was a biological possibility of paternity. No provision or case expressly denied the court power to order a paternity test; WGM v WGN suggested it could use its inherent powers, and whether hardship justified doing so was itself a question for the hearing.

On res judicata, the court applied Henderson v Henderson, Nellie Goh and Andy Lim. The respondent was not a party to the uncontested divorce, had no privity of interest with the former husband, whose duty arose under a different provision of the Women's Charter, and could not have been bound by orders in those proceedings. The doctrine does not bar applications merely because they were not brought sooner, and whether there were good reasons for the timing needed evidence. On double recovery, nothing limits a child to one maintenance order; AJE v AJF showed a stepfather and biological father may both owe duties. Because maintenance depends on a parent's means, the rule may not fit, and whether any overlap goes to quantum or bars a second order was an open question.

On abuse of process, pre-action disclosure was aimed at identifying parties or tracing property and was not clearly applicable, gaps in evidence were for the merits, and the claim appeared at least possibly genuine on a point never litigated, so it was not vexatious or oppressive.
