XZE v XZF

Facts

XZE (the Mother) and XZF (the Father) married on 24 November 2011 and have a son, aged 13. The family lived in Australia for most of the marriage until the Mother moved to Singapore with the child in early 2024. Divorce proceedings (Divorce No 3679 of 2024) began on 13 August 2024 and interim judgment was granted on 17 February 2025. The parties agreed all ancillary matters except maintenance, which depends on whether the child attends a private or a government special needs school.

It was not disputed that the child has Autism Spectrum Disorder and Attention Deficit Hyperactivity Disorder with mild intellectual disability, and both parents agreed he needs a special needs school. The Mother put in a report by Dr Jared Ng without leave; when the Father sought to expunge it, she applied for leave under Rule 35(4) of the Family Justice Rules 2014 to adduce it and a second report by Dr Tian Cheong Sing. The Assistant Registrar dismissed her application, and she appealed (Registrar's Appeal No 3 of 2026) to District Judge Kenneth Yap.

Issues

1. What threshold an applicant must meet for leave under Rule 35(4) to adduce a medical report on a child.
2. Whether the two medical reports should be admitted on the question of private versus government special needs schooling.

Holding

The court dismissed the Mother's appeal, refusing leave to adduce both medical reports. Costs were fixed at $1,200 (all-in), payable by the Mother.

Reasoning

The judge held that leave under Rule 35(4) turns on necessity, not relevance alone. Rule 35 aims to protect children from unnecessary assessment, so the purpose of the expert evidence and the questions it would answer must be clear. Drawing on XAB v XAC [2024] SGFC 53, the judge framed the relevant factors as cogency, fairness, the child's best interests, cost and delay, and the impact on a therapeutic outcome.

On cogency, neither report addressed the disputed issue; neither doctor was asked whether a private or a government-run school suited the child better, and the judge doubted that such a comparison fell within medical expertise. On fairness, the Father's lack of input was not fatal, as the issue was the child's educational needs. But the Father, who disagreed with both doctors, would likely seek his own expert, and given that the child had resisted assessment, repeated assessments might not serve his welfare. The choice of school was in the end a question of affordability, and the Mother could set out the differences between options in her own affidavit, so a tit-for-tat exchange of expert opinion was not worth the cost and delay. Nor would it help the parents, who must co-parent for years, and the Father had in any case seen the reports. Costs followed the event to instil discipline in the appellate process, although the appeal was motivated by the child's welfare.
