Thomas Domboka v Esnath Madhamu

The applicant and respondent were divorced on 7 March 2002, with custody of their two minor children (A, a 10-year-old girl, and R, a 6-year-old boy) awarded to the respondent mother with reasonable access to the applicant father. In May 2002, the respondent left Zimbabwe for the United Kingdom and placed the children in the custody of her mother (the children's grandmother). She remained in the UK with no indication of returning to Zimbabwe or taking the children to the UK. On 30 October 2003, the applicant applied for variation of custody, alleging that: (1) the respondent had abandoned the children; (2) he had been denied access by the grandmother; and (3) the children's living conditions had deteriorated, affecting A's school performance. The respondent's legal practitioner filed an opposing affidavit on her behalf, as she was in the UK, but the respondent never filed her own affidavit despite initial indications that she would do so.

• Whether the respondent had abandoned custody of the minor children by leaving them with their grandmother while residing in the United Kingdom
• Whether a custodian parent's surrender of physical custody to a third party automatically entitles the non-custodian parent to custody
• What test must be applied when considering an application for variation of custody based on changed circumstances
• Whether the applicant discharged the onus of proving it was in the best interests of the children that custody be varied in his favour

The application for variation of custody was dismissed with no order as to costs.

In applications for variation of custody based on changed circumstances, the non-custodian parent bears a two-pronged onus: (1) to demonstrate that it is not in the best interests of the children to remain in the custody of the custodian parent; and (2) to prove affirmatively that it is in the best interests of the children that custody be awarded to the applicant. The best interests of the children remain paramount throughout. A custodian parent's surrender of physical custody to a third party does not automatically entitle the non-custodian parent to custody; the court must be satisfied with comprehensive evidence about the proposed custodial arrangements, including the applicant's financial position, domestic circumstances, and plans for the children's education and welfare.

Makarau J made important observations about the need for law reform in custody matters, noting that "courts in this jurisdiction remain with the unenviable and blindfold task of determining the interests of parties who are not before it. The minor children have no voice before this court yet it is their welfare that is being discussed and determined." The judge expressed hope that "the need to do justice to minor children will move for reform in this area of the law." The court also commented on the inadequacy of the opposing affidavit deposed to by a legal practitioner rather than the party herself, noting that with modern communication technology, there was no excuse for the respondent not to have filed her own affidavit. The judge observed that the adversarial nature of custody disputes often results in parents focusing on attacking each other rather than demonstrating how they can best serve the children's interests.

This case is significant in Zimbabwean family law for articulating the two-pronged test that applies when a non-custodian parent seeks variation of custody based on changed circumstances. It clarifies that demonstrating deterioration in the custodian parent's circumstances or even abandonment of custody is insufficient; the applicant must also affirmatively prove that granting custody to them would be in the children's best interests. The judgment also highlights the court's role as upper guardian and the need for comprehensive evidence about proposed custody arrangements. The case underscores the limitations of the adversarial system in custody matters and advocates for law reform to give minor children a voice in proceedings affecting their welfare.
