T (A Child) (Abduction: Habitual Residence following Relocation: Objections to Return), Re

Facts

T is a boy born in September 2012, now aged 13½, whose father is a British national living in Hungary and whose mother is a Polish national living in England. His mother has been his primary carer for the vast majority of his life, and he has lived in England for 11½ of his 13½ years. The parents married and, towards the end of the marriage, moved from England to Hungary for the father's work; in 2019 the mother and T returned to this jurisdiction with the father's agreement, the father remaining in Hungary, where he has since formed a new relationship and had two further children. In May 2025, following a falling-out between T and his mother, T moved to Hungary to live with his father in what the court found to be ambiguous circumstances: the move was first mooted at the start of May and accomplished by the half-term, with no school place initially available. T began at a Hungarian school on 21 August 2025. By agreement, he travelled to England around his birthday for what was intended to be a week, and was due to return on 28 September 2025. He did not return; the mother wrote to the father that day communicating T's decision. The father applied promptly under the 1980 Hague Convention for T's return to Hungary, T being separately represented through a guardian.
