Clayton v Clayton  NZSC 29,  NZFLR 230, and Clayton v Clayton  NZSC 30,  NZFLR 189. Deborah appeared in the Supreme Court representing Mrs Clayton in this landmark case which resulted in two judgments. This case involved a large number of family trusts created during the course of a long marriage.
The complexity is reflected in the fact that the hearing took three full days of hearing time before the Supreme Court. Commentators have referred to this case as “rewriting the legal landscape” in regard to relationship property and trusts. Mrs Clayton, with Deborah’s advocacy, was successful in regard to all of her major claims. SC 38 2015 – Clayton v Clayton (substantive)
Clayton v Clayton  NZCA 30. Deborah also appeared for Mrs Clayton in the Court of Appeal.

Subsequently, the husband sought leave to appeal to the Supreme Court in regard to all issues decided by the Court of Appeal. He was given limited leave in regard to some issues.

She appeared for the appellant in the leading case on the obligations of disclosure by trustees to beneficiaries in Lambie Trustee Limited v Prudence Anne Addleman  NZSC54, 1 June 2021.

DN & LN v Family Court at Auckland, SL & KQ  NZHC 3165, 1 December 2020 and DN& LN v Family Court at Auckland, SL & KQ  NZHC 1116, 19 May2021. These cases involved judicial review of decisions in the Family Court in regard to a Care of Children case.
Family Court at Auckland v Newton CA50/2021, 24 May 2022. This case involved judicial review of decisions in the Family Court and the determination of whether a psychological report should be obtained under s133 of the Care of Children Act 2004. An appeal was allowed and remitted back to the Family Court for determination. Deborah appeared for the parents in regard to this judicial review proceeding which sought to review the role of lawyer for children and the processes of the Family Court in regard to Care of Children litigation. The case involved arguments in favour of children’s rights.
Thompson v Thompson  NZCA 117,  2 NZLR 741, and Thompson v Thompson  NZSC 26,  1 NZLR 593. Deborah appeared for the husband, Mr. Thompson, in regard to this litigation which involved a single asset dispute being the categorisation of a restraint of trade payment paid to the husband four and a half years after separation when the business, commenced during the marriage, was sold to a private equity firm. All other issues in regard to relationship property and trust property had been settled, but the issue of categorisation of the restraint of trade payment was complex and resulted in litigation at all four Court levels. Mr. Thompson was successful in the Family Court, High Court and Court of Appeal. However, the Supreme Court ruled that although the restraint of trade payment was Mr. Thompson’s separate property, it was appropriate to use a discretion provided under s 9(4) of the Property (Relationships) Act 1976 to reclassify it as relationship property. Thompson v Thompson  NZSC 26
Dixon v Kingsley  NZFC 5135, Dixon v Kingsley  NZFC 9596 and Dixon v Kingsley  NZHC 2044,  NZFLR 1012. In these proceedings, Deborah represented the wife. A key decision in terms of compensation for post-separation contribution. In this case, Deborah argued successfully that the wife who was looking after the two sons of the marriage full-time without any real assistance from her former husband, and running a successful business, which had increased in value since separation, should receive a large compensation payment for that post-separation effort.
The Family Court awarded the wife $750,000 in regard to her post-separation contribution. This award is well in excess of any awards previously awarded under this section.
An interlocutory appeal to the High Court between the same parties concerned the rules in regard to discovery in relationship property proceedings and in particular the degree of relevance required before disclosure would be directed.
