Case Summary – Spousal Maintenance and Child Support Departure Orders

24 March 2025

“While acknowledging the significant income gap between the parties, the Court found that the applicant’s financial future was sufficiently secured through the property settlement. The refusal of ongoing spousal maintenance and periodic child support adjustment reflected a careful balancing of fairness, finality, and evidence-based decision-making. Ultimately, the case highlights the need for clarity and documentation in claims relating to post-separation financial support.” – Carswell & Tenson (No 4) [2024] FedCFamC1F 848

Carswell & Tenson (No 4) [2024] FedCFamC1F 848

Introduction

The case Carswell v Tenson (No 4) [2024] FedCFamC1F 848 concerns significant issues in family law, particularly property settlement, child support departure orders, and spousal maintenance. The Federal Circuit and Family Court of Australia (Division 1) presided over the matter, with Curran J delivering the judgment on 6 December 2024. This case highlights the balancing act between financial disparity post-separation, child support obligations, and the principle of finality in financial disputes.

Background

The proceedings involved Ms Carswell (the applicant) and Mr Tenson (the respondent), who had been in a long-term de facto relationship that ended in 2018. They have two children, aged 12 and 10, who primarily reside with Ms Carswell. Following the breakdown of their relationship, disputes arose over financial matters, culminating in this fourth set of proceedings regarding property division, child support arrangements, and a spousal maintenance claim.

Throughout their relationship, the parties accumulated a range of assets, including real property, superannuation, and business interests, while also incurring mortgage and loan liabilities. A notable aspect of the case was the significant income disparity between the parties. Mr Tenson, a highly qualified medical specialist, earns over $500,000 per year, whereas Ms Carswell, who works part-time as an administrative assistant, earns approximately $45,000 annually. This disparity played a key role in the legal arguments regarding financial entitlements and obligations post-separation.

Prior court determinations had addressed interim parenting arrangements, financial support, and preliminary property settlements. This judgment specifically dealt with the final division of property, child support departure applications, and the spousal maintenance claim brought forward by Ms Carswell.

Key Legal Issues and Questions for the Court

The Court had to consider:

  1. Property Settlement: Whether the division of assets and liabilities should be adjusted under section 79 of the Family Law Act 1975 (Cth), considering financial and non-financial contributions, future financial needs, and the justice and equity of the division under section 75(2).
  2. Child Support Departure Order: Whether there were sufficient grounds under sections 116 and 117 of the Child Support (Assessment) Act 1989 (Cth) to justify a departure from the standard child support assessment, particularly in relation to private school fees and extraordinary expenses for the children.
  3. Spousal Maintenance: Whether the applicant was entitled to periodic or lump sum spousal maintenance under sections 72 and 74 of the Family Law Act 1975 (Cth), based on her financial needs, ability to support herself, and the respondent’s capacity to provide such support.

Case Authorities and Cited Precedents

The court referred to several key precedents to assess contributions, financial adjustments, and maintenance claims:

  1. Astbury v Astbury [1978] FamCA 28; (1978) 4 Fam LR 395 – Considered future financial needs in property settlements, which was relevant in assessing Ms Carswell’s lower earning capacity.

Court’s Findings

After reviewing the evidence, the court made the following determinations:

  1. Property Adjustment – The court ordered a property division in favor of Ms. Carswell, considering her primary caregiving role and lower earning capacity. However, it emphasized that Mr. Tenson’s significant earning potential did not justify an excessive adjustment.
  2. Child Support Departure Order – The court granted a non-periodic child support departure order but refused the periodic departure order. The judge found that the applicant demonstrated sufficient grounds for a one-time financial adjustment but failed to prove a necessity for ongoing modifications.
  3. Spousal Maintenance – The application for spousal maintenance was refused. The court determined that some of Ms. Carswell’s claimed expenses were unsubstantiated or unreasonable, and she had substantial financial resources available post-property settlement.

Legal Implications and Precedent Summary

This decision reinforces several legal principles. Courts carefully consider both financial and non-financial contributions in property settlements, particularly in cases where one party has assumed a primary caregiving role. Departure orders for child support require a strong evidentiary basis, especially for non-periodic claims that go beyond standard assessments. Additionally, applicants seeking spousal maintenance must demonstrate a clear inability to support themselves post-settlement.

This case serves as a precedent for disputes involving significant income disparities and caregiving responsibilities, providing guidance on balancing financial obligations post-separation.
