Introduction

The Child Support Agency (CSA) conducts Capacity to Pay (CTP) investigations when they suspect a parent may have a greater capacity to pay child support than their declared income suggests. These investigations can be complex and stressful for fathers. Understanding the process and your rights is essential for navigating CTP investigations effectively.

What is a Capacity to Pay Investigation?

A CTP investigation is a detailed examination of your financial circumstances to determine if you have the capacity to pay more child support than your current assessment indicates. The CSA may investigate when:

  • Your declared income seems inconsistent with your lifestyle
  • There are allegations of income minimization
  • You have significant assets but low declared income
  • There are concerns about undeclared income sources
  • Your ex-partner has raised concerns about your financial capacity

Common Investigation Triggers

  • Lifestyle inconsistent with declared income
  • Ownership of expensive assets (cars, boats, property)
  • Business ownership with minimal declared income
  • Frequent overseas travel
  • Large cash transactions or purchases
  • Complaints from the other parent

The Investigation Process

Initial Contact

The CSA will typically:

  • Send you a letter explaining the investigation
  • Request specific financial documents
  • Set deadlines for providing information
  • Explain the potential consequences
  • Provide contact details for the investigating officer

Information Gathering

During the investigation, the CSA may:

  • Request bank statements and financial records
  • Examine tax returns and business records
  • Contact third parties (employers, banks, accountants)
  • Review asset ownership and transactions
  • Investigate lifestyle and spending patterns
  • Gather information about new partners' finances

Assessment and Decision

The CSA will:

  • Analyze all gathered information
  • Determine your actual capacity to pay
  • Make a decision about your child support assessment
  • Notify you of the outcome in writing
  • Explain reasons for any changes

Possible Outcomes
