The Autumn Budget 2025: What it means for Family Law

The Autumn Budget 2025 does not directly reform the core statutes that govern family law, such as divorce processes, child arrangements, or adoption. However, it introduces several tax, welfare and inheritance-related measures that will have a substantial indirect impact on families and those advising them.

Key Budget-Driven Changes Relevant to Family Law

Abolition of the Two-Child Benefit Cap (from April 2026)

The Budget removes the limit that previously restricted welfare support to the first two children in most households. For separated parents, this may alter income projections, which means maintenance orders and child support calculations may require reassessment.

Financial Settlements, Divorce, Separation and Income Stability

The Budget maintains the freeze on personal income-tax thresholds. For couples going through a divorce or separation, this creates fresh challenges when forecasting future income. Traditional maintenance calculations may no longer be reliable, and settlement agreements may need greater flexibility and periodic review mechanisms.

Estate Planning, Inheritance and Long-Term Family Security

The Budget confirms that Inheritance Tax thresholds will remain frozen until at least April 2031. As asset values rise, this will increase the number of estates that fall within the scope of inheritance tax. This may affect decisions involving wills, trusts, and lifetime gifts. Family-law professionals advising on divorce or estate planning may need to review wills sooner rather than later.

High-Value Property Owners and the Impact on Family Housing Stability

The Budget also introduces an annual high-value property surcharge ('mansion tax') for residential properties valued above £2 million, from April 2028. Families owning high-value property, especially those in financial remedy proceedings, may see ongoing ownership costs increase, influencing decisions on whether to retain, sell or transfer such properties after separation.

Practical Takeaways for Families and Family-Law Practitioners

• Review maintenance projections to reflect future inflation, frozen tax thresholds, and benefit changes.
• Seek financial disclosure that includes long-term cost projections for housing, tax, and maintenance obligations.
• Revisit child support arrangements from 2026, as increasing benefit income may alter maintenance calculations.
• Review wills, trusts and gifting strategies in light of the inheritance tax freeze.
• Factor in the upcoming surcharge on high-value properties when making decisions regarding home retention or transfers of ownership.
