The 50th Anniversary of the Inheritance Act 1975: A 2025 Retrospective

On 12 November 2025, the Inheritance Act 1975 officially marks half a century of reshaping British probate law. Originally designed to ensure that spouses and children weren’t left destitute, the Act has evolved into the most powerful tool for challenging an unfair Will. This 1,000-word retrospective explores how the “Maintenance Standard” has shifted in 2025 to reflect modern living costs, the impact of the Ilott v The Blue Cross legacy, and why this 50-year-old law is more relevant than ever for blended families and cohabiting partners.

A Half-Century of Fairness over Freedom

In the UK, we value “Testamentary Freedom”, the right to leave your money to whoever you choose, even if that means leaving your children nothing in favour of a local donkey sanctuary. However, for 50 years, the Inheritance Act 1975 has acted as the ultimate “safety net.”

Passed in 1975 to replace more restrictive laws from the 1930s, the Act allows certain people to ask a judge to rewrite a Will if it fails to make “reasonable financial provision” for them. As we celebrate its 50th anniversary in 2025, the Act is no longer just about preventing poverty; it is about ensuring that a person’s responsibilities to their family do not end just because their life has.

The “Maintenance Standard” in 2025

The Act creates two different standards of provision:

1. The Spouse Standard: For husbands, wives, and civil partners, the court asks what is reasonable for them to receive, regardless of whether they “need” it for daily living. This is usually the highest level of award.
2. The Maintenance Standard: For everyone else (children, cohabitees, and financial dependants), the award is limited to what is reasonable for their maintenance.

In 2025, the definition of “maintenance” has expanded. It no longer just covers food and rent. Recent cases have shown that maintenance can include a lump sum to pay off high-interest debts, a fund for medical treatment, or even the costs of retraining for a new career. The court looks at your “financial bridge”, what do you need to get from your current situation to a place of financial security?

The Legacy of Ilott: Adult Children and Estrangement

You cannot talk about the Inheritance Act in 2025 without mentioning the landmark case of Ilott v The Blue Cross. This case proved that an adult child, even one who has been estranged from their parent for decades, can still win a claim if they are in genuine financial need.

However, the 2025 landscape has added a layer of caution. Judges are now more likely to reduce an award if the claimant was “viciously” estranged or if the parent left a clear “Letter of Wishes” explaining why the child was excluded. The lesson for 2025 is clear: “Need” is the lock, but “Conduct” is the key.

FAQs

1. Can I claim under the Act if my partner and I weren’t married?

Yes, provided you were living together “as a married couple” for at least two years immediately before their death. In 2025, cohabitation claims are among the fastest-growing areas of probate litigation as more couples choose not to marry.

2. What is the “6-month rule”?

This is the most dangerous trap in the 1975 Act. You have exactly six months from the date the Grant of Probate is issued to file your claim in court. If you miss this deadline, you usually lose your right to claim forever, unless there are “exceptional circumstances.”

3. Does a “No-Win-No-Fee” agreement cover 1975 Act claims?

Yes, many solicitors offer these agreements for Inheritance Act claims. However, following the Hirachand ruling, remember that you cannot recover the “success fee” from the estate; it will be deducted from your final award.
