New inheritance law in December 2025: What changes for heirs

The café was nearly deserted when Claire opened the letter from the notary.

Her father had passed away three months before. She had wept, sorted through his shirts and cleared out the garage. She believed the hardest part was over. Then she saw the phrase “new law on inheritance coming into force in December 2025”, and her stomach tightened. The solicitor mentioned “reserved shares”, “digital assets” and “compulsory disclosure to descendants”. Cups clinked around her, while somebody laughed at the neighbouring table. Yet her own world was changing completely. Beside her, her brother searched on his phone for what the law would mean for them. The same line filled the screen: “This changes everything for heirs.” Looking up, Claire asked the question that an increasing number of families will soon be asking.

The quiet revolution of December 2025

During the coming year, thousands of families will find that inheritance is no longer simply a matter of an old will and a property to share. The new inheritance law coming into force in December 2025 redraws the position of descendants. It affects who receives what, when they receive it and how open parents must be during their lifetime. Solicitors call it a “rebalancing” of the deceased’s wishes and heirs’ rights. Children who once felt excluded from the process will suddenly have more influence. Parents who assumed they could divide their property however they wished will discover that the rules are stricter. This change may not dominate the headlines each day. Nevertheless, it will discreetly reshape family discussions at Christmas.

Consider the Martin family, a fairly typical middle-class household. They have a modest home that is almost mortgage-free, a life insurance policy, a rental flat and some savings. Under the previous system, the father had made a will leaving a substantial portion to his youngest son, who had “taken care of everything at the end”. His eldest daughter, who lived further away, might only have learnt of the unequal arrangement after the funeral and could have challenged it, leading to months of strained relations. Under the new law, the notary must check more rigorously that every child’s statutory reserved share is safeguarded and that lifetime gifts are properly recorded and included. It becomes more difficult to conceal the issue of the “forgotten child”. Even the father’s digital portfolio on a trading app must now be declared and valued within the estate.

At its heart, the shift concerns the balance of power. The law strengthens the principle that descendants are not merely optional beneficiaries, but parties with minimum rights that cannot secretly be avoided. It encourages parents to plan sooner, record gifts and explain their decisions while alive instead of leaving a future family crisis. It also requires each heir to abandon a form of comfortable unawareness: there can be no more shrugging and saying, “We’ll see when the time comes.” That time is approaching, with firm rules, deadlines and formalities that have real consequences. The new inheritance law doesn’t care about old family myths - it only cares about what is written and what is proved. For many people, this will be a harsh awakening.

How to prepare for the new inheritance law before December 2025

Before the law takes effect, the most useful step is remarkably straightforward: set out your prospective estate on a single sheet of paper. It need not be a spreadsheet or a 40-page document. On one page, note what you own - your home, savings, life insurance, business shares, cryptocurrency and car - who you expect to inherit, and roughly what you would like each person to receive. Take this sheet to a notary or inheritance solicitor, then ask one direct question: “With the new law, where are the problems?” This practical task often uncovers overlooked assets, out-of-date policy beneficiaries or a will that no longer reflects your circumstances. It converts an abstract “new law” into specific figures and people, while giving you time to put matters right.

People repeatedly make the same mistakes, and they are deeply human ones. Parents avoid inheritance discussions with their children because they fear it will feel like counting down to their death. Adult children hesitate to raise questions in case they appear greedy. The issue is therefore pushed aside. When illness or death arrives, everything then erupts together: forms, grief and resentments that have built up for years. The new law will not remove these problems, but it will make silence more expensive. With more clearly defined deadlines for declaring, challenging or accepting terms, a family that decides to “see later” may lose rights simply by doing nothing. Let us be honest: nobody really deals with this every day. Estate planning can seem dull, distant and almost improper. Even so, one afternoon spent gaining clarity may prevent ten years of resentment.

One notary described the purpose of the reform in these terms:

“The law now assumes that descendants have a right to understand and a right to a minimum share. The era of secret arrangements that magically resolve everything after death is over.”

• Talk early: Start one calm discussion with parents or children before December 2025, even if it feels uncomfortable.
• Check paperwork: Review wills, marriage contracts and life insurance beneficiaries, updating anything more than five years old.
• Trace gifts: Record every substantial lifetime gift or loan made to each child; these may be rebalanced under the new rules.
• Consider the digital world: Identify all online accounts with financial value that heirs will need to access.
• Ask for a simulation: Ask a notary for a written illustration of how the estate would be divided under the new law.

What the reform means emotionally for heirs and parents

This reform is not merely a technical matter involving tax and percentages. It reaches deeply personal questions: Which child do I trust most? Who “deserves” more because they gave up their time? How can I support a vulnerable child without disadvantaging the others? On a difficult day, inheritance may feel like a judgement on an entire life. As the new rules provide descendants with more secure minimum rights, some parents may feel constrained. They fear they will no longer be able to reward the child who contributed most or provide greater support to a disabled grandchild. The reality is more complex: the law establishes a floor, rather than a ceiling. It continues to allow tailored decisions, but those decisions must be considered carefully, documented and explained. It encourages families to talk where silence once prevailed.

FAQ:

• What exactly changes for children with the December 2025 law? The law reinforces descendants’ protected share and imposes tighter scrutiny on gifts and nominations intended to circumvent it. Children are more difficult to disinherit and have clearer ways to dispute unfair arrangements.
• Can parents still favour one child over the others? Yes, within limits. They must preserve the legal minimum for every descendant, but retain a “free portion” that they may distribute more flexibly, provided gifts and intentions are properly documented.
• What happens to digital assets like crypto or online trading accounts? They form part of the estate in the same way as any other financial asset. Heirs and notaries will require information and access details to value them and include them in the distribution.
• Is it mandatory to change my will before December 2025? No, although a will that conflicts with the new rules may be partly invalid or interpreted differently. A review is strongly recommended to prevent legal and family complications.
• How can I talk about this with my parents without sounding interested in their money? Emphasise practical peace of mind: explain that you want to prevent later disputes between siblings, would prefer their wishes to be clear and believe that a meeting with a notary could safeguard everyone.
