Inheritance in Belgium: How to Inherit Step by Step
Every year in Belgium, more than 130,000 estates are opened following a death. Yet few families truly know what to expect: who inherits what, within what timeframe, and how much it will cost. The result? Costly mistakes, missed deadlines, and sometimes conflicts that fracture family relationships for years. Inheritance in Belgium is far more than a simple transfer of assets. It is a legal process governed by the Belgian Civil Code — Articles 870 and following — which follows precise rules, with deadlines to respect, taxes to pay, and decisions with far-reaching consequences. Accepting an indebted estate without due care risks having to repay the deceased's debts from your own pocket. Renouncing it in error may mean letting go of an inheritance that was rightfully yours. Whether you are an heir to an estate that has just been opened, or you are planning the future of your loved ones, this guide explains everything — clearly, concretely, and without unnecessary jargon — so that you can navigate the Belgian succession process with full confidence.

Accepting or Renouncing an Inheritance
People often imagine that inheriting is good news. But some estates conceal debts that exceed the assets — and accepting without careful thought can cost you dearly. Belgian law fortunately offers you three options, and you have a period of time within which to decide how to proceed.
The three options available to you
Unconditional acceptance: you accept the estate in its entirety, assets and liabilities. If the deceased had €50,000 in debts and only €20,000 in assets, you will be required to make up the difference from your own funds. This is the simplest route, but also the most risky if the deceased's financial situation is unclear.
Acceptance under benefit of inventory: this is the cautious approach — and often the best one when you have doubts. You accept the estate, but your liability for debts is limited to the value of the assets inherited. A notary draws up a full inventory of the estate. This procedure costs between €800 and €3,000 depending on complexity, but it offers effective protection.
Renunciation: you waive all your rights to the estate, as though you had never been an heir. You inherit nothing — neither assets nor debts. Your own children may then take your place by representation.
Deadlines: do not miss them
You generally have 4 months from the date of death to make your decision — a period that can be extended by the court if you make a formal request. During this time, no creditor can compel you to act. However, if you behave as an owner of the assets (selling a piece of furniture, collecting rent), you will be deemed to have tacitly accepted the estate.

Inheritance Tax Payable in Belgium
This is often the question that causes the most concern: how much will it cost? In Belgium, inheritance tax is a regional matter — it is the Regions (Wallonia, Flanders, Brussels-Capital) that set the rates, and these can differ significantly from one region to another. The deceased's tax domicile — not that of the heirs — determines which region has jurisdiction.
The rates: what changes according to your family relationship
The principle is straightforward: the closer you are to the deceased, the less you pay. And vice versa.
In the Brussels-Capital Region, by way of example:
- Between spouses and legal cohabitants: from 3% (up to €50,000) to 30% (above €500,000)
- In the direct line (parents-children): from 3% to 30% depending on the bracket
- Between brothers and sisters: from 20% to 65% — yes, up to 65%
- Between strangers (no family relationship): from 40% to 80%
Wallonia and Flanders apply slightly different scales, with certain specific exemptions — notably in Flanders for the transfer of a family business, which may benefit from a reduced rate of 3% subject to strict conditions.
What you can deduct
Certain liabilities of the deceased are deductible from the taxable base: proven debts, funeral expenses (within a certain limit), and in some cases mortgage charges. A notary or a specialist tax lawyer can legally optimise your position and reduce the bill.
Immovable property: be mindful of payment deadlines
Inheritance tax must be paid within 4 months of the date of death (or within 2 months of the registration of the succession declaration if later). Payment facilities are available, but must be explicitly requested. Certain banks also offer specific loans to finance this tax when heirs lack liquidity — a common situation when the estate consists primarily of immovable property.

Questions fréquentes
How long do I have to accept or renounce an inheritance in Belgium?
In principle, you have 4 months from the date of death to make your decision. This period can be extended upon application to the court. Please note: certain acts — collecting rent, selling an asset — may constitute tacit acceptance, even before the deadline has expired.
What happens if I do not file my succession declaration within the prescribed deadlines?
Late payment interest of 7% per annum applies automatically to the tax due. The standard deadline is 4 months from the date of death if the death occurred in Belgium. Administrative penalties may also be added depending on the competent region.
What does inheriting 'under benefit of inventory' mean, and is it always useful?
It is a form of acceptance that limits your liability for debts to the value of the inherited assets. You are never at risk of paying the deceased's debts from your own funds. This is particularly useful when you are unaware of the true extent of the deceased's debts — and it costs between €800 and €3,000 in notary fees.
Do I need to pay inheritance tax in Belgium, and how much?
Yes, inheritance tax is mandatory in Belgium, but the rate depends on your relationship to the deceased and your region of residence (Flanders, Wallonia, or Brussels-Capital). Spouses and children typically benefit from lower rates or exemptions, while more distant relatives pay significantly higher percentages. nexlaw.be can help you understand your specific tax obligations and optimize your declaration.
What is the difference between inheriting by law and inheriting by will in Belgium?
Inheriting by law (succession ab intestato) follows the legal order: spouse and children first, then parents, siblings, and more distant relatives. Inheriting by will allows the deceased to distribute assets according to their wishes, though certain family members (spouse, children) have protected rights called the 'reserved portion' that cannot be entirely disinherited. Both routes require proper declaration to the Belgian tax authorities within the 4-month deadline.
Can I renounce an inheritance if the deceased had significant debts?
Yes, you can formally renounce (decline) an inheritance within 4 months of death, which protects you from inheriting any debts. Alternatively, you can accept 'under benefit of inventory' to limit your liability to the inherited assets' value. If you've already made tacit acceptance through asset management, renunciation may no longer be possible, so act quickly and consider consulting a notary.
What happens to an inheritance if the heir dies before accepting or renouncing it?
If an heir dies before the 4-month deadline expires, their right to accept or renounce typically passes to their own heirs or estate. This means the decision responsibility transfers to the next generation. The timeline for the original inheritance decision generally continues from the original death date, so immediate action by the deceased heir's representatives is essential.
