Yes, a parent can sell to a child, but the price must be genuine and near market value. A clear undervalue can be re-characterised by the tax authority as a disguised gift, and if any other children are not consulted it may be challenged as unfair (Notaire.be, 2026).
Selling to your own child is perfectly legal, and sometimes practical, but Belgian law treats it with care because the family relationship creates room for abuse. A real sale means a real price paid and received. If the property is passed for a fraction of its worth, the tax administration can look through the transaction and treat the shortfall as a disguised gift (donation déguisée), applying gift duty on the discount and potentially penalties. Documenting an arm’s-length value is therefore not optional, it is protection.
The second pitfall is fairness between children. Under Belgian succession law, children are protected heirs with a reserved share of the estate. A sale to one child at an undervalue can effectively favour that child at the expense of the others, and on the parent’s death the disadvantaged heirs can seek to have the advantage brought back into account (rapport or réduction). The counter-intuitive point is that a well-intentioned family deal can quietly plant a future inheritance dispute unless it is either priced fairly or openly structured, with the other children’s knowledge, as an advance on their inheritance.
There is a tax nuance worth knowing. When property is sold rather than gifted, the buyer pays registration duty, and Walloon registration duty on a buyer’s own and sole home was reduced to 3% since 1 January 2025 (wallonie.be, 2025). By contrast, a gift attracts gift duty on the full value. Which is cheaper depends on the family’s goals, the value involved and whether income needs to be raised, which is exactly why parents should compare a genuine sale against a gift before deciding.
The clean way to do it is simple: obtain an independent valuation, set a defensible price, and involve a notary who can flag succession and tax consequences and, where appropriate, record the arrangement transparently. Done properly, a sale to a child is straightforward; done carelessly, it invites two authorities and several siblings to intervene.
At a glance
- A parent can legally sell to a child, at a genuine, market-based price.
- A clear undervalue risks being re-characterised as a disguised gift with duty and penalties.
- Children are protected heirs; an undervalued sale can be challenged by other siblings.
- On a real sale the child pays registration duty, reduced to 3% for their own and sole home since 2025 (wallonie.be, 2025).
- A gift instead attracts gift duty on the full value; compare both routes.
- Get an independent valuation and set a defensible price.
- Involve a notary to manage succession and tax consequences transparently.
