Naturalisation without renunciation of nationality: When loss of proprietary rights forms a legal exception

Loss of proprietary rights as a ground for exemption from the Dutch renunciation requirement

When applying for Dutch naturalisation, the general rule is that the applicant must renounce their original nationality. This so-called renunciation requirement is a core element of Dutch nationality law.

However, this requirement is not absolute. The Netherlands Nationality Act and the accompanying policy manual recognise several exceptions to the renunciation requirement. These exceptions apply in situations such as legal impossibility, disproportionate costs, or serious adverse consequences.

One of the more complex and technical exceptions applies where renouncing nationality would lead to the loss of proprietary rights (vermogensrechtelijke rechten) and thereby cause substantial financial disadvantage.

This blog focuses specifically on that ground for exemption. Other exceptions to the renunciation requirement can be addressed separately.

What are “Proprietary Rights” in the context of naturalisation?

This exception applies where the applicant can demonstrate that renouncing their original nationality will result in the loss of proprietary rights that already exist at the time the naturalisation application is submitted.

The concept of “proprietary rights” refers to legally enforceable rights of an economic nature — rights that have measurable financial value. It is broader than inheritance rights alone.

Examples may include:

• Loss of ownership of immovable property in the country of origin
• Loss of inheritance rights
• Loss of an existing right to maintenance (alimony)
• Loss of accrued pension rights
• Loss of other established financial entitlements

An applicant who wishes to rely on this exception to the renunciation requirement must sign a declaration stating that they invoke this exemption and that they are not willing to renounce their original nationality.

Proving that the loss will actually occur under foreign law

It is not sufficient to argue that financial loss is possible. The applicant must prove that, under the law of the country of origin, renunciation of nationality leads directly to the loss of the specific proprietary right or asset concerned.

This must be supported by:

• Official documents issued by competent authorities in the country of origin
• Relevant statutory provisions
• Legalised and translated documentation where required

In addition, the applicant must demonstrate that they personally possess the proprietary right or asset in question. This may be done through:

• Official statements from competent authorities (for example, a land registry in the case of real estate)
• A notarial deed (for inheritance rights)
• A court judgment (for maintenance claims)

The applicant must also establish the current market value of the proprietary right or asset that would be lost.

No substantial financial disadvantage if the loss can reasonably be avoided

Not every potential financial loss qualifies as “substantial” within the meaning of Dutch naturalisation policy. A crucial assessment concerns whether the loss is unavoidable.

If an applicant owns real estate in the country of origin that would be lost upon renunciation, but can reasonably sell it beforehand and transfer the proceeds to the Netherlands, there is no substantial financial disadvantage.

The same applies to government benefits or financial entitlements that can be fully liquidated prior to renunciation. Only where the applicant can demonstrate that liquidation or transfer is impossible — or only possible under unreasonably burdensome conditions — will the loss be regarded as unavoidable and therefore relevant.

The 25% test in Dutch naturalisation law: When is the disadvantage “substantial”?

The core financial assessment concerns the relationship between:

• The value of the proprietary rights that would be lost due to renunciation, and
• The applicant’s remaining assets (worldwide).

“Remaining assets” refers to the applicant’s total assets in the Netherlands and abroad that are not affected by renunciation.

The financial disadvantage is considered substantial if the value of the loss is equal to or greater than 25% of the applicant’s remaining assets. If the loss represents less than 25%, the exception to the renunciation requirement will generally not apply.

Importantly, income is not taken into account in this assessment. Only assets are relevant. The rationale is that this exception concerns the loss of existing proprietary rights, not an upfront financial payment.

Minimum and maximum thresholds linked to naturalisation fees

The policy manual also establishes minimum and maximum limits linked to the Dutch naturalisation fees.

• If the loss is equal to or lower than the reduced naturalisation fee (for a single application), the exception cannot be invoked. The loss is considered too limited to qualify as substantial.
• If the loss is equal to or higher than ten times the normal naturalisation fee (for a single application), the exception automatically applies, regardless of the applicant’s total assets.

Between these thresholds, the decisive factor remains the 25% comparison.

Joint naturalisation applications by partners

If partners apply for Dutch naturalisation together, one partner qualifying for the exemption does not automatically mean that the other partner is exempt from the renunciation requirement. Each partner must demonstrate that they personally would lose proprietary rights as a result of renunciation.

If both partners would suffer a loss, the authorities combine:

• The total value of proprietary rights that would be lost by both partners, and
• The total remaining assets of both partners.

The 25% test is then applied to the combined figures. If the combined loss equals or exceeds 25% of the combined remaining assets, both may be exempt. If not, neither qualifies.

A partner who does not personally lose proprietary rights cannot rely on this exception.

Practical implications: Documentation and financial assessment

Invoking this exception requires careful legal and financial preparation. The burden of proof lies with the applicant.

The documentation must clearly establish:

• That renunciation legally leads to loss of the proprietary right
• That liquidation or transfer is not reasonably possible
• The current value of the right or asset
• That the 25% threshold is met

Because foreign legislation, cross-border property law and financial valuation issues are often involved, these cases can be technically demanding.

Naturalisation without renunciation: How Delissen Martens can assist

At Delissen Martens, we assist clients in complex Dutch naturalisation procedures where renunciation of nationality may have significant legal and financial consequences.

These cases often require:

• Analysis of foreign legislation
• Coordination with foreign authorities
• Structured financial calculations
• Careful preparation of documentary evidence

We assess whether the exemption from the renunciation requirement is realistically applicable in your situation, identify evidentiary gaps, coordinate legalisation and translation of documents, and present a well-founded request to the Dutch authorities.

Given that the renunciation requirement and its exceptions are applied strictly, strategic preparation is essential. A carefully substantiated application can make the difference between approval and refusal.
