Substitute consent for acknowledging a child: procedure and consequences

Do you want to acknowledge a child, but is the necessary consent of the mother or the child lacking? Subject to statutory conditions, you can ask the district court for substitute consent through a lawyer. The court assesses your position, the interests of the child and the applicable standard. A decision granting the request does not, by itself, make you a legal parent: the acknowledgement must then be completed with the competent authority. Nor does joint parental authority follow automatically in the case of acknowledgement with substitute consent. A carefully prepared request therefore covers both the procedure and the steps that follow.

When is consent to acknowledgement required?

Acknowledgement is subject to age-dependent consent rules. For a child under sixteen, the mother’s consent is required in principle. From the age of twelve, the child’s consent also plays a role. For a child aged sixteen or older, the child’s own consent is central. The precise situation must be assessed, particularly where foreign rules or existing parental ties are involved.

Consent to acknowledgement is something different from agreeing to contact, a passport or a care arrangement. A parent may cooperate on one matter and object on another. So record exactly which consent was requested and why it is lacking. A general dispute about the relationship gives the court little to go on. The procedure revolves around the creation of legal parenthood and the interests that are legally relevant.

Who can request substitute consent?

Not everyone who feels a bond with a child can seek substitute consent on the same ground. The law distinguishes between, among others, the begetter and certain other biological parents with a close personal relationship with the child. For other situations, such as a life partner who consented to an act that may have resulted in the conception, a different statutory standard may apply.

The request must therefore make clear which statutory position you rely on. Biological descent, being the begetter and social parenthood are not synonyms. In the case of sperm donation, for example, not every biological tie is sufficient for the same route. A lawyer assesses who can be the applicant, which facts must be proven and which test the court applies. A standard request that merely states that you are ‘the real parent’ is insufficient for this purpose.

What does the court examine?

The court assesses the applicable statutory basis and the interests involved in the acknowledgement. In the route relevant to the begetter, the factors include the mother’s interest in an undisturbed relationship with the child and the balanced socio-psychological and emotional development of the child. For other statutory routes, the wording of the test may differ.

Acknowledgement is not about a reward for good contact or a punishment for a relationship that has ended. The court looks at specific consequences and circumstances. So describe facts: the background, the existing bond, any concerns, support services involved and available information about the child. Serious objections must be examined seriously, but a general reference to tension between adults is not the same as a fully substantiated legal objection. Both parties must be able to explain their position carefully.

Start by checking existing parenthood

Before a request is filed, it must be established which legal parents the child already has. As a starting point, Dutch law recognises a maximum of two legal parents. If there are already two, a third parent cannot simply be added through a new acknowledgement. Another parentage procedure may be needed first. Strict conditions and time limits may apply.

So request an up-to-date full copy of the birth certificate and check any later annotations. An oral statement that nobody has acknowledged the child is not always sufficient. If another person has recently acknowledged the child, or threatens to do so, tell your lawyer immediately. For the broader topic, we refer you to acknowledgement and annulment of acknowledgement. The correct order prevents a request that cannot solve the existing legal problem.

What role does a DNA test play?

Where biological parenthood is disputed, a DNA test may be relevant. The court can assess whether further investigation is needed and how it should be carried out. Not every home test has the same evidential value as a test in which identity, sampling and the origin of the material can be verified. So discuss in advance which test is suitable.

A biological result does not automatically answer every question. The applicant’s statutory position, existing parenthood and the balancing of interests remain important. Do not collect genetic material in a way that infringes other people’s rights. If a test is not possible or someone refuses to cooperate, the lawyer must discuss what significance the court may attach to this and what other evidence is available. A refusal does not automatically lead to the same conclusion in every case.

The special guardian ad litem represents the child

In parentage cases involving a minor child, a special guardian ad litem (bijzondere curator) may be appointed to represent the child independently. This person is not the lawyer of either parent. The guardian ad litem examines the child’s interests within the parentage question and can inform or advise the district court.

So cooperate carefully with requests for information and make clear which documents support your position. Do not try to instruct the child on what to say to the guardian ad litem. After all, the guardian ad litem must be able to form their own picture. If there are concerns about loyalty pressure or safety, discuss them factually and with supporting evidence. The final decision lies with the court, which also assesses the positions of other parties involved and any further investigations.

Will the child be heard by the court?

The Dutch judiciary (Rechtspraak) states that, under current practice in this procedure, children aged eight and over may be invited for a conversation with the judge. This must be distinguished from the statutory age limits for consent to acknowledgement. The age limit of twelve for consent therefore does not mean that a younger child can never have a voice in the proceedings.

The conversation with the child is intended to give the child room to express their own opinion. The child does not have to choose which adult is right. Explain calmly and in an age-appropriate way what the invitation means and, if in doubt, ask the lawyer how the conversation is organised. Do not make a recording or carry out substantive preparation that puts the child under pressure. The court decides how the information is taken into account in the assessment.

The procedure step by step

The lawyer drafts a petition setting out the facts, the legal basis and the necessary annexes. It states which consent is lacking and why substitution is being requested. The district court involves the interested parties in the case. The other party is given the opportunity to respond. If necessary, the appointment of a special guardian ad litem, an investigation or additional requests for information follow.

At a hearing, positions can be explained and questions can be asked. Not every case proceeds in exactly the same way; the court may adapt the handling to what is needed. A decision then follows. The duration depends, among other things, on any defence, investigations and the court’s schedule. The judiciary mentions a range that can run from a few months to more than a year. Do not treat such an indication as a fixed delivery date for your own case.

Which documents help with the request?

Gather the birth certificate, details of your identity and the existing parental ties, relevant correspondence and any earlier decisions. Add a timeline of the relationship, pregnancy, birth, moments of contact and requests for consent. Also describe who actually cares for the child and what arrangements already exist.

If biological parenthood is disputed, note what evidence is available and whether a test has been discussed. Where there are concerns about the child’s welfare, existing professional reports may be relevant. Only submit documents that have been lawfully obtained and are needed for the question at issue. A file with hundreds of unsorted messages is less useful than a complete selection with context and a clear explanation. Keep the original files so that the content can be verified.

How should you respond to a request as the mother or the child?

A request for substitute consent deserves a substantive response. Have it assessed which legal basis has been used and whether the facts stated are correct. It is important to distinguish specific concerns from sadness or anger about the relationship. Both may be understandable, but they do not automatically have the same legal significance.

Describe what consequences you expect for the child and what that expectation is based on. If you have documents from support services, earlier decisions or relevant correspondence, discuss which of them are useful. Also have it checked whether the applicant actually has the correct statutory position. A lawyer can explain how a defence is submitted and which time limits apply. Do not respond only to the other parent outside the proceedings; the court must receive your position in the proper way.

What happens after the request is granted?

A decision granting the request replaces the required consent within the limits of that decision. This does not automatically complete the act of acknowledgement. The judiciary explains that, after the relevant appeal period has expired and with the necessary documents, the acknowledgement must be arranged at the municipality. Have it checked whether the decision is usable and sufficiently final.

Only the completed acknowledgement establishes legal parenthood in accordance with the applicable rules. So ask who will make the appointment with the municipality, which declaration regarding legal remedies is required and how the deed will be processed. Keep a copy of the deed of acknowledgement. Closing a file immediately after the ruling may mean that the step for which consent was requested is never carried out.

Why does joint parental authority not arise automatically?

The rules under which, since 2023, joint parental authority arises automatically with certain acknowledgements are subject to exceptions. Acknowledgement with substitute consent from the court does not necessarily fall under that automatic route. Parenthood and parental authority must therefore be assessed separately. The person acknowledging the child may not assume, solely on the basis of the deed of acknowledgement, that they can henceforth take part in every important decision.

If you also want joint parental authority, it must be examined which application or procedure is needed for this. That assessment involves different criteria from the acknowledgement itself. Contact and the child’s main residence are also separate matters. It is sensible to mention those goals at the first intake, but not to mix them up legally. That way, you know which decision has already been obtained and which still needs to be requested.

Maintenance, name and nationality after acknowledgement

Legal parenthood can have consequences for maintenance and inheritance. However, determining a specific maintenance amount requires separate financial information and possibly a separate decision. Acknowledgement is not an automatic payment arrangement. Have it clearly recorded which maintenance question remains open.

The name and nationality must also be checked. Where there are foreign ties, the date of acknowledgement, the child’s age and nationality rules can be of great importance. A choice of name may be tied to a particular moment. For those situations, there are explanations on acknowledging a child abroad and double surnames and nationality. This prevents an important consequence from being discovered only after a time limit has expired.

Appeal, costs and agreements about the instruction

Under the applicable rules, an appeal against the decision may be possible. A time limit of three months is often mentioned, but the starting point and the position of the person concerned must be checked. So pass on any decision you receive to your lawyer immediately. Do not wait until a scheduled appointment at the municipality to ask whether the ruling can already be used.

Discuss in advance the lawyer’s fees, the court fee and any investigation costs. Ask whether subsidised legal aid is possible in your situation and which personal contributions or external costs may remain. Make clear whether the instruction also covers the follow-up after the ruling and any proceedings on parental authority. This prevents you from having to find out again, after successful acknowledgement proceedings, who will take care of the necessary next steps.

Practical example: consent is not yet a completed acknowledgement

This example is fictitious. A begetter is refused consent to acknowledgement and requests substitute consent through a lawyer. Biological parenthood has been established, but the mother raises concerns about the child’s development. The district court involves the special guardian ad litem and assesses the specific circumstances.

After the request is granted, it is checked whether an appeal has been lodged and which documents the municipality requires. The acknowledgement then takes place. The lawyer explains that this has not automatically made parental authority joint, and discusses a separate route if that is desired. The case shows why the intake must look further than merely obtaining a court decision: the ultimate goal is a parental tie that has been completed in a legally correct manner, with clarity about the remaining questions.

Your first step

Write down which consent is lacking, how old the child is and which legal parents are already registered. Add any documents received and any deadlines. Also indicate whether there are foreign certificates, another acknowledgement or pending proceedings. Through family law at Arslan, you can discuss which statutory route fits and which supporting documents are needed.

Frequently asked questions

Can I always enforce acknowledgement if I am the biological parent?

No. The law distinguishes between different positions and conditions. Biological descent alone does not answer every question. The court assesses the applicable legal basis, existing parental ties and the relevant interests.

Is the consent of a child aged twelve or over important?

Yes, from the age of twelve, the child’s own consent plays a role in acknowledgement. That is different from the age at which a child can be invited for a conversation at the court. The current procedure also describes invitations from the age of eight.

Do I immediately become a legal parent if the court gives consent?

No. The substitute consent must be followed by the actual acknowledgement with the competent authority. First check the final status of the decision and the required documents. Then keep the deed of acknowledgement.

Do I automatically obtain parental authority after substitute consent?

Not through the general automatic route for certain acknowledgements that has applied since 2023. Acknowledgement with substitute consent requires a separate assessment of parental authority. An additional application or procedure may be necessary.

What does a special guardian ad litem do?

The special guardian ad litem independently represents the minor child in the parentage case. This person does not represent the interests of either parent. The guardian ad litem can investigate the facts and inform the court about the child’s interests.

Can the case be concluded without a DNA test?

That is possible if biological parenthood has been sufficiently established and a test is not necessary. If parentage is disputed, further evidence or a DNA test may come into play. The court assesses what the file requires.
