A common name used long-term and consistently can be officially recorded as a first name under Art. 1:4 BW. In practice, judges usually weigh four factors: duration and consistency of actual use, degree of discrepancy and the inconvenience it causes, origin of the common name, and future-proofing of the desired name. Total costs at Simmelink Lawyers are €899 (€558 attorney fee including VAT plus €341 court fee).
In brief
- The court can record a common name as an official first name under Art. 1:4 BW when the petitioner demonstrates a compelling reason; long-term and consistent actual use plus the discrepancy with the official name are recognized grounds in practice.
- In practice, judges usually weigh four factors: duration and consistency of actual use, degree of discrepancy and inconvenience, origin of the common name, and future-proofing of the desired name.
- Two routes are possible: adding the common name alongside existing first names maintains continuity; full replacement is appropriate when the official name is no longer used in any context.
- The processing time is six weeks to six months from filing; after that, a three-month appeal period applies before the change is final.
- Total costs are €558 including VAT (fixed attorney fee) plus €341 court fee, totaling €899; no surprises afterwards.
When is making a common name official feasible?
Making a common name official is feasible in most configurations when the common name is used long-term and consistently in daily life, and the discrepancy with the official name leads to repeated administrative or social confusion. It is not required that the official name itself be burdensome; it is sufficient that the common name better reflects the actual identity.
Four factors that consistently recur in case law and our files for this type of request:
- Duration and consistency of actual use.
Has the common name been used for years or decades in all contexts: work, school, family, social environment? In practice, we see that requests are stronger when the common name is used consistently in each of those contexts, not just in some of them. - Degree of discrepancy and the inconvenience it causes.
Does the difference between the official name and the common name cause regular confusion with official institutions, healthcare providers, employers, or in international travel and work contacts? Concrete examples of administrative errors or repeated explanations strengthen the petition. - Origin of the common name.
Was the common name given by parents at birth (but not registered), developed over the course of life, originated in an international or work context, or a shortened version of the official name? The origin partly determines the evidentiary path. - Future-proofing of the desired name.
Does the common name suit the identity and social position of the Client in the long term? In our experience, judges look not only at the past but also at the practical benefits and social clarity the change provides in the future.
When these four factors are sufficiently met and the desired name complies with birth certificate requirements (not inappropriate, not confusing with a surname), approval is feasible in most cases.
What are the legal considerations when making a common name official?
The legal basis is found in Art. 1:4 BW. The court can order a change or addition of a first name when the petitioner demonstrates a compelling reason. A common name that is used actually and long-term is, in practice, among the structurally recognized grounds, as the discrepancy between the official name and the actual name used recognizably leads to administrative and social burden.
Three characteristics make the common name theme practically distinct.
Adding versus replacing has direct implications for the file
Addition preserves the official name on the birth certificate alongside the common name; this route is appropriate when the official name is still used (for example, by a parent or grandparent) or when the Client desires the continuity of both names. Replacement discards the official name; this route is appropriate when the official name is no longer used in any context and only leads to administrative burden.
Evidence focus is on actual use rather than statements
In most first name change routes, the emphasis is on personal motivation or practitioner statements. In common name requests, the emphasis shifts to objective documentation of actual use: email correspondence, employer statements, school documents, social media registrations, international travel documents. The combination of these documents usually forms the central substantiation.
International and work contexts provide additional functional interest
When the official name leads to pronunciation problems, customer confusion, or cultural complications in an international work environment, functional interest appears alongside identity interest. In files, we see that this combination is usually sufficient for the court, even with shorter periods of use.
Evidence and its weight in files
| Employer statement or employment contract in the common name | Continuity of actual use in a professional context | Usually significant; objective and not self-chosen, with a datable usage history |
| School documents, diplomas, or correspondence from educational institutions | Early and long-term use in a formal context | Usually significant for the “early childhood” origin route; shows consistency across life stages |
| Email correspondence, social media profiles, business cards | Daily actual use in informal and semi-formal contexts | Additional weight; stronger with longer periods and across multiple channels simultaneously |
| Statements from family, friends, or immediate surroundings | Social recognizability and identity alignment | Additional weight; stronger with multiple independent statements from different circles |
| Evidence of administrative confusion (incorrect registrations, explanatory correspondence) | The concrete inconvenience of the discrepancy | Additional weight specifically for the “discrepancy and inconvenience” factor |
| International documents or work correspondence in which the official name leads to pronunciation problems | Functional interest in an international or multilingual context | Usually significant for the international work route; combines identity and functional interest |
Examples from our Practice
The examples below are anonymized and compiled from multiple cases in our practice.
Client with a common name used consistently in all contexts for fifty years
A Client had official first names registered at birth but never actually used. The common name, which the parents had intended as the name for use at birth, was not on the birth certificate. The petition included employer statements, decades-old school documents, and correspondence in which only the common name appeared.
Client with persistent discrepancy between passport and daily use
A Client had an official first name that was not used in any context, including within the family circle. With every identification, hospital visit, or international trip, it had to be explained that the name on the passport differed from the name by which they were known. The petition was substantiated with a chronological overview of administrative errors and moments of explanation over a period of several years.
Client with common name forgotten during birth registration
In one file, the intended common name was not included in the birth registration, even though the parents had intended it to be the first name. The official name that was registered was never used. The motivation focused on the parents’ original intention, combined with decades of actual use of the intended common name.
Client with international common name in a work context
A Client worked in an international environment where the official Dutch first name led to pronunciation problems for colleagues and customers in multiple countries. Over the years, the Client had adopted an international variant used on business cards, email correspondence, and LinkedIn. The petition was substantiated with an employer statement, international customer correspondence, and an explanation of the functional interest of the name change in the specific work context.
Two patterns we regularly see in our practice.
In files where the common name has been used consistently in all contexts for five years or more, we more often see the request handled with limited additional substantiation; for shorter or inconsistent periods of use, the petition requires more extensive documentation. Also: in international work contexts where the official name leads to pronunciation problems or cultural confusion, files show that the combination of actual use and functional interest is usually sufficient for the court, even with shorter periods of use.
How does the procedure work step-by-step?
The procedure takes place via a petition to the court and is filed by an attorney.
- Consultation or intake interview.
In an initial consultation or intake interview, we map out your situation: how long and in which contexts the common name has been used, what discrepancy the official name causes, the origin of the common name, and what substantiation is already available. You will receive an assessment of feasibility and a clear cost overview. - Strategic choices beforehand.
Two choices play a role. First: adding versus replacing. Addition preserves the official name on the birth certificate; replacement discards the official name. The choice depends on whether the official name is still used in any context. Second: timing in relation to an approaching administrative milestone (marriage, graduation, international move, or work relationship). Changing before the milestone prevents later corrections on multiple documents. We discuss these choices before the petition is drafted. - Collecting documents.
We help you organize all necessary documents: a recent birth certificate, a BRP extract, a valid ID, and the substantive substantiation of actual use (employer statement, school documents, email correspondence, social media registrations, any international documents, and witness statements). - Drafting the petition.
The attorney drafts the petition with the legal basis (Art. 1:4 BW), the compelling reason, the four factors applied to your situation, and the desired route (addition or replacement). - Filing with the court.
We file the petition with the court in your place of residence. Requests for a first name change are handled without a hearing in the vast majority of cases. - Court order and waiting period.
The court issues a ruling. If granted, a three-month appeal period applies. After that period, the change is final. - Processing in the BRP and official documents.
After the appeal period has expired, the change is added as a subsequent mention to the birth certificate and registered in the Personal Records Database (BRP). You can then have your passport, ID card, driver’s license, and other documentation updated. A full overview of the first name change procedure and the legal conditions can be found on our main page.

Frequently Asked Questions
There is no legal minimum. In practice, we see that requests with five years or more of consistent use in all contexts are handled with limited additional substantiation; for shorter periods, the petition requires more extensive documentation and additional substantiation of functional or identity interest.
Not automatically. You can choose to add the common name alongside existing first names; in that case, both names remain on official documents. You can also choose full replacement; then the official name is discarded. Which route is appropriate depends on whether the official name is still used in any context.
Yes, and that is usually recommended. Employer statements, employment contracts, school documents, diplomas, and correspondence in the common name are objective pieces of evidence that demonstrate the duration and consistency of actual use. We advise on which documentation carries the most weight in your situation.
Yes. A shortened or informal version of the official name (for example, Tom as a shortening of Thomas, or Liz as a shortening of Elisabeth) can be officially recorded via this route, provided the request is sufficiently substantiated with actual use. The court assesses whether the desired name is not inappropriate and whether a compelling reason exists.
International and work contexts provide an additional functional interest alongside the identity interest. When your official name leads to pronunciation problems, customer confusion, or cultural complications in an international work environment, this constitutes independent substantiation that can compensate for the duration requirement. We advise on how the international work context is phrased in the petition.
In most cases, no. Requests for a first name change are usually handled in writing. If the judge deems an oral hearing necessary, the attorney will guide you through it.
Other applications with their own handling
Not every desire to add a first name is about the actual use of a common name. For other configurations, we refer you to:
- Adding a second first name without actual use.
When the desired name has not been used long-term but is added, for example, as a tribute, namesake, or for family consistency, we handle this on the adding a second first name page. - Spelling error or incorrect registration.
For the correction of a demonstrable clerical error or incorrect registration during birth notification, we refer to correcting a spelling error in a first name.
