Step-by-step guide: How to prepare your application for family reunification

Applying for family reunification in Denmark can seem like a challenging and emotional process. For many families, it is not just about paperwork, but about being able to be with their loved ones and creating a life in safety. The process can, however, be complex, and even small mistakes in the application can lead to delays or refusals. That is why it is important to be thoroughly prepared before submitting your application.
This guide goes through, step by step, how to prepare your application for family reunification, which documents you need, and how a legal advisor in family reunification can help you avoid mistakes and increase your chances of success.

Step 1: Understand the rules and requirements

Before you start filling out your application, you should familiarise yourself with the applicable rules for family reunification. The Danish Immigration Service has a number of requirements that must be met, depending on whether you are applying for family reunification as a spouse, cohabiting partner, parent, or child.
The most common requirements include:

  • That you live in a genuine and stable relationship
  • That the person residing in Denmark has a permanent address in Denmark
  • That you have the ability to support yourselves financially
  • That suitable housing conditions are available
  • That there are no serious criminal records or security risks

The rules can change continuously, and therefore it is always recommended to seek advice from a professional, so you can be sure that your application meets the current conditions.

Step 2: Gathering documentation

A large part of the work with family reunification involves gathering the right documentation. Here is an overview of the most common documents you must attach:

  • Valid copy of passport for both parties
  • Marriage certificate or documentation of cohabitation
  • Documentation of housing conditions (rental contract, ownership, etc.)
  • Documentation of finances (payslips, bank statements, employment contract)
  • Birth certificates for any children
  • Photos, letters, and other documentation of the duration and nature of the relationship

Here, a legal advisor in family reunification can help you ensure that you submit the correct documents and avoid mistakes that can often lead to delays. Many applicants experience that their case drags out simply because a single document is missing or has not been translated correctly.

Step 3: Complete the application correctly

When you fill out the application form, you must be very careful with the information. Even small mistakes, such as incorrect dates, spelling errors in names, or missing fields, can mean that the application is rejected as incomplete.
Remember to double-check:

  • All personal information
  • Contact information
  • Dates of marriage or cohabitation
  • Any previous residence permits or visas

It is also important to use the correct application form depending on your situation. You can find these on the Danish Immigration Service’s website, but it can be a good idea to have a professional look it over before you submit it.

Step 4: Get legal guidance along the way

Even if you feel confident about how to fill out the application, professional advice can make a significant difference. An immigration law legal advisor in Denmark, or an immigration law lawyer in Denmark, or a family reunification lawyer, or family reunification legal advice, has insight into the legislation and experience with how cases are handled in practice.
Legal advice, and a family reunification lawyer, can help you:

  • Understand how the rules apply in your specific situation
  • Ensure that all documents are correct and up to date
  • Prepare a strong application with legal precision
  • Avoid typical mistakes that can lead to refusal

An experienced legal advisor in family reunification or a lawyer in family reunification can also help if you have already received a refusal and wish to appeal to the Immigration Appeals Board. In that case, it is crucial that your appeal is legally correctly formulated and contains the necessary documentation.

Step 5: Be patient – but follow up

The processing time for family reunification can vary depending on the complexity of the case and the workload of the authorities. It can take anywhere from a few months to over a year. During this period, it is important to be patient, while at the same time keeping an eye on your case.
You can:

  • Follow your case status on the Danish Immigration Service’s portal
  • Make sure to respond quickly if the authorities request supplementary information
  • Contact your legal advisor to get status updates or advice along the way

Patience and good communication are the key to a successful process.
