You can use the application to present two name options. The secondary name option can be, for example, a newly coined surname or a surname that you have previously used. You can present another name option in the justification for the application.  

Yes. If you have pending applications to change your forename and surname at the same time, we will process them at the same time. 

Please note, however, that we will process your applications independently of each other. In other words, you can receive a positive decision on one application and a negative decision on the other. 

We will process applications in their order of arrival. In matters related to travelling abroad and obtaining a passport, you can contact the Finnish Border Guard and the police. 

The child’s surname cannot be changed without a special reason if the change of surname would lead to a situation where the child’s name would no longer have any link to the name of either parent. Generally, minor children in a family cannot have different surnames if they are full siblings. A name connection to the members of the family is particularly important for children under 15 years of age. 

A change of name of a minor is usually subject to a fee. 

However, a minor’s surname can be changed free of charge in the following cases:

• A minor child receives the surname or compound surname that both parents have. 
• A minor child receives the surname or compound surname of the parent whose parenthood was not confirmed when we were notified of the child’s personal details. 
• After the adoption is confirmed, the minor child receives the surname or compound surname of the adoptive parents 
• A minor child receives the surname or compound surname of the other parent after paternity has been annulled. 
• The parent of a minor child gets married or registers their partnership, in which case the child gets the parent’s new surname. The processing of the application for free also requires the consent of the parent's spouse.  
• A minor child drops one of the two names in a compound surname after having turned 15. 

The above-mentioned situations are examples. We will examine the appropriateness of each fee on a case-by-case basis. Our consideration is based on the Act on Forenames and Surnames.

You can apply for your cohabiting partner’s surname if you have lived in the same household for at least five years and your partner gives written permission for the change of name. The cohabitation must have been recorded in the Population Information System. 

You may also adopt your spouse’s surname if you have or have had a child together or have had joint custody of a child. In this case, a cohabitation period of five years is not required. Nevertheless, you must live with your spouse when you apply for their surname. In addition, your spouse must give permission for the change of name. 

Your surname is not changed automatically after a divorce. You can apply for your former surname any time you want, even during marriage. 

Applying for a surname that you have had before costs EUR 95. 

You need a report on family relationships to prove that you have an unbroken family connection to the surname you are applying for.  

We will first check whether the connection is evident in the Population Information System. If not, we will ask you for a report on family relationships, i.e., an unbroken chain of official certificates.  

You can order the certificates from the parish to which your ancestors belong, either from the central register of the Evangelical Lutheran or the Orthodox Church of Finland. 

We need to ask the Names Board for a statement if you are applying for a newly coined surname. We also request a statement on surnames that have belonged to the applicant’s ancestor and the latest entry concerning the name has been made in the records in the 19th century. 

We may also request a statement for some other special reason. 

If the statement of the Names Board is not in your favour, you can submit a reply to the statement. We will then solve the matter and make a decision, which you can appeal with the Administrative Court.  

We will change your name in the Population Information System on the day the decision is made. You can check your new name in our Check your information service. After the change of name, you will receive a new Kela card in the post, but you must obtain a new passport, electronic ID card and driving licence yourself.  

The name that has been updated in the Population Information System will be automatically transmitted to a number of authorities within a few days. Please note that a valid non-disclosure for personal safety reasons affects the transfer of the information. If you wish, you can also order a payable extract from the Population Information System as proof of your new name. 

List of the authorities receiving information from the Population Information System  (in Finnish)

Besides authorities, remember to send a notification of your new name to, for example, your building manager, telephone operator, the library, and other companies and parties whose customer or member you are. 

If necessary, also notify foreign authorities of your change of name. Generally, we do not forward information abroad.
