Surname upon marriage 

You must notify the surnames you have chosen when you request an examination of impediments to marriage. In other words, when you get married, you do not need to separately apply for a change of name. A change of name based on marriage is free of charge. 

However, not all choices of surnames are possible as there are limits to what surnames can be chosen upon marriage. You have a wider choice of surnames if you submit an application for a name change. For example, if you would like to adopt a newly coined surname or if only one of you would like to adopt the surname they had before their first marriage, you have to submit a payable application before or after the marriage ceremony.  

You need your spouse’s permission is you would like to adopt their surname or one surname from their compound surname upon your marriage.
