Hi, if you have changed your husband's last name, you should change all your husband's last name. To be more sure, you can ask the consultant when making the application
Whatever name you use will be the name you will use through the whole process. So the first thing is you need to have whatever name you are going to use is on your marriage certificate. And this needs to be the legal you want to use and it is on record that is your legal name change. Once you commit to a name that is going to be the name used on all legal documents.
