She didn't necessarily take care of it yet. My sister in law was separated for over 10 years before she dealt with it. What finally motivated her was a very serious (and continuing to progress) relationship. And she didn't have to travel to another country. All she had to do was take the paperwork to the local authorities.
Keep in mind that there is a child involved. As long as there was no pressing need to do it she was better off in some ways just leaving it be.
