Daughter’s Soon-to-be Ex Trying To Use Her Credit

Hi. Here’s the back story. My daughter’s spouse joined the Navy right after they married around 4 years ago. They were high school sweethearts and very young. As expected, it didn’t work out. No kids, thank goodness. They’re friends, too. So that’s good. They decided that things should end a little over a year or so ago. He’s removed her from his insurance, but still collected a paycheck based on them being together. She filed the paperwork to get the ball rolling. Never asked him for a penny and hasn’t received any support from him since they first got married. It has taken awhile to get to this point because they live 36 hours from each other and he’s always deployed on a sub, making communication almost impossible. He informed her that he is trying to buy a home and the real estate agent told him that they will need to run her credit report because they’re still married. He told her that her credit will take a hit, but by the time she tries to buy a home for herself, it should be ok. Can they do that??? She didn’t authorize them to do that. They are divorcing. Please tell me she can fight him on this.
