Is it legal for my separated husband to remove me from health insurance without my knowledge?
The title is essentially the question, but here's a little background & timeline:
My soon-to-be ex husband and I filed for divorce in September 2025.
In November 2025, I had a routine physical. When I was at the doctor's office, they were having trouble verifying my insurance via the information that I provided, and I said maybe I have the wrong number, the number from my old plan when I was taking insurance through my job instead of his. I thought they had resolved it but in early December-ish, I received a bill for over $300 for this routine annual visit.
Fast forward to March 2026, my attorney asked me if I was still on his plan or if I have gotten my own coverage (this was relevant to the financial affidavit process). I said I believe he has removed me from coverage, but I missed my open enrollment period so I will have to wait until the divorce is finalized to in order to get back on the coverage with my employer. They respond saying that he informed his attorney that he still has me on his coverage and will continue to do so until the divorce is finalized. I tell me attorney that, in that case, it is confusing that I received a $300+ bill for a physical. That was the end of the conversation.
Fast forward to today, May 2026, I was supposed to have a dentist appointment tomorrow morning. They ask me to confirm my appointment and to provide my insurance information to update their system. I tell them I will have to check and see if I have the card at home, and if not I will have to reschedule (to avoid another situation like my doctor's visit). They ask if I know which insurance company it is. I tell them the company and explain that it my husband's plan, we are separated, and I have no access to information online to look it up. Then they ask who is his employer. I tell them where he works. They are able to look it up for me and inform me that my coverage term ended on October 31, 2025.
So my question is, is he allowed to remove me from health insurance coverage without my knowledge or without discussion? Although there sort of was discussion, in March, when he said that I am still covered even though I'm now finding out that I actually was removed in October? But as of March he told his attorney that I am still covered? Not sure there is any action to take and it likely won't affect the divorce anyways, but I'm almost fuming that I have unknowingly been without health, dental, and vision insurance for over 6 months.
