Alexis is right. You would need the paperwork to prove the divorce or wait until the next enrollment period.
If you have a special election period which is a qualifying life event such as losing coverage because you are coming off your husbands or getting a divorce in general, you have the ability to sign up for your coverage at work.
i never knew there wasn’t a way to get insurance after ‘open enrollment’, but maybe it depends on the job. if you’re concerned because you want to prepare, i would talk to HR. otherwise you can always go on state insurance until you are able to enroll/after the separation & then switch over.
Yes, divorce would be a qualifying life event that entitles you for a special enrollment. You'll just need the divorce decree so the divorce has to be final to switch.
You need a “qualifying life changing” event to be able to enroll anytime other than open enrollment.
