Paying my ex-wife's health & car insurance

I’ve been paying my ex-wife’s health insurance through my employer for 5 months now. It is open enrollment for 2010 - do I have to include her on the policy? It costs me $145.00 per month to keep insuring her… I am also paying her car insurance through my employer can I also take her off this. If I can take her off my insurance what is the best way to tell her I am doing so. We do not have an agreement in place.

Legally you may remove her from the insurance, however many employers will not allow you to do so unless you are divorced, have an agreement, or can prove she is otherwise covered. Check with your HR to ensure you can remove her, if you can, be sure to notify her in writing of the need to secure her own coverage.
