In my divorce agreement (1-May-06) it specifically states I am not responsible for alimony or healthcare costs for my former spouse. I am soley responsible for providing information to my employer to enable my former spouse to be insured. She is financially independent from me in all respects except receiving child support. Previously, the company treated my former spouse as family and she was covered identically to me. This year the employer required me to define her as a "domestic partner" though I believe this a fraudulent definition. As "domestic partner" they attribute "imputed imcome" to me for a benefit which I do not receive, AND though I have no responsibility to provide health insurance to her in any way. Does the employer have a responsibility to allow my former spouse to be in the companies insurance group under MA law though I have no responsibility to provide or pay for her health coverage?
