What Is An Affidavit Of Spousal Health Insurance? 
An affidavit of spousal health insurance is a legal document that may be required by an employer or governmental health plan -LRB- such as a state 's Children 's Health Insurance Plan or CHIP -RRB- that documents if the employee or applicant 's spouse is employed and if they are eligible for or covered by their employer 's group health insurance plan . This form will be used to determine if the spouse is eligible for enrollment or determine that their employer 's plan will pay in a primary capacity -LRB- pays the claim first -RRB- and the other employer 's plan or the government based health plan will pay in a secondary capacity -LRB- paying on any unpaid balance after the primary insurance carrier has paid on a claim -RRB- . Expect to see these types of forms in your workplace or if you or a family member are accessing public health insurance programs . Increasing numbers of employers , both private sector and public sector , are making efforts to move dependent spouses who have access to health insurance elsewhere off of their plans and onto the spouse 's employer 's plan . Increasingly an additional premium penalty is being applied to employees who insist on covering a spouse who has coverage available through another employer or source . And , in the more extreme circumstances some employers are declining to cover spouses at all . These actions are a result of the increasing costs of health care that employers and governmental agencies are experiencing and to a quirk in the Affordable Care Act -LRB- ObamaCare -RRB- that does not define a spouse as a dependent . Unfortunately , this is what happens when politician 's pass a law without reading it as was the case with the 2010 passage of the Affordable Care Act .
