I live with my fiance, can I get health insurance coverage through his.?

I am currently attending school and I live with my fiance. He works and has health insurance is it possible for me to also be covered under his health insurance policy?

Some insurance companies will cover significant others that are not married. My insurance through my employer will cover my significant other but I have to show proof that we have been living together for 3 years plus. What my insurance company requires is for him to show utility bills, car insurance or credit card statements that are coming directly to my house. The rates for adding a significant other are the same as if we were married. Luckily for me, we broke up after 3 years so now I don't have to pay extra premiums. Have your finacee check with his insurance company to see what their requirements are.
