I disagree with ArmyJudge's conclusion that your husband has any present ownership interest in the house. He doesn't. ArmyJudge is in a community property state and community property law functions significantly different than states that derive their property law from English law (community property law derives from Spanish Civil Law). Under community property law, a spouse gets a present property interest in most property obtained by either spouse during the marriage, known as a community property interest.
But under English property law, that is not the case. Non community property law states provide that a spouse may get a marital interest in property that his/her spouse gets during the marriage, as ArmyJudge noted for NC. But that marital interest doesn't give the spouse any present ownership interest in the property.
Put more plainly, unlike in community property states, your husband doesn't own any part of that house you bought. You could sell it tomorrow and not need his consent to do it. What the marital interest rules do is give him an interest in it at the time of divorce (if that ever happens). In short it's a rule applied in divorce proceedings. That is why the rule ArmyJudge quoted is in NC's statutes for divorce, not property law.
You can easily give him a share of the property via a quit claim deed. But you'll need for him and the lender to agree to add him to the mortgage (or refinance with your husband as co-borrower) for him to be legally liable for the mortgage payments. You won't want to give him that quit claim deed until he is also liable for that mortgage, too. Typically, you'd do that at the same time — he signs off on the mortgage and you sign off on the deed. I suggest you see a real estate attorney to get it right.
