Typically husbands and wives are responsible for each other's medical costs under the "Doctrine of Necessities" (also known as the "Doctrine of Necessaries"). That means it's unlikely those collections will be removed from your credit history on the basis of your dispute. You probably owe the bills just as surely as he does.
In California, spouses are jointly responsible for each others debts and obligations (if incurred during marriage). if the medical bills were incurred during marriage then you are responsible for them. If, on the other hand, you husband incurred the medical bills before you were married, then you should be able to get them removed.
