Is a surviving spouse in Illinois obligated to pay medical expenses incurred by the deceased spouse prior to death?

Yes, you are under the law married couples are considered one unit, that makes you responsible for eachother. * No. Not unless the surviving spouse signed an agreement to do so. The only time spouses are responsible for each others debts is if the debts are incurred jointly or the couple resided in a community property state, Illinois is not a community property state.
