Pending a final judgment in an action for divorce, the judge presiding may grant as temporary child support a sum sufficient for the support of the children of the parties in accordance with Code Section 19-6-15. The judge may also hear and determine who shall be entitled to the care and custody of the children until the final judgment in the case. If a sum is awarded for the support of the children, the party who is required to pay the support shall not be liable to third persons for necessaries
furnished to the children.
