If the divorce has been finalized after many years, can either party re-marry now?

A case of divorce that began with affectionate separation 14 years ago and official legal separation 12 years ago concluded divorce officially this month. The divorce proceeding involved young children and a very contentious custody battle that lasted until all the children became adults. The divorce was final and officially completed this month, also concluding all child support and alimony orders. Would either party be able to marry again at any time now? The original date the respondent was served was 12 years ago. Some responses indicate they can re-marry at any time, others stress a six month period referring to the time the respondent party was served typically addressing re-marriage from filing date requiring six months. How soon can either individual legally marry again? Someone mentioned in some States there is a six month waiting period that intends to protect against unwanted or unknown pregnancy. Others mention either party can marry again at anytime in this case, especially after the official divorce has been officially finalized from original filing date. Clarity on the issue would be appreciated.
