No claims of any kind can be raised after a divorce has been finalized. All claims must be raised or preserved prior to the divorce decree being signed by a judge. Litigation after divorce is typically limited to enforcement of court orders entered during the divorce case that divided assets and debts and/or awarded alimony.
I'm in agreement with the first response you received;I would only add to the list of legal issues that survive entry of a divorce decree are those concerning children of the marriage. Custody and support are always subject to supervision/change by the Court.
I'm licensed in California so of course responses by attorneys licensed in your state would be more astute. Generally, unless waived or otherwise agreed to or adjudicated, support issues remain for a period of time depending on the facts of your case. Did you have a lawyer at the time? If you did, call your lawyer. If you didn't, call your lawyer. Whether the divorce was uncontested doesn't really answer the question as to whether alimony is appropriate and necessary in your case.
