The rules for collecting a spouse's social security benefits are pretty straightforward regarding divorce and remarriage. The total length of the marriage is the key.
Social Security Rules Regarding Divorce and Remarriage
Please read our article regarding remarriage and Social Security benefits for spouses. You will find a list of criteria that may apply to this situation. For example, it is possible for a wife to qualify for her first husband’s benefits after a divorce and brief remarriage if they were married for at least a total of 10 years. However, she may not qualify for the second husband’s benefits because the length of the marriage was too short.
If the criteria seem a bit confusing, get more specific advice by contacting an attorney in your area to help determine eligibility and file for benefits.
