To reduce or cancel your SGLI, you must complete and file a form SGLV 8286, Servicemembers' Group Life Insurance Election and Certificate, with your uniformed service. If you reduce or cancel SGLI on the first day of duty, your election will be effective immediately. If you make an election after the first day of duty, it will be effective at the end of that current calendar month. If you are reducing or canceling part-time coverage, your election will be effective at the end of the last day of the period of duty you are serving. (For more detailed information, see the SGLI Handbook, 3.01 and 3.02.)Married Servicemembers should be aware that if they elect to cancel coverage their spouses will be notified by the Department of Defense of the election. In addition, if they reduce their coverage below the maximum amount, their spouses will be notified upon the first reduction of coverage and any subsequent reductions of coverage if those reductions result in less coverage than the initial reduction.
