While Iu2019m not an attorney, Iu2019m married to retired 1st Sgt of the US Marine Corps whose former spouse receives a portion of his military retirement/retainer pay (MRP). As such, Iu2019ll answer based on my knowledge of the Uniformed Service Former Spouse Protection Act (USFSPA).Under USFSPA, a former spouse (FS) is entitled to a portion of a service memberu2019s (SM) retirement pay regardless of the length of the marriage. For a FS to receive payments directly from the Defense Finance & Accounting Services vs from the SM, the couple must have a minimum 10 years of marriage with 10 years overlapping creditable service by the SM (i.e., the 10/10 rule). FSu2019s who were married to a SM for 20 years or more, with at least 20 years of overlapping creditable service by the SM, are entitled to the SMu2019s MRP, as well as lifetime healthcare coverage, base & commissary access.Entitlement by a FS to a SMu2019s MRP must be awarded by a court of proper jurisdiction. Without jurisdiction over the SMu2019s MRP, the SMu2019s MRP is not & cannot be considered divisible property. As such, if the FS in question has a final divorce decree/marriage settlement agreement that has already been accepted by the Court & signed by all relevant parties & does not include proper language required by DFAS that: A) Indicates the Court where the divorce was filed has properly obtained jurisdiction (i.e., the right to divide the SMu2019s MRP) & B) Awards the FS a portion of the SMu2019s MRP, not to exceed 50%, then the FS has no entitlement to a SMu2019s MRP.The only chance the FS has at obtaining any entitlement to the SMu2019s MRP, is to appeal the final/approved/signed divorce decree/marriage settlement agreement. Amending, or contesting a final divorce decree is nothing short of an uphill battle & demands the knowledge & expertise of a seasoned family law attorney who is well in matters surrounding the USFSPA. Unless the FS was forced to sign the final decree under duress (as in gun to their head, duress), without a good attorney & a hefty chunk of change to pay for said attorney, itu2019s unlikely a Judge will allow for any amendment to the existing final decree.Let us know what happens. Thanks!
