You are most welcome..my pleasure entirely!Thank you

It makes my day to know that my answer has been helpful to you.
I'm very happy to answer your further question with no additional charge whatsoever.
To read the actual statutory text (good bedtime reading!) please just click here:10 U.S.C. § 1450
Actually, it's not that lengthy (compared to some provisions, at least).
Now, here's the bad news. The arrangement you've described is quite common. However, nothing in federal law formally recognizes it. For a rough analogy, consider that very commonly a State Court, in a Final Divorce Decree, will divide assets and debts, including deeming one spouse entirely liable for a given debt (say a credit card). However, the creditors are not bound thereby and will continue collection efforts even against that spouse as long as they are/were an account holder.
This information sheet probably does a better job of explaining it:Former-Spouse SBP Coverage
Hope all goes smoothly...have a great weekend!
