You are actually not entitled to any of his retirement.
Allow me to explain.
The law concerning retirement and divorce merely grants the state the right, in a divorce, to grant you up to half of the retirement based on any formula or method that the state sees fit.
That is as much guidance as the law gives.
So, you certainly are entitled to have the state consider you for 50%, but there is no automatic entitlement. You are not entitled until a court says that you get something and then you are only entitled to the degree that state court says.
As for SBP, unless a divorce court orders that you get it and you properly apply with DFAS and send them the decree within one year of the divorce, you don't get SBP.
Once your divorce is final, if you do not have that specific requirement in your decree, the SBP automatically stops or is shifted to someone else.
You must take the step, if it is in your divorce decree, to call DFAS and send them to the decree yourself.
If you husband did cancel the SBP, it can be reinstated based on the divorce decree.
If he remarries now, it won't have any effect on changing what the divorce decree says.
If the divorce decree names you the SBP beneficiary, then you get it and not the new wife (assuming you filed it with DFAS within a year after the divorce).
Your social security options are not effected at all by military law. You apply when you reach the right age.
That is a good resource to give your attorney.
