Thanks for the chance to help. I am an attorney with over 12 years military law
Ma'am I am sorry to have to bear bad news.
The DEERS (Defense Enrollment Eligibility Reporting System) office can, and likely will, require him to sign.
He is the sponsor.
Is it possible you can get a local DEERS office to bypass this (his signature)?
I have never seen it....but I will not say it is impossible. It may be you could convince the local office to ignore this signature requirement.
But there is no provision for this in the regulations that controls and requires the signature.
The better way may be to try and obtain some leverage to force this
If you went to court, the state court can order him to sign the form (to get you insurance). This is easy...of course you have to pay for this (in the form of a lawyer to file the motion with the court)
But so would he...he would have to hire a lawyer to fight it...and it is a looser fight for him (the court will order this since there is no cost to him and a huge benefit for you)
So perhaps if he understands you will go to court to force this, he will back down
But is there a provision that allows DEERS to ignore is failure to sign? No...in fact he rule is he must sign.
