If a soldier is not legally separated from their spouse, and she is living with another married soldier, do you still have to pay them BAH?

I'd be getting a REALLY good divorce lawyer. But seriously, contact your JAG office about this one

its two separate issues.
if still legally married you have legal obligations....do not quit those because its "unfair'. ask JAG, they are the experts in mil law.

the other issue, is best left to your lawyer, her chain of command and perhaps the IG
remember cohabitation is not a violation , adultery is.. but one does not prove the other.

This is a question for JAG I would not take advice about this from this site go see your local JAG tomorrow morning.

As long as you are legally married, you're still entitled BAH with dependents.

SGT (Join to see) define "you". If it is the government. Yes the Soldier still gets the BAH. If asking if the Soldier needs to pay for the roof over the wife's head. Well you are receiving BAH to pay for living quarters for spouse and yourself. Contact the lawyer to see if paying rent for a place that was meant for both is good enough or if you are required to provide rent to the spouse as well.

If a married Soldier has another married Soldier's wife staying with them this seems like something the chain of command might need to get involved with due to perception, particularly if they are in fact the husband and wife are not just putting that wife up in an extra bedroom while they get divorced. That could hurt the other Soldier's career. Either way is a mess and needs to be sorted out the sooner the better.

Sounds like adultery...

Sounds like someone needs to be reported for adultery.

Well if you're not legally separated, that's called adultery. Plain and simple. Military doesn't have those grey areas that civilians might have. In fact, that other soldier could be brought up on charges for sleeping with another man's wife. In regards to BAH, you shouldn't have to. BAH is for housing. You have a house. If she doesn't want to sleep under that roof, then she should be milking the BAH out of her new lover who seriously should be brought up on charges.

More details would be needed to make such a decision. The BAH is intended for living quarters for married soldiers who cannot bring a spouse into the barracks as a residence. (There may be an extreme exception) It is not specific to a person. When this question came up back in the dark ages, a soldier might be moved back to the barracks and the BAH continue to pay for the residence until legal issues are resolved.

I should think not. But I don't know if not legally separated it may remain a question however, I think it should be the right of the active military member as to wether to make the pay,ent or at least have the decision adjucated by the command in tandem with the legally married couple
