Alimony / Post sep support

My husband whom I am separated from is entering the USAF as an officer. We have a separation agreement drafted, and will be signing soon. We have settled child custody at $1,600/month, alimony at $840 and post separation support (for 7 months only) at $160.

Alimony is permanent and PSS is temporary, right?

Correct, PSS refers to temporary support that will stay in place until alimony, which is permanent, begins. Keep in mind that while alimony is considered permanent that does not mean that it will continue indefinitely. Thera are certain statutory triggers that will end alimony, and most agreements will include an time limit for which a party can receive alimony.
