A stupid question- will I get his retirement for the rest of my life (when the time comes) based on what he'll make in the future, raises, higher paying jobs, etc, or just on what he's made since we've been married?
Depends on what the court order says. If the court order says that you will get a percentage of his retirements in the future without specifically stating that it is limited to the value of what the contribution was during the marriage, then you will get a percentage of everything.
