The technical answer is that you should receive half of that portion of the retirement that was earned from marriage to separation. In your case, separation should mean the final separation. It will be necessary to file amended dissolution paperwork with the new date of separation.
How you divide the pension depends on what kind of pension it is. If it is a traditional formula monthly pension, then you will get your percentage based on the amount of time you were married vs. his total time in the job that earned the pension.
So, if he was already working when you married, the time he put in before marriage is his and you don't share that. The time he puts in after separation is also his alone. You only get 1/2 of the part when he was working and you were married to him.
If he has a 401(a), 401(k), 403(b), 457, IRA or any other type of retirement (except Social Security) you get that, too.
Military pensions are different. If he is active duty military or reserve and that is the pension you are discussing, there are special rules that apply. Get a lawyer to help you, at least with this part. Even if it is a simple 401(k) and that's it, you can easily cheat yourself out of thousands if you don't know what you are doing and, trust me on this, almost no-one does.
