Equitable Distribution

In ED, does 401 K contributions or loss of rate count after the DOS? My stbx wants half of what I have contributed to date not from DOS.

Retirement accounts are divided using the value at date of separation plus or minus any passive increases or decreases in value (market fluctuations, not contributions or withdraws)

If i were to change jobs (possibly start own buisness) before ED and alimony are settled and divorced in which I may earn more or less, can my ex collect on any additonal money that I make from the DOS?

No, anything earned or owned after DOS is separate property.
