I assume that you are fully vested? Unless CA is different than other states the PERS itself cannot be divided, so it would have to be offset by other assets. Basically she would be entitled to 1/2 of the amount contributed during the marriage, and any growth attributed to that 1/2.[/QUOTE]
With the current state of various retirment savings plans. one wonders: if a party contributes $6000 during the marriage, and what tat $6000 bought is presntly worth $4000, does one split $4000? If a spouse shares in the increase in value, should they not also share in any decrease in value that occurred DURING the marriage?
The correct amount is the present value of the amount contributed during marriage.
For example, during your marriage, you contributed $10 K. The current value of that $10 K is $15 K. You split the $15 K. If it drops to $5 K, that's the amount you split.
HOWEVER, this is pre-tax money. It is not correct to offset pre-tax money 1:1 with after tax money (although many attorneys and even some people who claim to be experts in financial planning do so). If you are supposed to split $20 K in PERS, then she is entitled to $10 K in PRE-TAX money. If you have other pre-tax assets to equalize with, use those. If you have to use after tax money, you need to adjust it downward since you've already paid taxes on the after tax money.
If you're in the 30% tax bracket (including state, Federal, and SSI taxes), then at the very simplest level, you'd give her $7 K in after tax money to offset $10 K in pretax money. Ideally, you'd have to do a more sophisticated calculation involving your current tax rate, her current tax rate, anticipated future tax rates, and so on and this involves a lot of guesses, as well, so it does come down to a guess, but any guess is better than a 1:1 offset - unless you think you're permanently in the 0% tax bracket, make sure you have an adjustment for taxes.
