pension entitlement v cash now

why cant i get straight advice from my lawyer, can i ask for honest help. i have a problem that i need to solve. is there a formula for working out the following problem/ my ex wife will be entitled to 36k of a balancing payment which her lawyer wants to take from my share of the house capital when we sell the house. my dilema is that this will leave me very short in the short to medium term when i come to buy a new house on my own. i would much prefer to keep the capital and give my ex a share of my pension. she on the other hand is concerned that the share of the pension will pay out a relatively small sum and would rather have the cash now. my point is this. is there a formula to work out the cash value now of from a future pension right. i am just looking for a straight answer as i feel the two lawyers are causing undue stress.my lawyer has offered 20k now and her lawyers starting position is 36k now....obviously somewhere in the middle is fair but how do i work it out in an objective manner

I think the answer is there isnt a formula or way of comparing cash with a pension share.

A pension is a future promise and as there is no way of knowing what impact the ecomony might have on pension payouts.
