Prenup and mediation

My wife and I are using a mediator to set up our separation agreement.
We also signed a pre-nup prior to our marriage.

Is the pre-nup still usable in in the mediation?

I’m not an attorney, but I would assume so as that was the purpose of the pre-nup.

Yes, the prenuptial agreement should be where you go to look for the terms to begin completing/negotiating the separation agreement.
