Mediation is probably the best place to decide on how to divide your assets and/or debt.
It’s of course OK to discuss what is important to you in dividing the assets of the marriage prior to Mediation. But before determining a plan of asset division, it is important that you understand the difference between what is marital property and what is separate property. Hearing an explanation from your Mediator of marital interest in a retirement plan, pensions, or business(s) may cause you to change your mind about any pre-mediation plan you may have worked out. So it is best to start with a clean slate in the Mediation session.
