People who are going through a divorce likely have an idea of what they want to walk away with. However, this might not be realistic or what's best for them.
Once you come to terms with the fact that the marriage is over, it might be easier for you to think about the property division process because it may be less emotional than other aspects of the divorce. If you are walking away from a narcissist, it's especially important to know what you want because you are likely going to be facing a difficult journey.
A narcissist will try to manipulate situations to get their way. They aren't concerned about anything other than their selfish desires. They might try to appeal to your emotions, but they can also use methods like criticism or passive-aggressive behavior to try to gain control of the situation.
When you are dealing with a narcissist, there is a good chance that some alternatives to a trial might not work. It can be difficult or impossible to go through mediation because your spouse won't be willing to negotiate over matters like who is going to get which assets. This means that you will have to prepare for a trial.
One point to remember in these cases is that you need every agreement spelled out as completely as possible. The more details you have in the property division, child custody, and support orders, the better you are likely going to fare in the future. It takes the guesswork out of it and offers less room for misunderstanding and conflict.
