Hiding assets is often a problem in a divorce. When a marriage begins to break apart people all react differently. If you have a partner that has a “Cluster B” personality disorder, such as narcissistic personality disorder, and they are in control of the assets, it is almost a foregone conclusion that they are going to hide money and assets and attempt to circumvent the process. If you are planning on divorcing a narcissist, beware! Unless your plan is carefully executed, you will be caught in the grip of a spouse who views anything you do as an attack and negotiation as simply another venue to manipulate, and in the family court, such people have a distinct advantage. Although you may believe honesty is the best policy, (as I do) it often does not help, and can hurt your future. Courts make decisions based upon appearances more than a careful review of the documentation. That assumes you are astute enough to gather the documentation and know what is important.
That being said, there is good news to be found in the informal provisions of the family code. Under Family Code Sections 1100, 1101, 2100, 2106, 2107, 721 your spouse has an affirmative duty to be forthcoming about assets and income. That means they MUST provide you the information about any community property asset and you do not need to ask. Failure to do so allows, and in some instances requires, the court to punish the wrongdoer. The king of all family law sanctions devices, Family Code 271, allows the court to punish the party who is attempting to circumvent the process.
