It is important to know what community property the spouses have because in a dissolution case the court is required by law to divide the community property in a fair (not necessarily equal) way. You must be able to show the court adequate proof of what you are claiming as your separate property, as the court must decide which property is separate property belonging to each spouse. If a retirement plan is involved, the court may have to sign a special order (a “Qualified Domestic Relations Order”) so the company that keeps the retirement account can divide the money/benefits acquired during the marriage properly between the spouses.
