I know my spouse has been hiding money or at least spending too much money up until the divorce was filed. Do I have to prove it?

Yes. However, it can be done in two ways. Bearden Investigative Agency, Inc. can either find the hidden funds or, if you can document the original existence of the money and the now missing funds, the court may simply assume that the funds were taken for use by your spouse and they will credit that amount as though they had given that amount to him. Very frankly, this sometimes results in a windfall for the victimized spouse particularly where the spouse hiding the money has not saved it. However, don't become confused. Either spouse of the marriage has the right to spend community property funds. It is only when they are overtly trying to hide them from the court that the court will take action. You may not have agreed with your spouse's expenditures, but unless it is egregious or there is a current tangible benefit accrued from the funds, (car, boat, etc.) the court is not likely to consider routine expenditures in division of the property.
