It is very common in a divorce setting to have Restraining Orders in place. Restraining Orders can come in many forms and have many appropriate uses.
One common use for a Restraining Order is to prevent your spouse from depleting assets while going through a divorce. A Restraining Order can prevent actions such as taking money from joint accounts, making withdrawals from retirement or investment accounts and running up significant debt/credit while the divorce is pending.
Another use for a Restraining Order goes beyond purely financial restraints and can speak to the actions or behavior of either spouse. It may be necessary to seek a Restraining Order when there is a need to limit contact between the parties or prevent inappropriate behavior around your children.
