If you need to get out of the marriage, do not let worries like this prevent you from filing for divorce. Early in the divorce process, the judge normally issues temporary orders which require the parties to maintain the status quo regarding bank accounts, credit cards, etc. This way neither party can freeze the other out of the joint finances or gain an edge by selling a car or home or making a major purchase. The judge can also make temporary orders for child custody and spousal support and topics such as who can use the family home while the divorce is pending. Share your concerns with your family law attorney to make sure the appropriate court orders get put in place.
