No, actually I don't. Financial planners often encourage pre-stepfamily couples to get a "prenuptial agreement," but that just sounds like you're planning for a divorce. There's a much better way. A Togetherness Agreement helps blended family couples manage their daily expenses, discuss insurance and retirement, and do estate planning for their children and each other. It builds confidence in how to manage money in your complex family. Don't let money issues divide you; finance togetherness.
