Making the decision to divorce may be one of the most stressful experiences of your life. It's common for such a decision to spark many lifestyle changes and challenges, especially regarding your children, if you're a parent. Many issues stem from child-related matters, such as those involving finances, selling or keeping your Maryland home, school issues, custody and other topics. If you're one of many parents who believe you should have sole custody of your kids, the court will expect you to have good reason.
If your ex is an unfit parent, you'll need to show evidence of this to convince a judge or jury that your kids are better off in your care only. Past marital problems are not necessarily relevant material as far as proving a parent unfit. The judge is likely not interested in the fact that your spouse never cleaned up after himself or herself, or never appreciated you. Such issues may indeed have been factors toward divorce but don't necessarily mean your ex shouldn't share custody.
