Getting a divorce in Denver means that you'll be working through an equitable-distribution case. What that means is that you'll be dividing your assets fairly, not evenly, upon your divorce.
As your child grows older, they may feel that they'd like to see some changes in their custody arrangements. For the most part, they cannot seek those changes on their own and will rely on you to ask for changes to custody through the court if the other parent won't agree outside court.
After you go through a divorce, there may be times when you want to make changes to your divorce decree. For example, if you accepted certain assets upon divorce but later discover that your ex-spouse hid assets, you and your attorney may petition the court to review what you've found.
When you're a parent who has to fight for custody of their child, you want to do everything you can to appear professional and respectful in court. Doing so makes you look like a better parent and encourages the court to give you what you want based on how you present yourself.
Sometimes, you don't want to go through the challenge of a divorce. In fact, you may dislike your spouse so much that you don't even want the record of your marriage to exist. That's what an annulment is for.
