It is not required that you hire a lawyer to get a divorce. If you and your spouse communicate well and are not disagreeing on major topics, you can get a divorce without a lawyer. If you do not have children and minimal assets, it is even easier. You can complete a divorce worksheet together to decide on how assets and debts will be divided. You may also benefit from working with a mediator, which are much more affordable than lawyers.
If you and your spouse are disagreeing on major topics such as child custody and division of large assets, you may benefit from hiring a lawyer. A lawyer can also help you discover assets and debts you may not have been aware of, which can be greatly beneficial if spouses have large variances in income and assets.
