You are not required to have a DC Separation Agreement. However, it is a good idea to have one if you have any issues that remain unresolved with your spouse.
What is a Separation Agreement?
A DC Separation Agreement sometimes called a Property Settlement Agreement or Marital Settlement Agreement is a written contract that protects you and helps make sure that your spouse lives up to his or her obligations that are outlined in the agreement.
An agreement will clearly spell out the benefits you are entitled to and the obligations you have.
