“Legally separated” can be a misnomer; in many cases, a legal separation and a divorce are the same process. Many people mistakenly call a signed Separation Agreement a “legal separation”, which is not entirely accurate.
If you and your spouse can agree to all of the terms of a Divorce and have no children from the marriage, the Separation Agreement and Divorce filing can be created simply and inexpensively using Standard Legal’s No-Fault Divorce legal forms software. But this option from Standard Legal is only for couples without minor-age children.
