You have several issues referenced in your question.If you are “legally separated” (meaning you have been issued a Decree of Separate Maintenance from the Family Court), then none of the financial issues addressed in that Order will be changed by any adultery at this point.However, you can file for an order of separate support and maintenance as soon as you are living apart from each other.South Carolina law is strict about the requirement that the husband and wife must be continuously separated for one full year before filing.The best advice that you would get from your Raleigh divorce lawyer is simple—don’t do it.

The confusion is often because a couple can be separated (and you must be to get a no-fault divorce).
In a nutshell, there is a difference between your living situation and your marital status: you can live separate from your spouse, but you are still legally married.
