What if some one filed no fault and spouse disagrees

If you are still involved with your spouse, some judges will not grant a divorce because there seems to be a reasonable expectation that you will reconcile. (You may have already reconciled if you're having sex with him.) However, the best way to protect yourself is to obtain an attorney, especially since your husband has legal counsel. If you do not have a lawyer and your husband (and his lawyer) try to get you to agree to something, you will not have the benefit of someone looking out for your best interest.
