Kelley, I'm really sorry you are going through such a rough time but as a twice married and divorced woman let me tell you that you are in for a lot of hard work and a rough road. First, if you have children don't leave them with your spouse because you could lose custody. Second, why should you leave the house? Your business and livelihood are based there? I hope you can work things out so that you can live a happy, peaceful life, but it will take time.

To answer your question, a month's notice for your clients if you are closing is generous. Hopefully, they will be very sympathetic to your problems.
