How to Divide the Property?

My wife and I have been through quite a bit of marital issues over the past 22 years, and have finally decided to get separated. Now that our two children have moved out, we're ready to go our separate ways. We are not exactly on good terms, but we're not at each other’s throats anymore either. The main problem we are going to have is figuring out who gets to keep what property. Are there some alternatives that we can use to help reduce the cost of a divorce and still get a binding agreement made regarding the property division? – Frank
