Yes there are. These include direct negotiation between the parties, assisted negotiation by family lawyers, mediation, family law mediation followed by arbitration or resolution using the Collaborative Family Law process.

Very often when people come into my office they have already met with their spouse and have come to an agreement on many of these issues and they have jotted their agreement down on a piece of paper in point form. A family law lawyer can take these points of agreement and put them in the proper legal language and incorporate these into a Separation Agreement.
