But mediation doesn't necessarily solve every issue facing a separating couple. Until now that's usually meant that a judge has had to make the final call.
Family arbitration offers an alternative. Essentially it's an entirely confidential way of reaching a decision about your finances or your property if your relationship has come to an end, but without judicial intercession.
Like a judge, the arbitrator will make sure that all the relevant facts are gathered together. The arbitrator will also gather evidence from you and your partner.
They will take into account your views on what you think should happen. Then they give a ruling.
It can be done face-to-face or it can be done with a bit of distance between the parties. The couple chooses what suits them, just as they choose their own timetable so they can control the speed of the resolution in a flexible kind of way.
Because both partners will have agreed to stick to the decision, neither of them can back out without the other's agreement.
Thomas Stipanowich, a professor of law at Pepperdine University, in California, who has been in Auckland as a Law Foundation visiting fellow, believes the growing international popularity of family law arbitration reflects to some degree frustration with costs, delays, risks and limitations.
This has, he says, "prompted growing attention to informal methods aimed at early, efficient resolution of disputes that are client-controlled, co-operative, relational, informal, interest-based, flexible, early, expeditious and efficient".
