Negotiating a settlement agreement with your former partner that both of you can live with is likely to save you a lot of money, time and stress.
Settling will be quicker, easier, and cheaper and probably get you closer to what you want than a court decision.
If possible it is better to stay out of the courts.
If you and your partner are already in an agreement, lawyers can help you get settlements done in a legal way without going to court.
If you think you could reach an agreement but emotions are running high or there are a few things that you cannot figure out together, you may wish to consider mediation of hiring a a lawyer to help you find new ways to resolve the situation.
Even if you go to court, you can still decide to come to an agreement with your ex. This can be done in the middle of a trial if need be.
