Brothers in Christ’s should not bring their disputes into secular courts for unsaved judges to decide for them. Christians need to resolve their disgreements in the church first:
Do you not know that we will judge angels? How much more the things of this life! 4 Therefore, if you have disputes about such matters, do you ask for a ruling from those whose way of life is scorned in the church? 5 I say this to shame you. Is it possible that there is nobody among you wise enough to judge a dispute between believers? 6 But instead, one brother takes another to court—and this in front of unbelievers! (I Corinthians 6:3-6 NIV).
Christians have the ability and authority to judge between each other’s problems with love, patience, gentleness, and justice, if only they take the time and effort to do so. God will grant grace to us to judge our problems if we humbly submit to each other. We should settle our differences peacefully, and not disgrace the name of Christ by bringing them into secular court. I am not saying that we should ignore the court system/legal processes. There are certainly legitimate uses for the court system, and we should make sure that we are observing manmade laws in our financial dealings with each other. But we should not bring our arguments into court: we should act in unity with each other when we use the legal system to formalize our agreements. We should not display hatred and distrust for each other in court-room, but love and cooperation, and submission. We should display peace not only towards each other, but towards the secular authorities.
