Legal Action Between Christians

Last night, our church had a discussion about a sale of land to a local Christian school. Essentially, the issue came down to whether the school had offered us a fair price, and many felt it had not. A vote was held which was inconclusive - there were too few members attending to come to a binding result. Nothing here yet to warrant a post to the Blog. But during the discussion it was revealed that the land - which adjoins the school already - had "uncertain boundaries" and thus "legal action" would be required to clarify the boundaries if we were to explore selling to other buyers. To non-Christians, this may seem like a harmless aside with no bearing on the issue. But Christians who have read the gospels will be aware that this raises a question that Jesus spoke directly upon.

Settle matters quickly with your adversary who is taking you to court. Do it while you are still with him on the way, or he may hand you over to the judge, and the judge may hand you over to the officer, and you may be thrown into prison.
Matthew 5:25

And it is further discussed by Paul.

If any of you has a dispute with another, dare he take it before the ungodly for judgment instead of before the saints? Do you not know that the saints will judge the world? And if you are to judge the world, are you not competent to judge trivial cases? Do you not know that we will judge angels? How much more the things of this life! Therefore, if you have disputes about such matters, appoint as judges even men of little account in the church![a] I say this to shame you. Is it possible that there is nobody among you wise enough to judge a dispute between believers? But instead, one brother goes to law against another—and this in front of unbelievers!
The very fact that you have lawsuits among you means you have been completely defeated already. Why not rather be wronged? Why not rather be cheated? 8Instead, you yourselves cheat and do wrong, and you do this to your brothers.
1 Corinthians 2:1-8

These passages are generally taken to mean that lawsuits between believers (and presumably between bodies of believers) should be avoided at all costs.

But what about "legal actions"? The bringing up of this issue before the Congregation was obviously intended to raise the specter of lawsuits, thus to encourage the Congregation to vote to sell the property. (Though it was never raised directly, to the credit of the Moderator.) I am curious as to the opinion of the readers of this site. Would a "legal action" like this - which would definitely involve lawyers, but likely no judge or arbitrator - be grouped under these passages? Are lawyers themselves to be avoided in discussions between Christians? Or are there times when it is appropriate to have "friends of the court" to assist in dispute resolution?

Do not assume this is idle speculation or philosophizing. The decision of our church may well wind up hinging on these verses.
