Probably one of the most frequent problems I encounter with new cases clients bring to my office is the lack of documentary evidence.
No one bothers to put down in writing that agreement with the brother-in-law or “friend” about the business they were starting together, the house one was going to buy (by signing on the mortgage) and which the other was going to “own” (by going on the title) and paying the mortgage, the investment they were going to make together, or any other manner of legal arrangements.
Then, when things “go south” and the “owner” does not pay the mortgage or the business fails (or even prospers, in which case you will see fights over profits), the differences in each person’s understanding of what was agreed becomes painfully obvious.
But what’s worse is that the prospective client has nothing in writing to back up his side of the story. It becomes a “he said / she said” dispute hard to win in court. Convincing a judge or jury of the rightness of your position is now just a coin flip.
