Ask ACE: Do all agreements need to be in writing now?

Q: I believe that if you expect trust, you should show trust. I used to be able to do business on a handshake, and rarely got burned. Do all agreements need to be in writing now?

ACE advises: Verbal agreements may be enforced. Some agreements must be in writing. We’ll identify those. The real question is not whether agreements must be in writing, but whether they should.

History lesson: The handshake deal sustained a body blow in 1677. When literacy rates were below 20%, English courts decided contract disputes based on witness testimony alone. After a few centuries it was obvious the “they said, they said” approach had problems.

Both sides’ witnesses might be believable, making judgment a coin toss. This was particularly unfair when that coin toss came at high cost to the loser or gave the winner an undeserved windfall.

It was never about trust; it was about better proof. With rising literacy, Parliament decided that certain contracts were so lucrative that witnesses would be tempted to lie or could result in unfair financial injury if the court got it wrong. Enacted in 1677, the statute of frauds required written proof of agreements to:

  • Require an executor to pay an estate’s debt personally
  • Guarantee a debt
  • Pay for a spouse
  • Transfer a real estate interest
  • Perform the contract for more than a year.

Today, all 50 states have statutes of frauds, roughly based on the original. Almost all require written proof of a sale of goods worth more than a certain amount (usually $500). In addition to the original five categories, Maine requires written proof of contracts to pay a debt discharged in bankruptcy, give property by will and not to compete.

You can memorize these categories, or just document your agreements. The U.S. literacy rate is 80%. Statutes of fraud simply require “a writing.” An email exchange may be enough to lay out the basic terms, and the other party’s acceptance.

More complicated deals may require a lawyer. But before you decide a handshake is enough, first decide how much you can afford to lose on a coin toss.
