To be enforceable, a memorandum evidencing an oral contract must identify the consideration.

Memorandum

Oral Contract

An agreement between parties spoken and agreed to aloud rather than written, yet is legally binding.

Consideration

The benefit, interest, right, or profit involved in an agreement or contract, on which it is based.
