The statute of frauds in various states comes in three types: Those that follow the English statute and provide that "no action shall be brought" on the contract or the contract "shall not be enforced", e.g. the Arizona statute in Title 44. Those that declare contracts "void". Those that make the contract "voidable" at the affected party's election. Colorado Colorado has a number of different statutes of frauds applicable to different areas of law. Texas In addition to the statute of frauds as conventionally defined, the State of Texas has two rules that govern the litigation process, each of which also has the character of a statute of frauds.

The Texas Government Code requires that "[a] contingent fee contract for legal services must be in writing and signed by the attorney and client." TEX. GOV'T CODE ANN. § 82.065(a).

The other scenario is a contingency fee contract based on cost savings achieved (for
