Statutes that are enacted to protect the public are called licensing statutes. Generally, unlicensed persons cannot recover payment for services when they do not have the required license. Problems arise if an unlicensed person tries to collect payment for services provided to another under a contract. Some statutes expressly provide that unlicensed persons cannot enforce contracts to provide these services. If a statute is silent on this point, enforcement depends on whether it is a(n) statute or a revenue-raising statute.

Explanation:

Regulatory statues are those that deal with procedures related to federal, state, and local governmental agencies. Examples of the procedures dealt in such scenarios are applications for licenses or administration for social services such as subsidized housing, health care or welfare just to mention a few.

Regulatory statutes give the advantage to unlicensed people to be eligible to enforce payments for contracts in the case the written agreement does not specify any provision explicitly.
