Grandfather Clause


In finance, a Grandfather Clause refers to an exception that allows an old rule to continue to apply to some existing situations, while a new rule will apply to all future situations. Normally, it is used to exempt certain entities from following a new regulation or law. The purpose is to avoid disruption or hardship created by the sudden change of rules.


The phonetic transcription of ‘Grandfather Clause’ is: /ˈɡræn(d)fɑːðər klɔːz/.

Key Takeaways

  1. The “Grandfather Clause” was a post-Civil War legal tactic employed by Southern states in an effort to deny African Americans their voting rights. It stated that men could only vote if their grandfathers had the right to vote. This directly targeted African Americans, as the grandfathers of many were enslaved and did not have that right.
  2. The Grandfather Clause was an example of systemic and legal racism prevalent in the United States for much of its history. It effectively maintained a racial hierarchy by ensuring that the majority of African Americans remained disenfranchised even after the 15th Amendment granted them the right to vote.
  3. The Grandfather Clause was ultimately deemed unconstitutional by the U.S. Supreme Court in the case of Guinn v. United States in 1915. This was a crucial step in ending some official forms of racial discrimination, though many forms of voter suppression were still implemented thereafter.


The term “Grandfather Clause” plays a significant role in the field of business and finance, primarily because it helps to preserve stability and predictability during times of regulatory or policy transition. The clause refers to exceptions that allow existing entities or individuals to continue operating under pre-existing rules even after new regulations or laws are passed. This is particularly significant in business as it provides a cushion for companies, preventing them from being immediately affected by sudden legal changes, thus granting time to adjust and transition smoothly in compliance with the new rules. Such a clause can often prove crucial in avoiding potential negative impacts on businesses’ operations, financial positions or strategies, and hence, is considered highly important in the business/finance world.


The primary purpose of a Grandfather Clause in the realm of finance and business is to exempt certain entities from new rules or regulations that may adversely affect their operations. It essentially serves as a measure of protection for businesses, corporations, or individuals who were in operation or existence prior to the implementation of these new laws. Grandfather clauses are created with the intention of preventing potential disruption or losses that these entities may experience, due to sudden changes in law that might affect their normal routine or functioning. It cushions these entities from the effect of the law while still allowing the new law to be enforced on future entities or transactions.To illustrate, if changes are made to a financial regulatory framework, companies that fall under this regulatory environment would usually have to comply with the new rules. However, those protected by the grandfather clause could continue to operate under the old regulations, which is often to their advantage. Similarly, for individuals, if tax laws change to be more stringent, a grandfather clause might protect those who were already in the system under the older, less stringent laws. Thus, grandfather clauses play a crucial role in ensuring a smooth transition during times of regulatory changes by minimizing disruption for those already within the system.


1) Real Estate Zoning Laws: The term “Grandfather Clause” is often used in the context of zoning laws, where a business or property use that is considered nonconforming under current law is allowed to continue because it was established before the new law came into effect. For example, a local town may have established new zoning laws restricting commercial businesses in a certain residential area. However, if there were a convenience store already running in that area before the law was implemented, it would be “grandfathered” in—allowed to operate despite the new rules.2) Environmental Regulations: Grandfather clauses also appear in environmental laws and regulations. For instance, when the United States Environmental Protection Agency puts forth new emission standards, it often exempts existing facilities or sources of pollution, allowing them to continue their current practices while requiring any new facilities to comply with the new standards. 3) Telecommunications: The Telecommunications Act of 1996 granted a “grandfather clause” to radio and television stations—the deregulation allowed companies to own a significant number of stations, but those who already owned more than the newly specified limit in a single market were allowed to keep them, as they were “grandfathered”. The purpose was to promote competition by preventing media monopolies, but it did not apply retroactively.
