The acquired-rights doctrine is a legal principle that protects vested rights from being changed or diminished by new laws. Essentially, once a right is established, it cannot be altered by subsequent legislation. A notable example of this doctrine is seen in the Universal Copyright Convention, which safeguards copyright protections that were in place before the Convention was enacted.
This doctrine is commonly used in areas of law such as copyright, property rights, and contract law. It ensures that individuals or entities with established rights can rely on those rights without fear of them being undermined by future laws. Users can manage certain legal matters related to acquired rights through legal forms and templates available from US Legal Forms, which can help in drafting agreements or protecting existing rights.
Here are a couple of examples of abatement:
For instance, if a writer has obtained copyright for a book under a specific law, that copyright cannot be reduced or revoked by a new law that changes copyright terms. (Hypothetical example: A musician who registered their song before a new copyright law takes effect retains their original rights.)
Examples of state differences (not exhaustive):
| State | Variation |
|---|---|
| California | Strong protections for copyright under state law. |
| Texas | Less stringent on property rights changes. |
| New York | Robust protections for vested rights in contracts. |
This is not a complete list. State laws vary, and users should consult local rules for specific guidance.

| Retroactive Law | A law that applies to events that occurred before its enactment. | Acquired-rights doctrine prevents retroactive laws from affecting vested rights. |
