Ludwig's WRAP-UP
In summary, "as per prior" is a prepositional phrase used to indicate that something is being done or stated in accordance with a previously established agreement, rule, or communication. Ludwig confirms that the phrase is usable in written English. It is most commonly found in scientific and formal contexts, signaling adherence to documented agreements. When writing, it is best to use "as per prior" in formal contexts where referencing a clear and previously agreed-upon guideline is necessary. In more casual settings, simpler and more direct phrasing is often preferred. Though grammatically correct, overuse in informal contexts can be perceived as overly formal.
