Prior right purchase refers to a legal principle that gives a potential purchaser the right to buy a piece of property before anyone else. The term is often used in real estate, where it can give buyers an advantage if they have existing rights over the property. There are several synonyms for the term, including pre-emptive purchase, first-option purchase, right to buy, and preferential purchase. These terms all describe a similar concept in that they relate to the right of first refusal to purchase a property or asset. Regardless of the synonym used, the legal principle remains the same - providing certain individuals with the first choice to purchase.
