First refusal is a term used in real estate and business transactions that means having the right to accept or decline an offer before it is made available to others. When this right is exercised, a new offer has to be made to the parties involved in the transaction. However, there are several synonyms for this term, including "pre-emptive right," "right of first offer," and "right of first negotiation." These phrases convey the same meaning as "first refusal," and their use depends on the context of the transaction. In essence, these synonyms provide clarity and simplified communication between parties involved by ensuring that they understand the terms of the agreement.
