The term "hush money" is typically used to refer to money paid to someone to keep them quiet
Whether or not this type of payment is legal depends on the specific circumstances surrounding the payment and the applicable laws.
In some cases, hush money may be legal if it is paid as part of a legally binding settlement agreement
It is important to note that even if hush money is paid as part of a legally binding agreement, it may still be subject to disclosure requirements or other legal obligations.
