What type of endorsement should Diana use to sign her check over to Kim for last month's rent?

Diana should use a special endorsement to sign her check over to Kim for last month's rent because a special endorsement allows her to specify the person to whom the check is made payable. By writing “Pay to the order of Kim” along with her signature, Diana effectively transfers the check to Kim, granting her the right to deposit or cash it. This type of endorsement is ideal for situations where the check is intended for a specific individual or entity.

In contrast, a blank endorsement simply involves the individual's signature on the back of the check, which makes it payable to anyone who possesses it, thus offering less control over who can cash or deposit the check. A restrictive endorsement places limitations on how the check can be used, such as requiring it to be deposited into a specific account, and may not be necessary in this case. A conditional endorsement indicates that the check's payment is subject to a specific condition being met, which is also not applicable here since Diana is directly transferring the check to Kim without such contingencies.
