A promissory note could become invalid if: It isn't signed by both parties. The note violates laws. One party tries to change the terms of the agreement without notifying the other party.
Unlike a deed of trust or mortgage, the promissory note is typically not recorded in the county land records (except in a few states like Florida). Instead, the lender holds on to this document until the amount borrowed is repaid.
Different states have unique laws on whether a promissory note must be notarized. In New York, notarization isn't mandated for promissory notes to be enforceable. However, in California, while not explicitly required by law, notarization adds an extra layer of protection and legitimacy.
Promissory notes are legally binding contracts that can hold up in court if the terms of borrowing and repayment are signed and follow applicable laws.
Clearly outline the actions that will be taken in case of default, such as late fees, penalties, or legal recourse. Indicate the jurisdiction or state laws that will govern the promissory note. Both the borrower and lender should sign and date the promissory note to acknowledge their agreement to the terms.
Promissory notes are quite simple and can be prepared by anyone. They do not need to be prepared by a lawyer or be notarized. It isn't even particularly significant whether a promissory note is handwritten or typed and printed.
