Clear, concise agreements are the safest. Lawyers refer to this as "offer and acceptance," or the act of one person making an offer and the other person accepting that offer. A lack of writing. Legally binding contracts are contractual agreements that are considered valid under both federal and state contract law.
For example: If Catherine Thomas does not complete the services of copy editing a page manuscript for Jones Publishing by July 15,this contract is no longer valid.
A contract becomes effective on the day the last party signs it. That said, certain contracts do require a written agreement, such as sales of intellectual property, shares, or land. Double-check with the other party, if necessary, to ensure both parties are in agreement about the specific nature of a particular deal.
