3 Having force, of binding force; legally sufficient or efficacious; authorized by law. Opposed, invalid: as, a valid or invalid — condition, consideration, defense, instrument, marriage, sale. Whence validity, invalidity, invalidate. A sale of land may be regular in form and in the mode of its conduct, but it cannot be "valid," unless authorized by law.* "Validity " is legal sufficiency, in contradistinction to mere regularity... A valid judgment, decree, or sale is not void for any reason. A valid sale means one having the quality of legal sufficiency and complete obligation.' That what is invalid in an instrument will not destroy what is valid, see Utile, etc., p.
