Montana Title 1. General Laws and Definitions § 1-4-202. Manner of making a seal

The seal of a court or public officer, when required by law to be affixed to any instrument, may be affixed by a stamp or impression of the seal upon the paper, or other material on which such instrument is written, alone or upon any substance attached to the paper or other material capable of receiving a visible stamp or impression. The seal of a private person may be made in like manner, by the scroll of a pen, or by writing the word “seal” against the signature of the writer.
