In North Dakota the law of mortgages is mainly governed by state statutory and common law. Mortgagees are regulated by federal or state law or agencies.

• In North Dakota Execution of Assignment or Satisfaction must be signed by the owner of the mortgage.
  
  
• An assignment of mortgage must be in writing and recorded.
  
  
• Within sixty days after any mortgage is satisfied, or within thirty days of receipt of a written demand of the owner of the property, whichever is shorter, the owners of the mortgage or other lien shall execute a certificate of discharge duly acknowledged, and cause a satisfaction of record to be entered.
  
  
• Any mortgagee or owner of a mortgage or lien who fails to execute or deliver a discharge or to enter a satisfaction is liable to the owner of the property for all damages sustained, as a result of the refusal and exemplary damages of one hundred dollars.
  
  
• An assignment or satisfaction must contain a proper north Dakota acknowledgment, or other acknowledgment approved by Statute.
