A client wishes to correct an error in a loan agreement dated 10.05.2024 by executing a supplementary agreement with retrospective effect. Experts suggest that an amendment, rather than a supplementary agreement, can be executed to apply from the original date, provided it's mentioned in the recitals. If the original agreement was a registered deed, a registered rectification deed might be necessary. The discussion also touches upon terminating a license agreement and seeking possession of property.
