Agree with this they will 100% settle out of court. J must be seeking financial compensation as Lindsay essentially “took over” their company without any form of buy out.As a legal eagle, legal fees are expensive in this country. Most things settle out of the court financially in civil cases to a) save face and b) reduce solicitor's costs. Whether we actually hear about any of this or actually see the girls rocking up to the four courts is unlikely.
Defamation would have to be at a level where someone destroyed your character. J and L are both doing just fine in that regard. Likely it's just a business winding up issue and one side wants financial compensation.
Once you start suing a former friend it shows that your friendship was fairly transactional to begin with, but that is just my opinion.
