When no consideration is given for an assignment,creditors of the assignor may have the assignment rescinded on the grounds that it violates the equal dignities rule.

The equal dignities rule pertains to the requirement that if an original contract was required to be in writing, then any assignment of that contract must also be in writing. It does not relate to the consideration given for an assignment or the rights of creditors to have an assignment rescinded. The issue of rescinding an assignment due to lack of consideration would more directly relate to the principles of contract law, specifically the requirement of consideration for a contract to be valid, rather than the equal dignities rule.
