In a listing agreement: a. no handwritten instructions are allowed. b. handwritten instructions must exactly match preprinted instructions. c. preprinted instructions supersede handwritten instructions. d. handwritten instructions supersede preprinted instructions.

The correct option is D, handwritten instructions supersede printed instructions.

Explanation:

A listing agreement is a legally enforceable agreement between property owner and the estate agent or broker, wherein the agent is authorized to find the prospective buyer for the owner's property.

Handwritten instructions in this parlance, take precedence over pre-printed instructions as handwritten instructions are seen as a form of endorsement by the property due to the uniqueness of handwritten from one individual to another.

The handwritten of someone can be used to verify the authenticity of the information so written whereas preprinted information is generic.
