CA Agents: Do All Offers Require a Contingency Removal?

[Jim Witten]

With standard CAR Forms....I'm trying to understand what establishes a buyer contingency on the buyers purchase offer? Is it simply Line 14.b as seen in the screenshot below, that's it?

Do purchase offers always require a CONTINGENCY REMOVAL form to be signed by the buyer after the X amount of days are up in line 14.b?
