I viewed it once and did not answer. The Real Estate Commission of each state provides the forms for Realtors. You can get them free from your State’s web site. Also title companies will provide you with forms.
The assignment form is pretty much just a one line agreement and signed by the buyer and you.
I hereby assign the earnest money contract between __________ and _________ dated _______ concerning the property located at _______ to _______ for _________ to be paid at closing or ______ and ______ at closing.
Buyer hereby assumes all duties and obligations under said contract.
There is not much else to it. Your title company mat have one they like to use as well
