I feel like this is a trick question; I provide to my clients, 100% of the documents on (CAR) California Association of Realtors forms and my TC and I are sure to have all needed disclosures and forms completely filled out to clients' needs. Now I always have my clients fill out the TDS & SPQ themselves. (Transfer Disclosure Statement & Seller Property Questionnaire), so that I do not play any role in their answers. We often use CAR addendum's in counter offers and request for repairs, etc. We never work with forms from outdated or alternative sources in SOCAL. When I worked in Nor Cal, we had a second set of accepted forms produced by PRDS, which were more popular, but here in San Diego, CA, we use CAR forms as a standard.

We work with standard forms. 

Good luck with your studies.

Every state is a bit different, but basically fill in the blanks with the right stuff.

Filling in the blanks

We fill in the blanks on the state approved contract forms. We do the will of the client.

We use standard forms and draw up simple addenda but ask the client to consult with a lawyer for any special amendments.

we use Greater Boston Real Estate Board contracts.... attorneys make the changes....

Same, we work with a standard form of contract.  Here in our part of NJ we have Attorney Review where revisions/refinements can be made by the attorneys. The standard form captures the terms which are negotiated to reach an agreement.

jacquelene rivers We use standard approved forms, but often required to add an amendment or addendum to the offer.

I think you can use industry-standard unblocked gamez templates and draft only the most basic of addenda, recommending that our clients speak with legal counsel for more complex changes.

You have to know them inside and out, forwards and backwards and be able to explain them fully to your clients as you fill in the state-provided form blanks. Then you have them initial and sign so you can present to the other party's representative.
