You're welcome
It needn't be difficult if both parties are clear about a) what kind of pictures they want, b) what they want to do with them, and c) what they
don't want the other party to do with them without prior agreement (which may be refused of course).
You don't need complicated forms full of bewildering legalese. They might sound impressive but simple, clear language is rather better IMHO. A model release form actually has no official legal status - it's just a form of words and any form will do so long as it's clear and unambiguous.
Key points - the agreement needs to identify the photos specifically in terms of photographer, model, time and place. If nothing else is agreed, all rights belong to the photographer so the important bit for the model is to add something about what they are allowed to do with the images and if necessary specify what they don't want the photographer to do with them.
Ideally, none of this should be a problem for either side, bearing in mind that the whole idea of TFCD is mutual cooperation for mutual benefit. TBH if any of these things cause problems then maybe you need to think about doing things differently, with one party paying the other in return for whatever terms they need. It usually works quite smoothly though; run through it in the pre-shoot chat and you'll pretty soon get an idea if things are going to be tricky, in which case, just leave it there.
