Can you auto lock only used fields on PDF forms?

[Michael27167458tjm4]

We are looking to convert a physical living document into a fillable form but to do that we need to be able to lock any fields that are completed while leaving untouched fields. For example the whole form PDF would be fillable. is user A completes all the fields in section 1 and saves it, when User B goes in to complete section2 they can not change the fields in section 1, but can still enter in values to section 2. Is something like this possible?

Yes, something like that is possible. There are a few different possible solutions.

One easy solution is to use the Adobe Sign service. I think they are calling it "e-signing" now. The basic version comes free with an Acrobat Professional subscription.   

Otherwise, there are some slightly awkard ways to use JavaScript to create this kind of workflow.

If having them sign the form is the only way for this to work, is there a way to create multiple stages of signing in the same form? can I tie specific fields to a signature so that different sections of the same document can be independently locked by signing?

- If you use digital signature fields, then yes, by simply adding multiple fields.

- Yes, you can set each field to lock specific fields only when signed.

[Thom Parker]

Both using signature fields, and the Adobe Sign service, which was designed for exactly this type of workflow.

Yes, it's possible, either using a digital signature field or a button with a script.
