Letting one person fill in a form, but then locking it

[SilbStu]

I am preparing a form for my client to fill in. Have done this many times, but here is a new wrinkle.

I want him to be able to update as necessary, but then be able to somehow lock it or change it from a fillable file to one that is static, so that he can distribute to his clients and then cannot mess with it.

Not sure how to do this.

THanks,

Stuart

Hi Stuart, 

Thanks for reaching out with your question. 

You can add a digital signature at the end of the form to and lock the form using the signature field: https://adobe.ly/4mEkixL;

Alternatively, you can add a password so people can't make changes to the PDF: https://adobe.ly/43V7xap

Lastly, you can try Acrobat Sign: https://adobe.ly/4mGTVag

Wait for more inputs from the experts.
