An important update for this post (now locked) british-citizenship/format-of-referee-s ... 25084.html

Any forms that need signing (referee, family consent) can be signed electronically. The Home Office just wants a PDF with a visual representation of the relevant signatures that tis faithful to the original. How you do that is up to you. If you can sign everything directly on a digital document (with an electronic pen, or by uploading and attaching an image file of your signature to the document), that is valid too, no need to print, sign, and scan.

I just received the approval email for my partner's application, while having signed everything directly on the PDF using DocHub. No issues whatsoever.

I want to clarify that I have only tested digital signatures that are a reasonable true visual representation of the real world signature, e.g. signing the PDF by using the mouse or e-pen over the PDF in the same way you would use a pen on a paper; or including a .jpg or .gif file of your scanned signature (or of your signature produced by mouse or pen). In short, anything that in the end looks like your real-world signature.

I do not mean other digital signatures (like email identity, and symbolic typing) where the visual aspect of the real-world signature is not present (see the options I discussed in the original thread linked above).
