For someone who might need it as I was struggling to find it too:

For cop pengesahan, I found it online at https://sraisc.files.wordpress.com/2012/02/...pemastautin.pdf

And then contact either your Ahli Parlimen Selangor, Pusat Khidmat DUN Selangor, Ahli Majlis Pihak berkuasa tempatan di kawasan tempat tinggal, penghulu/ketua kampung, pengerusi taman perumahan/ketua blok or ketua komuniti and then they will sign it off.

Then you can bring the form to Tawas.
