I haven't really tried this before, but just a suggestion.

There is e-will services offered by some banks, like Maybank and HLB. There, you can get the will templete from Amanah Raya (The will format)

If you dun want to pay them RM 200+ for that services, maybe you can download that form, type out and change some of the "name" such as trustee and etc...

After complete, then u go to lawyer and stamp it.

Of course, all other procedure applies, such as getting 2 witness to sign..
