Hi KoChin,

Just my 2 cents as an "end user" for Public Trustee's & Pacific Trustee's Will writing services:
1. Item 2:
U may want to reword as such:
If my spouse, XXX XXX XXX predecease me or shall not survive me for a period of one month then I, HEREBY DECLARE that

2. Attachment 1:
I'd suggest not including it such way in the Will
BUT just state it as an "Asset & Liability list", thus can be updated anytime for your Executor to know where & how to get to your assets.

3. U may want to have another survivorship clause for Executor & Trustee
especially someone / legal entity that doesn't usually travel or be near your wife or your bro-inlaw
choy choy choy BUT ACCIDENTS HAPPEN and if all the Executors are usually travelling together or near each other..
one-shot both koyak how?

4. Items 8 & 9:
Choy choy.. but survivorship clause may be a bit unclear.
eg IF (CHOY! ya - my apologies if my IF offends) child PASSES after U
AND does not have child(ren) of their own
.. er.. so.. how?

5. Guardianship for your children?

I'll "clean up" my simple Will
+ complicated as kaka Will cum Trust
to share later.. er.. hope i can find time heheh

BTW, good share 

Here's the simplified Will i drew with PB Trustee years back.
urgh.. sorry, i couldn't convert to MS Word to remove the data,
thus screenshot and used red squares to block off private data.

Note - Trustee here is a Company, thus Company No.
Please change to IC Number if human
