Q: Can I write in extra things in the SA with
blue/black ink like a bank accnt?

A: Of course. What you add as particulars is what the
State can not do they can only enter generalities. This 
gives you a stronger claim when it comes to the nitty 
gritty - details always overrule generalities. "I can prove
that is my little girl who was abducted 5 years 
ago. Look above the hair line at the back and 
you will see a faint scar in the shape of an s 
from when she fell off her high chair when she 
was 8 months old. The incident is on record 
at the county hospital."
