Thank you all for the help

Oral agreement is still recognized and binding in Malaysia but it will involve a lot of complexities (like he said, she said and … etc.)

Besides, every day you are entering into a verbal agreement. You just don’t know it.

Example:

When you go and repair your car. When you buy grocery in a market. When you need plumbing service. Etc…

i learn from Google.

book ermm... contract act 1950.

I go one step further and quote you the section:-

9. Promises, express and implied
So far as the proposal or acceptance of any promise is made in words, the promise is said to be express. So far as the proposal or acceptance is made otherwise than in words, the promise is said to be implied.
