Expert writing Tips
Best practice
Always use "in their possession" instead of "on their possession" for grammatically correct writing. The preposition "in" is the standard way to indicate ownership or control.
Common error
Avoid using "on" when indicating possession. "On" typically refers to a surface or location, while "in" correctly denotes containment or control. Remember that saying something is "in their possession" implies they have it, while "on their person" means they are carrying it.
