Hi sudeep39

I feel the correct usage is "at your own expense".

If you cannot afford a lawyer, one will be provided for you at government expense

Example:

My company pays for my travel expenses, but any entertainment is at my expense.

I think 'at' is the proper preposition. It is same as "Park at your own risk"
