@panadol the academic writing company would not have sued you.
Nor did they have any legal frame of reference to sue you for using a paper you ordered from them.
You need not have feared that they would have put you in jail. I am pretty sure that you are still a free person 3 years later and most likely a graduate already.
The writers that work for any academic writing company knows that part of their duty is to turn in plagiarism free papers (first) and that all the rights in terms of using the model paper that they write is turned over to the student that ordered the paper (second).
The academic writing company makes this clear to all the writers who they hire. These two references form part of the terms of service that the writer agrees to when he is given the permission to accept student orders via the company ordering system.
So your fears were totally unfounded.
There was no way that the company or the writer who was assigned to your paper would have run after you in any legal way.
If you eventually decided to turn in the paper you received from the company as your own instead of using it as a model, I am sure that you already know by now that your fears were baseless. It was perfectly fine for you to turn in the model paper as your own.
You received all the rights to that paper anyway the minute it was turned over to you by the company as per the TOS policy of the company.
