How to formulate a legal description of code refactoring and requirements for a contractor to refactor before handing over an information system?

Question

Outsourcing

There was a web development department inside the company, at some point the head of the department left the company and organized his own web studio, at the moment I need to accept the developed information system from them (website and content management system based on 1s Bitrix solution). I don't want to accept work from them until the code is refactored.
Question: how to formulate a legal description of code refactoring and requirements for the contractor to carry out refactoring before handing over the information system?

Answer 1

The very word "refactoring", no matter how clever it may sound - does not give anything.
We need specifics.
As an example, attach requirements for code style , etc. to the contract. and demand their performance in the contract.
This will automatically pull refactoring along with it.
