Sharing from experiences of dealing with debt
The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

Hi - I'm assuming the partner lives with you? If so then yes, their income is taken into consideration, just to make sure a fair percentage is being paid towards household costs etc.
I'm not actually in an IVA ( legally) as its all in my hubby's name, but my income has to be declared.
The answer to your question is dependent upon a number of issues - such as how long you have lived together, whether you have any children, what the money you borrowed was actually spent on, and how much each of you contribute to the houseshold bills.
For a more definitive answer it might be sensible to arrange to chat things through with an insolvency practitioner.
