It would depend on the nature and the formality of the loan between you. Also it isn't a 'given' that associates are excluded. The debt should be included, but, the voting rights of associates are treated differently. They are also, at times (not every time), asked by other creditors to forego their right to a dividend payment or set the debt aside until the IVA is concluded.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
