Welfare Reform Bill

Something has been puzzling me. We are talking about self-employed as if it were a self-employed single person. What happens if you have a small family business—not quite the corner shop—where the income from that self-employed business in which the partner, say the wife, is doing some part-time book-keeping, answering the telephone, and so on and contributing to fairly low profits? How will you assess whether conditionality applies to her?
