Before we were married, my other half was intermitently staying with his parents - when his dad died, his mum was struggling as a very small pension put her a few pounds over the limit for benefits and hence she was worse off. He subsequently sold another flat he had bought with a former girlfriend and bought her council house as he was counted as resident. The mortgage did not have to be in her name, although the property was in joint names. She lived in the property rent free for the rest of her days as he moved out shortly after. I think that in your situation, your in laws would have to be on the titles, whether this would be held against them should they subsequesntly want to claim benefits, I am not sure. I do think though that they would have great difficulty in obtaining a council house, although they may be able to get a private rented property. I think that whilst it might not be what you want to hear, i think that legally and morally you are not going to be able to carry out your plans. I think that you could arrange to transfer the tenancy into your wifes name as she has been resident in it for all those years, I think that you would then have to wait until you qualified for a discount in your own right. Your in-laws would still struggle to get a council property, but may be eligable for housing benefit for a private rental, you could continue with the tenancy until such time as you qualified for the discount. Don't know if that helps you. Incidentally, you need to consider what happens if your in-laws die while their names are on the title deeds, if your wife has any brothers or sisters, this could become sticky. i can appreciate how frustrating it must be when you are trying to get on the housing ladder, I don't know if there are any short cuts.
