What is the current state of the law on reciprocal benefits?

I agree with my colleague that reciprocal benefits should form no part of the benefit, detriment analysis and should be considered only at the juristic reason or quantification stages. I also agree that in this case, household expenses should not be taken into account, but I would not foreclose the possibility that in some cases it may be appropriate to do so (Blake v. Wells Estate, 2007 BCCA 617).
