What is the equitable doctrine of advancement and resulting trust as they apply between spouses?

Section 31 modified the equitable doctrines of advancement and resulting trust as they applied between spouses. For a discussion of these doctrines see Pecore v. Pecore, 2007 SCC 17, [2007] 1 S.C.R. 795 at paras. 20-23. Section 31 also resulted from recommendations of the Gushue Study. It had recommended, amongst other things, that the presumption of advancement in favour of a wife (on the establishment by the husband of a joint bank account, on transfer of property to the wife without consideration, or where title to property purchased by the husband is placed in the wife’s name) be abolished.
