I think that a formal agreement, binding contract will be very useful, even important for the power transfer to the Woman. Also some sort of repetitive ritual where her male confirms his submission and She her ownership of him, will add even more to her authority in the relationship.
If she want a marriage, her control should be written into the marriage contract, maybe in somewhat subtle terms designing her as controlling family finances, he taking her family name, all property in her name etc.
A real TPE FLR is not real until the Woman controls economy and finances, and the male hands over his paycheck.
