Frankly, I think it is unlikely. Part of the reason for that is that it is not so easy to define a 'win' in matrimonial finance cases. The reality is that the same income and capital which used to support one home is usually divided so it has to support two homes. That means the standard of living of both spouses often drops - at least in the short term. Also, when it comes to 'fairness' judges often take the view that if both spouses leave court equally dissatisfied that means the decision was about right.
That is not to say that you might find a lawyer willing to be paid at the end from the asset(s) preserved or recovered (which is, after all, how the Legal Services Commission works in these cases) but that isn't so common either because it is a quick way for a lawyer to go bankrupt.
You can keep costs down by (1) taking legal advice to find out what you can realistically expect so you don't waste money on a fool's errand and (2) doing as much as you can thereafter for yourself and only seek legal advice when you have to or when it is sensible to do so.
