Hypothetical scenario here (sort of!). Married couple - dh works full time and dw works p/t flexibly in order to look after the couples children. They divorce and sell house. Dh gets approx £30k which he uses as a deposit on a flat, he has always had a steady income so no problem in securing mortgage.
Dw gets approx £50k. larger share because she will have the main custody of the children. Because dw put her career on hold mortgage companies won't touch her with a barge-pole so she has to rent. Renting very expensive at around £900 per month. Dw can not claim housing benefit because her share of the equity is more than the £16k allowed.
Do you A) Spend the money on rent and accept that it will be spent in a couple of years and you will never have the the same choices as Dh.
Or
B) Blow the cash and just keep £16k in your savings account so you can claim housing benefit.
Or
C) Let dh have most of the equity and tell him to invest it wisely with the intention of giving it to the children when they are older.
