Agree with MrsBert the only way she can get proper advice is if she sees a solicitor specialising in this area. The solicitor needs full details of both parties' income and assets before being able to give an idea of a likely settlement.
If you want to know what principles the court takes into account when dividing assets, they are as follows:
*It shall be the duty of the court in deciding whether to exercise its powers to have regard to all the circumstances of the case, first consideration being given to the welfare while a minor of any child of the family who has not attained the age of eighteen.
*the court shall in particular have regard to the following matters—
(a)the income, earning capacity, property and other financial resources which each of the parties to the marriage has or is likely to have in the foreseeable future, including in the case of earning capacity any increase in that capacity which it would in the opinion of the court be reasonable to expect a party to the marriage to take steps to acquire;
(b)the financial needs, obligations and responsibilities which each of the parties to the marriage has or is likely to have in the foreseeable future;
(c)the standard of living enjoyed by the family before the breakdown of the marriage;
(d)the age of each party to the marriage and the duration of the marriage;
(e)any physical or mental disability of either of the parties to the marriage;
(f)the contributions which each of the parties has made or is likely in the foreseeable future to make to the welfare of the family, including any contribution by looking after the home or caring for the family;
(g)the conduct of each of the parties, if that conduct is such that it would in the opinion of the court be inequitable to disregard it;
(h) in the case of proceedings for divorce or nullity of marriage, the value to each of the parties to the marriage of any benefit which, by reason of the dissolution or annulment of the marriage, that party will lose the chance of acquiring.
The case law confirms that the court's overarching goal is 'fairness'. Fairness does not always mean 50/50 division, but generally if it is a different proportion than 50/50, this should be able to be justified using the factors above. Example: giving more than 50% to one of the parties, based on financial needs. Or giving less than 50% to one party based on it being a short marriage.
