Under the Property (Rights of Spouses) Act, the starting presumption for the family home is usually a 50/50 division, but the court can vary that proportion based on factors like substantial improvements or financial contributions made during the marriage.
Remember there is a strict 12-month statutory deadline from the date of the Decree Absolute to file for property division in court! Do not wait until after the divorce is finalized to start discussing assets.
Mediation through your attorneys or court-annexed mediation is usually much faster and significantly less expensive than having judges carve up property over a two-year trial.
