If my financial contribution to the household was greater than my partner's, should the settlement be proportional to that contribution?

No. The salary and income of the partners in a Common Law Marriage (UMH) or Marriage are part of the property partnership, a partnership in which both persons participate in equal proportion in relation to the assets and debts. In other words, even if only one person has contributed financially to the support of the couple, while the other has devoted himself or herself to housework with a lower or no income, at the time of separation both persons are entitled to half of everything they have acquired during their marriage or UMH.
