A prenuptial agreement is an agreement between two people before they get married or enter into a civil partnership. It sets out the property and money that belong to each person before the marriage or civil partnership and clarifies what is intended to remain the property of that person after the ceremony and even after the marriage/civil partnership itself.
If you and your future spouse or civil partner have assets which each of you would like to own as individuals rather than jointly, record these assets in a prenup. This will ensure that any assets, be it property, cash or heirlooms owned prior to marriage or civil partnership will be owned by the individual and not jointly. This premarital or pre-civil agreement covers situations where both parties have taken independent legal advice.
