A cohabitation agreement can cover: – how each of you contributes to rent, mortgage or household bills – how each of you will deal with any debts – the fact that if you own a property each of you may have contributed differently to the deposit – how you deal with any joint bank accounts – taking out life insurance on each other – nominating the other as a beneficiary under a pension – what would happen to items you’ve bought together like cars and furniture – what would happen to your pets – how you will support any children you may have. Provided you’ve both been honest about your finances and assets, it’s likely that a court would enforce a properly prepared cohabitation agreement as it is a legal contract between you. If you go on to get married you could consider a pre-nuptial agreement. Although not legally binding, a pre-nuptial agreement would be taken into account by the court in any proceedings between a married couple or civil partners should they separate.
