These are agreements entered into voluntarily by two parties who are either intending on becoming married, or where they are married.
The agreements can set out what you want to happen with your assets if your marriage breaks down in the future. If you have your own assets, for example a house, which you want to protect these agreements can give you piece of mind and can protect the financial interests of children you may already have from previous relationships or marriage.
Do not be tempted to “do it yourself”. These agreements are unlikely to be upheld by the court if you have not had legal advice or if the document is not drafted properly. If both parties are certain that they wish to enter into such agreements, they must be made aware of the uncertainties.
