Both civil partners have a right to remain in the home, regardless of who bought it or has a mortgage on it. This is known as home rights. You will have the right to stay in the home until a court has ordered otherwise, for example, when dealing with the breakdown of your civil partnership.
If you and your partner are ending your civil partnership, the long-term right to ownership of your property can be decided alongside dissolution proceedings. The court has the power to transfer property regardless of original ownership. However, if you are not separating legally, the court will only agree to transfer ownership of a property if it is in the best interests of your children.
If you are the sole or joint owner of the home, your partner will not be able to sell it without your agreement.
However, if your partner is the sole owner, you will need to register your home rights in order to protect your interests. Unless you register your home rights, you will not be able to prevent your partner from selling the home or be able to remain there if it is sold.
You can register your home rights, regardless of whether or not you are still living in the home.
You will need to register your home rights with either the Land Registry or at the Land Charges Department, depending on whether your home has already been registered or not.
If you register your home rights, they will show up when buyers do a search on the home. This would make them aware of your right to stay in the home and prevent the sale going through.
