You have a joint tenancy with your ex-partner

Whether you are married, in a civil-partnership or living together, you have a right to stay in the home, and the court can enforce it.

If your ex-partner decides to leave the property and gives the landlord notice, this may also end your tenancy. Your landlord may agree to transfer the tenancy to your name only. If your ex-partner leaves and refuses to pay the rent, you are liable to pay all the rent and any arrears, even though you are joint tenants.

A court can order to allocate the tenancy to one of the tenants. The order is likely to be in favour of the person who has the children living with them most of the time.
