You have to show the relationship has irretrievably broken down, and that you have good reasons for ending the civil partnership.
There are 4 grounds for ending a civil partnership:
1. Unreasonable behaviour
Your partner has behaved so badly that you can no longer bear to live with them.
This could include:
- physical or mental cruelty
- verbal or physical abuse
- being irresponsible with money
- being sexually unfaithful
Your partner has left you:
- without your agreement
- without a good reason
- to end your relationship
- for more than 2 years in the past 2½ years
You can still claim desertion if you have lived together for up to a total of 6 months within this period.
3. You have lived apart for more than 2 years
You can get a dissolution if you have lived apart for more than 2 years, and both agree to end the civil partnership.
Your civil partner must agree in writing to end the civil partnership.
4. You have lived apart for more than 5 years
Living apart for more than 5 years is usually enough to end a civil partnership, even if your civil partner disagrees.
