There is only one ground for Civil Partnership Dissolution in England and Wales and this is that the civil partnership has irretrievably broken down.
A dissolution petition can be based on one of the following four facts:
1. One party has behaved unreasonably such that the parties cannot be expected to continue living together;
2. One party has deserted the other for a period of 2 or more years;
3. The parties have been separated for a period of 2 or more years AND both consent to the divorce;
4. The parties have been separated for a period of 5 or more years.
If any of the above apply, you are entitled to petition for Dissolution.
