Divorce and dissolution are both ways to end legally binding relationships, but dissolution is usually for those in civil partnerships rather than for legally married couples. To apply for dissolution, you must have been in a civil partnership for at least one year.
Both divorce and dissolution can be ‘no fault’ in the UK, meaning a quicker and often more amicable separation, with no blame being attributed. Dissolution follows a similar legal process as divorce and also requires arrangements for children, finances, etc.
