What are the grounds for divorce for a same sex marriage?

There is only one ground for divorce/dissolution in England and Wales, and that is the irretrievable breakdown of the relationship. To prove to the Court that the relationship has broken down irretrievably, you must prove one of the following facts:-

  1. Adultery (but this has to be with someone of the opposite sex)
  2. Unreasonable behaviour
  3. Desertion
  4. Two years’ separation with consent
  5. Five years’ separation

The only difference for a single sex couple going through divorce than for an opposite sex couple is the ground of adultery. This is only applicable if the adultery has been with a member of the opposite sex
