Hi Derek,
Are you concerned because the marriage was conducted in England? Given Australia and England are so similar in law and they easily recognise certificates and decrees from the other country, your partner can apply for her divorce here or in England. Whichever is easier.
If she applies for the divorce decree in Australia, it will be according to Australian law. It will need to be recognised in England if she needs it recognised there in the future. Whether it is recognised or not depends on the English laws. However, I would say there is a good chance of it being automatic (or fairly automatically) recognised there.
The opposite is true if she applies for divorce in England (i.e. she needs it recognised in Australia, which is easy to do for an English decree).
To apply for divorce in Australia, she will need to show:
- Her and her ex husband has been separated for at least 12 months; and
- There is no reasonable likelihood of the relationship reconciling.
She can apply online and she can as a sole applicant (by herself).
