Divorce is never that simple. Assuming you are eligible to divorce in both jurisdictions whether you are better off depends entirely on the individual circumstances.
In England & Wales it isn't too difficult to do the actual divorce yourself, but it is often the finances that are often the sticking point. Without a court order finalising the finances either party can make claims in the future.
In Scotland if there are no children under 16 or outstanding finances and you qualify for a divorce through the simplified procedure it is even easier than in E&W. However, if you are not eligible to divorce under the simplified procedure the court rules and procedures are complicated and it isn't just a case of reading them to understand. At this time I wouldn't recommend anyone to do the divorce themselves under the ordinary procedure.
Thanx, no children, long separation. Papers were filed in england by one party but no progress/co-operation to enable completion. Is it possible for other party, now living in Scotland, to begin new process by filing in Scotland?
The last thing you want is to get into a complicated and expensive jurisdiction battle. To divorce in Scotland the courts in England would need to dismiss the petition there first.
