If a warrant is issued for none payment of a debt then a creditor can have the debt enforced in any country in the world as long it is a signed up member state of the Hague Convention. But the reality is very different because the court service in the member state usually needs to be satisfied that initial proceedings where lawful and reasonable by its own standards. "rgaine" you do not say what the 300,000 is, if its pounds then I would suggest thinking twice before thinking you can just forget this debt
