Generally speaking (as we don't know the circumstances), you can submit a money claim against a company out of jurisdiction (England and Wales) although you would need to submit a form N510 (you can get a copy here) with the claim form and may need advice on if this process is appropriate, filling in the forms, fulfilling service requirements, timescales allowed, requirements for obtaining Judgment if this arises, enforcement etc... to ensure compliance with the CPR and knowing when you can do what and what you need to do by when.
