When can a case be referred to the International Debt Unit, MARD team

Where you are pursuing a UK tax or duty debt for a debtor that lives in, or has assets in, another member state, you can ask the International Debt Unit, MARD team to send a request to that member state asking them to assist in either:

  • providing information, such as checking an address, confirming the identity of a resident or whether they have any means of payment of the debt
  • notifying/serving legal documents on our behalf
  • recovering a UK tax or duty debt on our behalf.


If the request meets the criteria set down in the legislation, the International Debt Unit, MARD team will send the request to the other member state on your behalf. If it is a request for recovery, they will not send a request unless the debt outstanding is for 1,500 euros or more. They will also not send a request if the debt is currently being disputed.

Who can refer a case to the International Debt Unit, MARD team

Cases can be referred to the International Debt Unit, MARD team by any debt management team involved in the recovery of a UK tax or duty debt from a debtor living in another member state.

How to refer requests

The action you need to take depends on the type of request.

Requests for information

Send an email to the International Debt Unit, MARD team using inbox(This content has been withheld because of exemptions in the Freedom of Information Act 2000) with the following information:

  • the other member state to contact
  • the tax type
  • the age of the debt you are pursuing
  • the full name of the debtor
  • the legal status of the debtor
  • if an individual the maiden name of the debtor (if known)
  • if an individual the date of birth of the debtor (if known)
  • whether the debtor is the principal debtor, a co-debtor, or a third party holding assets of the debtor
  • the UK tax reference for the debtor
  • the address of the debtor in the other member state and whether this is a known address or an assumed address
  • the information requested.


If you are trying to trace a missing debtor, you need to provide at least a partial address in the other member state. It is unrealistic to ask an overseas authority to trace the debtor without this. Other member states will confirm doubtful addresses and provide details of lifestyle, assets and/or employment where possible.

  • if an individual the maiden name of the debtor (if known)
  • if an individual the date of birth of the debtor (if known)
  • the UK tax reference for the debtor
  • the full address of the debtor in the other member state
  • whether the debtor is the principal debtor, a co-debtor, or a third party holding assets of the debtor

  • details of the debt, including the date of establishment, a breakdown of the debt, when the debt should be paid by
  • contact details of the office to contact in the event of a dispute.

Request for recovery

Before you can refer a request for recovery to the International Debt Unit, MARD team, you must ensure that:

  • a MARD10 SEES letter or equivalent has been sent to the debtor at their overseas address and that the debtor has failed to respond to this
  • the debt is not in dispute and any appeal period in respect of the debt has elapsed
  • the total debt is for at least 1,500 euros (including interest, penalties and UK costs incurred)
  • recovery action in the UK is not appropriate
  • the individual or company liable to pay the debt is resident or has assets in another member state. If the debt is for a limited company, it is the company that must be established or have assets in the other state, not the director.

To make the request:
