Guernsey Court Hierarchy & Reciprocal UK Enforcement

REMO Reciprocity

Domestic Guernsey Court Orders

Claims are filed in the Magistrate's Court (summary proceedings) or the Royal Court (during divorce proceedings). The court examines net surplus after high local accommodation costs.

UK Reciprocal Enforcement (REMO)

Under the Maintenance Orders (Enforcement) Law, CMS assessments or court orders issued in the UK can be registered in Guernsey and enforced by Her Majesty's Sheriff via wage arrests.

The Legal Framework in the Bailiwick of Guernsey

The Bailiwick of Guernsey is a self-governing Crown Dependency with its own separate legal system founded on Norman customary law and local statutes. The UK Child Maintenance Service (CMS) does not have direct administrative jurisdiction in Guernsey unless an order is formally transmitted via reciprocal enforcement conventions (REMO).

Housing Market Disparities and Child Maintenance

Because Guernsey operates a strict two-tier housing market (Local Market and Open Market) characterized by high property prices and rents, Guernsey courts give substantial weight to reasonable housing expenditure before assessing disposable income available for child support.

Enforcement via Her Majesty's Sheriff

If a parent defaults on a Guernsey maintenance order, the court can issue a summons under the Maintenance Orders (Enforcement) Law. Persistent default can lead to wage arrestments executed by Her Majesty's Sheriff or committal to Guernsey Prison (Les Nicolles) for contempt.

Frequently Asked Questions: Child Maintenance Calculator Guernsey

Authoritative answers based on current statutory rules and legal precedents

Can the UK CMS deduct money from my Guernsey bank account? ↓
The UK CMS cannot freeze a Guernsey bank account administratively. They must forward the assessment to the Guernsey court under reciprocal enforcement arrangements (REMO) to obtain a local Guernsey enforcement order.
Does Guernsey have a statutory percentage formula like the UK CMS? ↓
No. Guernsey courts evaluate the realistic budget of the child and the net surplus income of each parent on a case-by-case discretionary basis.
How does maintenance affect Guernsey income tax? ↓
In Guernsey, court-ordered maintenance payments made to children under 18 may be allowable as deductions under Guernsey Revenue Service rules, subject to statutory caps.
