Jersey Civil Registration
For certificates after 1842 contact:
The Superintendent Registrar,
10 Royal Square,
Office Hours 9.00-12.30 p.m.
If you know the Date/Name/Parish of the event, the cost is £20 per certificate (as at 2011).
If searching is required, a further charge of £7 is levied for a five year search for a birth or death or £14 for a five year search for a marriage.
Add a postal handling charge of £1, for overseas and £0.50 for the British Isles.
Cheques should be made payable to "Treasurer of States."
As long as there isn't a wedding taking place you can look at the books for free.
If you are in Jersey, these charges can often be alleviated as the Registrar's Indices from 1842-1900 are available at both the Societe Jersiaise and the CIFHS Research Room.
