Witnesses cited to give evidence in a legal aid case are entitled to make a claim for any out of pocket expenses and/or any financial loss incurred for the day(s) they have given evidence in court.
A claim may be made for the following expenses if the relevant evidence is produced.
We will meet the cost of out of pocket expenses which we assess as being reasonable and necessary.
Receipts need to be produced to vouch for any travel claim submitted. Without the relevant receipts payment cannot be considered.
The assessment will include consideration of the following factors:
If the witness has travelled by car we will only pay the mileage rate that is set by HMRC based on the rates in use on the date they travelled. You can find these rates on the HMRC website (link to external site). It is updated every six months in recognition of fluctuating fuel costs. The fuel costs are based on a car with an engine up to 1400cc. We can make no additional allowance for cars with larger engines.
You will need to be produce receipts before we can consider reimbursing any costs incurred by a witness.
Where the witness incurs financial loss we will consider making payment. Our policy follows other relevant rules including the Act of Sederunt in respect of the fees payable to witnesses.
“A person who is cited to give evidence and in consequence incurs financial loss shall be allowed reimbursement, being such sum as the Auditor may determine to have been reasonably and necessarily incurred by the witness, but not exceeding £400 per day.”
We will only make payment in a legal aid case if the following conditions are met:
We will not meet the cost of any sum claimed if the witness is unable, for whatever reason, to produce evidence in support of their claim.
The maximum that will be paid by us to a witness for loss of earnings is £400 per day (net loss).
