These are payments made by your solicitor on your behalf during the course of a transaction and which you may be liable to refund,
Some disbursements are also subject to VAT such as barristers’ fees while some, such as court fees, are not.
If a payment described as a disbursement appears on your bill, it must be for the same amount that the solicitor paid – there can be no ‘mark-up’. Also, if the solicitor receives a discount for any reason the discount must be passed on to you.  
A solicitor can only give an undertaking that is within his power to meet – whether it is for making a payment or doing or not doing something. Failure to perform an undertaking given can result in disciplinary proceedings against a solicitor.
So, if your solicitor is asked to give an undertaking for a payment you should expect to pay money on account to ensure the solicitor is in funds when called on to make the payment. 
If the undertaking is to do, or not do, something your solicitor may ask you for irrevocable instructions, which means that even if you then change your mind, you will remain responsible once the undertaking has been given.
