Solicitor asking for more money months after completion due to their error

[walterwhitesgf]

Sale completed on property August this year.
My solicitor paid all dispersements including Estate Agents fee and transferred the balance to me.
I received an email today saying they made an error drawing up the completion statement showing the estate agent bill as £800 short meaning they paid me £800 too much. They have paid the correct amount to the EA so now have a shortfall in their accounts and want me to pay them £800.
Other than to check the amount they paid me was about what I expected ,I didn't scrutinise the completion statement as I assumed everything would be correct.
Any legal people able to advise me ? My initial response was ...not my mistake .Do I have to pay them ?

Mine got in touch with me too about 8 months after completing. They were chasing me for £1.60!!

My solicitor transferred me £11,000 too much upon completion of my sale.

I immediately called to pay it back.

Its what you do so yes, you have to pay it otherwise it's theft.
