 Re: What do we do now please?
This all depends if it is a formal offer in writing.
If it was just a telephone confirmation, I personally would not stop the court action until I had the cheque or money in my account or at least a definitive promisory letter. If Woolwich are serious, they can get the money to you by Tuesday latest.
On Monday, I would ring the person who you last spoke to and tell them that you have been in contact with the court and have been advised to secure the full amount (or a letter confirming agreement to pay the full amount) of your claim before withdrawing the claim.
Remember, this amount should also include the court costs and 8% interest (if you added this in your claim) - if they haven't offered these two additional elements in their settlement, then they are not offering the full amount of your claim. In which case, this may be why they want you to withdraw - it would save them money and they know they will have to pay it if you press on!
Basically, tell them to put their (your) money where their mouth is. If they say they won't deposit before the 4th of April or won't put it in writing so you receive the letter before the court date, don't cancel the claim.
It is not unknown for some banks have put it in writing and brought the letter to the actual hearing to hand to the claimant on the day. |
