cheque paid in Monday
goes through clearing house Tuesday
Arrives at paying bank Wednesday.
If returned unpaid will be back at your Bank thursday to be debited.
Cleared funds Friday for withdrawal.
Could be late returned up to noon Thursday. but should phone your bank to let them know.
However at this time of year a returned cheque could be delayed in the post.
Also I think the rules on forged cheques has been changed since I retired and it could be returned unpaid several weeks later.
