I recently lodged 6 figures worth of cheques to my current a/c and subsequently wrote a cheque to clear mortgage with the funds (short term family loan as have just sold house but sale funds wouldn't be available for use until after the closing date on PTSB tracker bonus offer). Asked when lodging cheque for €15k would there be questions asked when others come in and told once it was clear where they were from it would be fine. Nothing was mentioned when lodging the others and all were cleared no problem, including the one we wrote.
