There was an unfortunate case 2 months ago where a managing director from a large company (which had closed) was arrested at the airport (thankfully not in front of his children) because he had been the signatory on a cheque which the company failed to honour. Unfortunately in the UAE a dishonoured cheque can be tantamount to a warrant of arrest.
When leaving the country or your company be sure that the company re-issues all post dated cheques (that you have signed) with a signatory other than yourself (unless you are confident that your company will honour the cheques). Remember also that you give the bank cheques when financing your cars, opening a bank account and of course there is the landlord.
