Firstly, you  should open a file at the bailiff’s office to enforce the maintenance judgment. This allows you to keep tabs on the maintenance debt as it will be automatically updated by their computer to incorporate changes in the consumer price index and interest. Opening the file will also enable you to apply for an order to prevent your husband from leaving Israel if he returns (which he is likely to do to see the children) If he sets foot on Israeli soil, border police will prevent him leaving, and you can proceed with various sanctions, culminating in jail, to ensure payment. Alternatively, if you know where he is abroad, you can ask for permission to serve him with documents relating to the file at the bailiffs, and he will be told how he can pay and warned of the consequences of non-payment.
