Yes. Singapore law provides strict enforcement measures to ensure that the obliged parties fulfill their obligations.
In situations where the party does not fulfill these obligations, the recipient of the maintenance can make a Garnishee Order or an Attachment of Earnings Order [AEO], which obliges a bank or an employer to deduct a portion of funds or salary and make transfers for maintenance.
There are other enforcement options available depending on the situation. Please get in touch for further information.
