Pursuant to section 16AC (1)(b) of the HDA 1966, an order of the Tribunal is final as is deemed to be an order of the Magistrate's Court or Sessions Court, as the case may be, and can be enforced by any party in the proceedings.

As your judgment sum is 26k, it will fall under the jurisdiction of the Sessions Court. As such, if the developer still refuses to comply, you need to enforce the order at the Sessions Court. Your options are:
1) Writ of seizure of sale - where the bailiff will seal and subsequently auction off the developer's goods in their premises;
2) Judgment debtor summons - where the directors of the Company would be compelled to attend Court to be questioned as to their respective financial capacity; and
3) Garnishee proceedings - where obtain a Court order to compel their bank to 'freeze' a sum equivalent to the judgment and remit same to you.

If you wish to go all the way, you can also issue a notice of demand pursuant to Section 218, Companies Act to give them 21 days to pay up, failing which you proceed to file a winding-up petition against the developer at the High Court. To wind-up the developer means to close them up (as they say 'tutup kedai')

At this stage, you would need to seek legal advice and your lawyer can advise you as to the best method to get your money.
