The law of the place of enforcement.
For registering a judgment under the Foreign Judgments Act 1991 (Cth), 6 years after the date of foreign judgment or after the appeal is complete (if any), whichever is the later. More generous time limits apply for enforcement of judgments under the common law and vary depending on each State and Territory.
The limitation period for enforcing an award is usually 6 years except in the Northern Territory where it is 3 years. The limitation period may be up to 12 years in some States or territories where the arbitration agreement is made or contained in a deed rather than an agreement.
