1. The rules in respect of limitation are contained in the Limitation Act 1980:
a) Actions upon simple contracts prescribe within six years of the accrual of the cause of action.
b) Actions upon contracts under seal must be brought within twelve years of the accrual.
c) Actions for damages consisting in or including damages in respect of personal injuries prescribe within three years
(subject to the same rules which apply in tort).

2. Time starts running at the accrual of the cause of action, subject to the following limitations:
a) Where a person is liable for liquidated damages, time will start to run against him afresh
aa) from the date that he make a written acknowledgement of his indebtedness or
bb) from the date that he make a part-payment of the debt.
b) Where the plaintiff is a minor or unsound of mind, the time starts running from the moment when the disability ceases or the minority ends respectively, or from his death, whichever occurs first.
c) Where the action is based upon fraud, or where the right of action is concealed by the defendant's fraud, or the action is for relief from the consequences of the plaintiff's mistake, the period does not begin to run until the plaintiff discovers the fraud or the mistake, or could, with reasonable dilligence, have done so. 'Fraud' in this context also includes 'equitable fraud', which includes any form of unconscionable concealment even though not involving moral turpitude:
Applegate v. Moss 1971 - construction buddy concealed bad work, time started upon discovery.
d) With regard to personal injuries, time does not start to run until the plaintiff's knowledge of the injury in respect of such injuries as develope slowly and may not be discoverable until long after the event which caused them.

3. Claims to equitable remedies are not regulated in the Act. Instead, they are governed by the equitable doctrine of 'laches'. The principle is that it is unjust to permit a person to sleep upon his rights - this might be evidence of acquiescence in the infringement of the right violated, or may give rise to such changes in circumstances that it may become unfair to keep the other party to his bargain. The courts may apply the Limitation Act to equitable remedies by 'analogy' if the equitable claim is essentially similar to a claim at law.
Besides, the laches doctrine does not apply to a successor in title who claimes under him.

4. Equitable doctrin of 'acquiescence': Where a person who is entitled to a right, whether legal or equitable, acquiesces in its infringement to such an extent that it would be unconscionable for him to seek to enforce it, equity will not allow him to do so.
