Filling in the gaps on squatter's title

What is adverse possession?

Adverse possession allows a squatter to obtain a right to possess land by occupying it long enough under the Limitation Ordinance (Cap. 347) to "extinguish" the original owner's title.

Except for government land, no action to recover landed property is allowed after 12 years from the date upon which the right of action accrued. Time starts to run when the owner has been dispossessed of his land and the squatter has taken exclusive possession.
