is it possible to claim ownership of said land
There are some land which are known as 'enemy's land or property. The properties which were owned by Muslims, who have migrated to Pakistan (known as present day muhajirs) during or after partition, their land came under the respective DMs. If that is the case, then it can not be occupied by you. Try to get it allocated to you through legal process.
