Under Section 6(a) of the Transfer of Property Act, 1882, which of the following CANNOT be transferred?

Section 6 of TPA, 1882 specifies properties that cannot be transferred. Section 6(a) specifically prohibits the transfer of a chance of an heir-apparent succeeding to an estate, a chance of a relation obtaining a legacy on the death of a kinsman, or any other mere possibility of a like nature. This is the doctrine of spes successionis a mere hope or expectation of succession has no present existence and may never materialise, hence it cannot be the subject of a valid transfer. Other non-transferable items under Section 6 include a right of re-entry (Section 6(b)), an easement apart from the dominant heritage (Section 6(c)), an interest restricted to personal enjoyment (Section 6(d)), a right to future maintenance (Section 6(dd)), and a mere right to sue (Section 6(e)). Leasehold interests, actionable claims, easements transferred with dominant heritage, and mortgages are all validly transferable.
