Limitation on the Duration of Possibilities of Reverter and Rights
of Entry Existing Before the Effective Date of the Act If Notice of
Intention to Preserve Not Filed.—A special limitation or a condition
subsequent, which restricts a fee simple estate in land, and the pos-
sibility of reverter or right of entry for condition broken thereby
created, shall be unenforceable and shall be extinguished and cease
to be valid, unless within the time specified in subsection (c) hereof,
a notice of intention to preserve such possibility of reverter or right
of entry is recorded as hereinafter provided. Such extinguishment
shall occur at the end of the period in which the notice or renewal
notice may be recorded and any fee simple determinable or estate of
fee simple subject to a condition subsequent shall become a fee simple
absolute. No disability or lack of knowledge of any kind shall pre-
vent the extinguishment of such interests in the event no notice of
intention to preserve is filed within the times specified in subsection
(c) hereof.

(a)    Who May Record Notice to Preserve.—Any person having
a possibility of reverter or right of entry may record among the land
records of the City or County in which the land is situated a notice
of intention to preserve his interest THE ENTIRE POSSIBILITY
OF REVERTER OR RIGHT OF ENTRY, if duly acknowledged by
such person. Such notice may be filed for record by the person claim-
ing to be the owner of such interest, or by any other person acting on
his behalf if such claimant is under a disability, or otherwise unable
to assert a claim on his own behalf.

(b)    Contents of Notice; Recording; Indexing.—To be effective
and to be entitled to be recorded, such notice shall contain an accurate
and full description of all land affected by such notice, which descrip-
tion shall be set forth in particular terms and not by general inclu-
sions; but if such claim is founded upon a recorded instrument, then
the description in such notice may be the same as that contained in
the recorded instrument. Such notice shall also contain the name of
any record owner of the land at the time the notice is filed and the
terms of the special limitation or condition subsequent from which
the possibility of reverter or right of entry arises. All such notices
which are duly acknowledged shall be accepted for recording among
the land records upon pay
