Illinois Statutes Chapter 735. Civil Procedure § 5/13-106. Accrual of right of entry or to bring action

(a) When any person is wrongfully ousted from possession, his or her right of entry or of action shall be deemed to have accrued at the time of such wrongful ouster.

(b) When he or she claims as heir or legatee of an owner in possession who died, his or her right shall be deemed to have accrued at the time of such death, unless there is an estate intervening after the death of such ancestor or testator; in which case his or her right shall be deemed to accrue when such intermediate estate expires, or when it would have expired by its own limitations.

(c) When there is such an intermediate estate, and in all other cases when the party claims by force of any remainder or reversion, his or her right, so far as it is affected by the limitation herein prescribed, shall be deemed to accrue when the intermediate or precedent estate would have expired by its own limitation, notwithstanding any forfeiture thereof for which he or she might have entered at an earlier time.

(d) Paragraph (c) of this Section shall not prevent a person from entering when entitled to do so by reason of any forfeiture or breach of condition; but if he or she claims under such a title, his or her right shall be deemed to have accrued when the forfeiture was incurred or the condition was broken.

(e) In all cases not otherwise specially provided for, the right shall be deemed to have accrued when the claimant, or the person under whom he or she claims, first became entitled to the possession of the premises under the title upon which the entry or the action is founded.
