N.Y. Real Property Actions & Proceedings Law § 541: Adverse possession, how affected by relation of tenants in common

§ 541. Adverse possession, how affected by relation of tenants in

common. Where the relation of tenants in common has existed, the

occupancy of one tenant, personally or by his servant or by his tenant,

is deemed to have been the possession of the other, notwithstanding that

the tenant so occupying the premises has acquired another title or has

claimed to hold adversely to the other. But this presumption shall cease

after the expiration of ten years of continuous exclusive occupancy by

such tenant, personally or by his servant or by his tenant, or

immediately upon an ouster by one tenant of the other and such occupying

tenant may then commence to hold adversely to his cotenant.
