The facts that the defendant, The Safe Deposit •Company, by answer offered to abide by the judgment of the court, and did not appeal from that judgment, enable us to dispose of this appeal upon the sole consideration of the rights of the other parties to this action respecting the usé of the safe in the •vaults of the Safe Deposit Company and the right of access thereto, freed from any embarrassment which might have arisen if the defendant, The Safe Deposit Company, had asserted the right to control the use of the safe and access to the vault upon its premises, against the desires of the plaintiffs. So also does the fact that George W. Patterson upon the death of plaintiffs’ testator .assented to a lease of the safe to himself and plaintiffs jointly, dispose of any question as to what his rights were prior to that lease bv reason of his survivorship, and renders a discussion of such rights futile.
Admitting that upon the death of John Patterson the defendant George W. Patterson became vested with the exclusive right to the use of the safe, it was nevertheless competent for him to .surrender his interest and this was effectually accomplished by bis assent to, and acceptance of, a lease inconsistent with his rights as sole surviving lessee under the former lease. The new lease constituted the plaintiffs and defendant Patterson joint lessees, and whether their relation thereunder was that of joint tenants, or tenants in common, is equally immaterial in disposing of -the question presented for adjindication, since either relation involves the application of the same principles of equity jurisprudence.
“ Equality is equity,” and steadily adhering to the application •of this familiar maxim courts of equity have ever regarded the rights of joint tenants and tenants in common respecting their common estate to be reciprocal, neither being permitted during the continuance of the cotenancy furtively to acquire and hold any advantage which would not also enure to the other’s benefit, x provided the latter manifests a willingness to assume his just proportion of any burdens attending its acquisition and maintenance. Washburn on Real Property, vol. 1, p. 557, star paging 411, p. 566, star paging 418. So one of several cotenants will not be permitted to purchase and retain for his exclusive benefit, and for the purpose of disseizing and expelling the others, any outstanding adverse title, but will be deemed in equity to hold such title in trust for the benefit of such of the cotenants as will contribute towards the expense incurred. Van Horne v. Fonda, 5 Johns. Ch., 388, 406; Swinburne v. Swinburne, 28 N. Y., 568 ; Fallon v. Chidester, 26 Am., 164; Wears v. Van Meter, 20 id., 616; Armour v. Alexander, 10 Paige Ch., 571.
*816And this principle is extended to others jointly interested in, the maintenance of an estate, such as life tenant and reversioner or remainderman. Dickinson et al. v. Codwise et al, 1 Sandf. Ch.,. 214, 226; Whitneg v. Salter, 1 Am. St., 656.
The constructive trust for the benefit of all the co-tenants growing out of the purchase, with intent thereby to secure unfair advantage, by one of any interest in the common estate, by means whereof the rights of the others will become jeopardized, lessened or impaired, and which finds its incipiency in the unity of interest of all, seems to subject the present case to the influence of" those equitable principles upon which a partner is deemed to hold, a renewal to himself of the lease of the co-partnership premises, intrust for the benefit of the co-partnership and all the members, thereof, as interpreted by the court of appeals in the leading case-of Mitchell v. Reed, reported in 61 N. Y., p. 123.
Approving of many similar cases adjudged in this state and elsewhere, the court, in Mitchell v. Reed, firmly declares it to be-the law of this state that, though the lease may contain no covenant of renewal by the lessor, courts of equity will nevertheless, pi’otect a lessee in possession in the enjoyment of his mere chance-of expectancy of renewal by the lessor against the clandestine acts of those standing as to the lessee in an attitude of trust and. confidence. Such was the attitude of the defendant Patterson, towards the plaintiffs as hereinbefore shown respecting their rights-as joint lessees with him- of the safe in question, and the conclusion reached by the learned trial justice to the effect that the renewal of the lease taken by the defendant Patterson in his own name, while the former lease was as yet unexpired, though not to take effect until after such expiration, meets with our unqualified approval and assent.
Nor have we any doubt of the power of a court of equity to entertain this action and to grant the relief awarded. The main relief sought was to enforce the execution of a trust respecting the use of the safe, the legal title to the leasehold interest in which, under the renewal, was in the defendant Patterson, the equitable-owners being the lessees under the former lease, including these-plaintiffs. The remedy at law by an action for ejectment was inadequate, since the legal title of the defendant would effectually bar the recovery of possession against him by that means. Proceedings to recover the securities and papers deposited in the safe, or an action to recover the value thereof, could only result in partial relief to the plaintiffs, since possession of the safe, or access thereto, could not be therein awarded, and the contents thereof' might not be susceptible of pecuniary recompense. Clearly, then, the only adequate relief was to accord plaintiffs that access to the safe to which, as beneficiaries of the leasehold interest, they were-entitled, and the exclusive jurisdiction of equity in matters of trust authorized that court to take cognizance of the action..
The novelty of the question to be determined in adjusting the-matters in controversy is not an obstacle in the way of administering exact justice, National Tradesmen's Bank v. Wetmore, 124 N. Y, 241; 35 N. Y. State Rep., 316, and the court having ob-*817tamed jurisdiction of the subject-matter of the action and of the parties thereto will award relief adapted to the exigencies of the case. Valentine v. Richardt, 126 N. Y., 272, 277; 37 N. Y. State Rep., 12. Jurisdiction once acquired by a court of equity will not be divested because it appears that partial relief was obtainable at law, but the court will proceed to administer complete -relief and may for that purpose decree the possession of land which, but for the matters of equitable cognizance, was recoverable only by means-of the common law action of ejectment. Pomeroy’s Equity Jur., vol 1, §§ 177, 180,185.
The judgment appealed from is not invalidated because in express terms it authorizes the plaintiffs to take possession of such of the contents of the safe as belonged to them in their representative capacities or as individuals. The clause is wholly immaterial, for without it the effect of the judgment awarding plaintiffs access to and egress from the safe, would have been the same. No particular item of property is awarded to the plaintiffs, and having obtained access to the safe it was their right, by virtue of their ownership as executors, or individuals, to remove whatever-belonged to them in either capacity. No greater right is given by the judgment, and defendant is in no manner prevented from having like access to the safe and from removing therefrom so much of the contents as to which he is entitled to possession.
Thus, if any controversy should arise between the plaintiffs and the defendant Patterson concerning the right to the possession of any specific item of property, it would be left to be determined in subsequent proceedings.
The judgment appealed from should be affirmed, with costs.
