What a remainderman owns is genuine, and what they can do with it is almost nothing. California puts the constraint precisely: "A future interest entitles the owner to the possession of the property only at a future period." The interest exists now, is a property right now, and delivers no possession, no rent, no occupancy and no control over the property until the life tenant dies. A remainderman can in principle sell or give away the remainder, and section 769 says so expressly, but there is rarely a buyer for an interest whose delivery date is unknown, so in practice the interest is illiquid.
The remainder is protected by default, and it is the default that people assume is universal. California provides at section 741 that "no future interest can be defeated or barred by any alienation or other act of the owner of the intermediate or precedent interest," subject to the exceptions that section names, and at section 742 that a future interest valid when created is not defeated by the precedent estate ending early. So an ordinary life tenant cannot sell the property out from under the remainderman, cannot give it away, and cannot lose it by abandoning their own interest. Selling the property requires the remainderman's signature, which is the practical form the protection takes.
An enhanced life estate deed removes exactly that protection, and this is the single most important thing for a named remainderman to check. These instruments reserve powers to the life tenant that the default rule would not give. The Florida Department of Revenue, ruling on the documentary stamp tax treatment of one, quoted the recorded deed: the grantors reserved "a LIFE ESTATE with full power and authority to grant, sell, convey, reconvey, mortgage, encumber, lease, renounce, divest, transfer, assign, gift, hypothecate or otherwise dispose of the ... property, in fee simple, with or without consideration, without joinder of any Remainderperson," together with "full power and authority for the Life Tenant to divest any Remainderperson of their Remainder Interest." The Department's conclusion followed from that: because the life tenants "retain all rights to the subject properties," the remainderpersons' interests "if any, is contingent upon the death of the Life Tenants."
Being named on that kind of deed confers considerably less than being named on an ordinary one. It is closer to being a beneficiary than an owner, and the life tenant can revoke it.
Vested and contingent remainders behave differently on one question that matters enormously: what happens if the remainderman dies first. A remainder is vested where the person is identified and nothing has to happen except the ending of the life estate. It is contingent where it depends on a condition, most often on surviving the life tenant. California's general rule is that future interests "pass by succession, will, and transfer, in the same manner as present interests," so a vested remainder held by someone who dies before the life tenant does not disappear — it passes under their own will or by intestacy, and their heirs step into the position. A remainder expressly conditioned on surviving does the opposite and simply fails, which is why instruments so often name an alternative taker. California contemplates that too: "two or more future interests may be created to take effect in the alternative, so that if the first in order fails to vest, the next in succession shall be substituted for it."
The practical consequence is that "remainderman" describes a range of positions, from near-certain ownership to a revocable expectancy, and the document is the only way to tell which one a person has.
The one lever available during the life tenancy is a waste claim. A life tenant who lets the property deteriorate, allows taxes to go unpaid, or strips value out of it is damaging property that belongs to somebody else, and that is actionable. California's Code of Civil Procedure section 732 provides that where a "tenant for life or years" commits waste, "any person aggrieved by the waste may bring an action against him therefor, in which action there may be judgment for treble damages." The remedy is real and the practical difficulty is obvious: in the ordinary family case the defendant is a parent, and the choice is between litigation and nothing.
Basis is set at the life tenant's death, not at the date of the deed, in the ordinary retained-life-estate case. Where the person who created the arrangement kept possession or the right to income for life, Internal Revenue Code section 2036, headed "Transfers with retained life estate," includes the property in their gross estate, and section 1014(b)(9) treats property required to be included in the gross estate as acquired from the decedent. The result is that the remainderman takes the date-of-death value as their starting basis rather than inheriting the original owner's. That is the tax feature that usually justifies the arrangement, and the pages on the basis reset and on the ceiling that constrains it cover the mechanics.
A remainder is exposed to the remainderman's own life, which the person who created it rarely considers. Because it is transferable property, it can be reached by the remainderman's creditors, can be entangled in their divorce, and passes at their death if vested. A parent who names three children as remaindermen has, without meaning to, introduced three sets of creditors, spouses and eventual heirs into the future ownership of the house.
