UNDERLEASE, contracts. An alienation by a tenant of a part of his lease, reserving to himself a reversion; it differs from an assignment, which is a transfer of all the tenant's interest in the lease. 3 Wils. 234; S. C. Bl. Rep. 766. And even a conveyance of the whole estate by the lessee, reserving to himself the rent, with a power of re-entry for non-payment, was held to be, not an assignment, but an underlease. Str. 405. In Ohio it has been decided that the transfer of only a part of the lands, though for the whole term, is an underlease; 2 Ohio, R. 216; in Kentucky, such a transfer, on the contrary, is considered as an assignment. 4 Bibb. R. 538.

2. In leases there is frequently introduced a covenant on the part of the lessee, that he will not underlet the premises, nor assign the lease. This refers to the voluntary act of the tenant, and the covenant is not broken when the lease is transferred without any act on his part; as, if it be sold by the sheriff on execution, or by assignees in bankruptcy, or by an executor. 8 T. R. 57; 3 M. & S. 353; 1 Ves. 295.

3. The underlessor has a right to distrain for the rent due to him, which, the assignor of a lease has not. The under-lessee is not liable personally to the original lessor, nor is his property subject to his claim for rent longer than while it is on the leased premises, when it may be distrained upon. The assignee of the lessee stands in a different situation. He is liable to an action by the landlord or his assignee for the rent, upon the ground of privity of estate. 1 Hill. Ab. 125, 6; 4 Kent, Com. 95; 9 Pick. R. 52; 14 Mass. 487; 5 Watts, R. 134. Vide 2 Bl. R. 766; 3 Wils. 234; 4 Campb. 73; Bouv. Inst. Index, tit. Underletting.

UNDERTAKING, contracts. An engagement by one of the parties to a contract to the other, and not the mutual engagement of the parties to each other; a promise. 5 East, R. 17; 2 Leon. 224, 5; 4 B, & A. 595.

UNDERTOOK. Assumed; promised.

2. This is a technical word which ought to be inserted in every declaration of assumpsit, charging that the defendant undertook to perform the promise which is the foundation of the suit; and this though the promise be founded on a legal liability, or would be implied in evidence. Bac. Ab Assumpsit, F; 1 Chit. Pl. 88, note p.

UNDER-TUTOR, law of Louisiana. In every tutorship, there shall be an undertutor, whom it shall be the duty of the judge to appoint at the time letters of tutorship are certified for the tutor.

2. It is the duty of the under-tutor to act for the minor, whenever the interest of the minor is in opposition to the interest of the tutor. Civil Code, art. 300, 301; 1 N. S. 462; 9 M. R. 643; 11 L. R. 189; Poth. Des Personnes, partie prem. tit. 6, s. 5, art. 2. Vide Pro-curator; Protutor.

UNDERWRITER, insurances. One who signs a policy of insurance, by which he becomes an insurer.

2. By this act he places himself as to his responsibility, in the place of the insured. He may cause a re-insurance (q. v.) to be made for his benefit; and it is his duty to act with good faith, and, without quibbling, to pay all just demands against him for losses. Marsh. Ins. 45,

UNDIVIDED. That which is held by the same title by two or more persons, whether their rights are equal, as to value or quantity, or unequal.

UNICA TAXATIO, practice. The ancient language of a special award of venire, where of several defendants, one pleads, and one lets judgment go by default, whereby the jury, who are to try and assess damages on the issue, are also to assess damages against the defendant suffering judgment by default. Lee's Dict. h. t.

UNILATERAL CONTRACT, civil law. When the party to whom an engagement is made, makes no express agreement on his part, the contract is called uni-lateral, even in cases where the law attaches certain obligations to his acceptance. Civ. Code of Lo. art. 1758. Code Nap. 1103. A loan of money, and a loan for use, are of this kind. Poth. Obl. part 1, c. 1, s. 1, art. 2; Lee. Elemen. §781.
