Bouvier's Law Dictionary, Revised 6th Ed (1856):

SURRENDER, estates, conveyancing. A yielding up of an estate for life or
years to him who has an immediate estate in reversion or remainder, by which
the lesser estate is merged in the greater by mutual agreement, Co. Litt.
337, b.
     2. A surrender is of a nature directly opposite to a release; for, as
the latter operates by the greater estate descending upon the less, the
former is the falling of a less estate into a greater, by deed. A surrender
immediately divests the estate of the surrenderer, and vests it in the
surrenderee, even without the assent (q.v.) of the latter. Touchs. 300, 301.
     3. The technical and proper words of this conveyance are, surrender and
yield up; but any form of words; by which the intention. of the parties is
sufficiently manifested, will operate as a surrender, Perk. Sec. 607; 1 Term
Rep. 441; Com. Dig. Surrender, A.
     4. The surrender may be express or implied. The latter is when an
estate, incompatible with the existing estate, is accepted or the lessee
takes a new lease of the same lands. 16 Johns. Rep. 28; 2 Wils. 26; 1 Barn.
& A. 50; 2 Barn. & A. 119; 5 Taunt. 518, and see 6 East, R. 86; 9 Barn. &
Cr. 288 7 Watts, R. 128. Vide, generally, Cruise, Dig. tit. 32, c. 7; Com.
Dig. h.t.; Vin. Ab. h.t.; 4 Kent, Com. 102; Nels. Ab. h.t.; Rolle's Ab. h.t.
11 East, R. 317, n.
     5. The deed or instrument by which a surrender is made, is also called
a surrender. For the law of presumption of surrenders, see Math. on Pres.
ch. 13, p. 236; Addis. on Contr. 658-661.
