This lawsuit arises from a dispute on a contract for the sale of land. At closing on the land sale contract, Mr. McCrackin, seller of the land, showed concern that social security supplemental income checks to him and his wife would be terminated if the land sale was completed. The purchaser of the land and her attorney, Mr. Clay, thereupon signed an agreement to the effect that if the checks were cancelled as a direct result of the land sale that they would be responsible for making such payments
The court properly granted summary judgment. The additional agreement was without consideration. "An agreement on the part of one to do what he is already legally bound to do is not a sufficient consideration for the promise of another.” Johnson v. Hinson, 188 Ga. 639, 644 (4 SE2d 561) (1939); Holliday & Co. v. Poole, 77 Ga. 159 (1886). The only thing received by the purchaser as a result of the subsequent agreement was the seller’s signature on the deed at closing. As this was already required by the land sale contract, the subsequent agreement was "a nudum pactum and void as having no consideration to support the promise.” Davis & Co. v. Morgan, 117 Ga. 504, 505 (43 SE 732) (1903).
Judgment affirmed.
