Si accepto latum fuerit ei, qui non verbis, sed re obligatus est, non liberatur quidem, sed exceptione doli mali vel pacti conventi se tueri potest. 1Inter acceptilationem et apocham hoc interest, quod acceptilatione omni modo liberatio contingit, licet pecunia soluta non sit, apocha non alias, quam si pecunia soluta sit.
Ulpianus, Rules, Book II. If a release should be granted to someone who is not bound by words, but by the property, he will not, indeed, be freed from liability, but he can defend himself by an exception on the ground of bad faith, or on that of an informal agreement. 1The following difference exists between a release and a receipt: by a release, absolute discharge from liability takes place, even if the money has not been paid; but a receipt does not have this effect, unless the money has actually been paid.
