(In Arabic: تصرف) The tendency of the will to have a specific legal effect, and this effect is represented by the creation of a right that results from it. For example, the contracts concluded with the transfer of ownership of real estate between two parties, as it is a legal act based on the convergence of two wills, and a system that acquires real rights. The same applies to the will, as it is a legal act based on a unilateral will, and it also acquires specific rights.
