True test of presence in signing of wills
The true test of presence of the testator and the witnesses in the execution of a will is not whether they actually saw each other sign, but whether they might have been seen each other sign, had they chosen to do so, considering their mental and physical condition and position with relation to each other at the moment of inscription of each signature.
But, it is especially to be noted that the position of the parties with relation to each other at the moment of the subscription of each signature, must be such that they may see each other sign if they choose to do so. This, of course, does not mean that the testator and the subscribing witnesses may be held to have executed the instrument in the presence of each other if it appears that they would not have been able to see each other sign at that moment, without changing their relative positions or existing conditions.
