Are Some Things not Practical to be Put in a Will?
It is usually a substantial time following one’s demise until the will is read. The reading of the will is a formal matter, and may take some time to be arranged. That means that funeral instructions that some testators insist must be part of their will are often not followed, and usually not even discovered until it is too later. This probably results in some anguish for the already-distressed survivors who are tasked to handle funeral matters.
Pets cannot be included at beneficiaries of a will, and it is often difficult to setup support for them using the will. Some states have started allowing a trust to be setup for pets.
Personal Sentiments are usually better put in a separate document also. It is often best to simply leave your sentiments with a trusted person to bring forth, if that is the sort of thing you thing you think is important.
