This is the most basic testamentary instrument, and is likely the most used and, 95% of the time, the most effective and efficient way to distribute your assets upon your demise.

Massachusetts has some fairly formal requirements that must be met in order for a Will to be allowed by the probate court.

This state does not recognize "holographic" Wills, which are handwritten and signed by the testator (the person whom the Will is written for). This alone will not suffice.

All Wills must be witnessed by at least two disinterested (read: not gettting any money) adults who are in the line of site of the testator.

Usually the Will names an executor (male) or executrix (female) or multiples of either to be in charge of making sure the instructions contained in the Will are carried out dutifully.

There are any number of legal considerations to any disposition of property, and tax consequences, which is why anybody attempting to draft a Will should consult an experienced attorney.
