Legal Question in Wills and Trusts in Massachusetts

A deed is valid as long as the signatory was competent to sign it and understood what they were signing.

However, if the deed is made to the detriment of other beneficiaries or the creditors of the estate of the person in end of life care, it can and probably will be challenged.

I agree with attorney Roth that a deed will be valid so long as the person was competent. The facts you present may lead to a finding of incompetence, but it is impossible to say without knowing all of the relevant facts.
