Will & Trust
Without a Will, your assets could be more burdensome than beneficial to your family at a time when they are most vulnerable. The distribution involved can be a long legal process especially if there is a dispute.
You should never assume that your assets would automatically go to the person you want to benefit. Give them security by making a Will and the law will protect your wishes.
Many people have many different needs. These can be easily solved by setting up a special specific purpose Trust to protect their assets and loved ones. The beneficiaries are not limited to family members only.
