Wills are the traditional, and still most popular, method of transferring assets upon death. The Will also appoints someone, often a relative, to serve as personal representative to handle your affairs upon death.
Wills can include trusts to manage and distribute assets through a trustee after your death. Your estate planning documents will include the appointment of someone you trust to manage your affairs should you become disabled, a directive to express your desires regarding end of life decisions, and even a directive to deal with your remains. Estate plans with Wills generally remain more affordable than drafting, and funding, a trust.
