Wills and trusts are documents that preserve your wishes after you pass away, preventing family members and other heirs from fighting over your assets upon your death. These are flexible documents that give you leeway as to where you'd like your assets to go, and allow you to provide specific directions for the distribution of your Estate. Trusts, powers of attorney, healthcare directives and living wills govern your financial and medical affairs when you become incapacitated. Estate planning documents are the foundation of the long-term goals of the estate planning process.
